Numerous surgical techniques have been developed as effective means to facilitate orthodontic treatment, but they may cause significant postoperative discomfort. Piezocision was established as a flapless and minimally invasive technique to accelerate orthodontic tooth movement by combining small vertical incisions and piezoelectric corticotomies. Computed tomography is combined with the Piezocision technique to fabricate CAD/CAM surgical guides to prevent iatrogenic damage. A method to combine computer-assisted dynamic navigation with Piezocision is introduced here. CBCT was combined with motion-tracking technology to allow real-time tracing of the piezoelectric instruments during the surgical procedure. This technique delivers the location of the piezoelectric knife in regard to roots and important anatomical structures to increase the safety and accuracy during corticotimies.

Objective: This study aimed to evaluate the degrees of dependence and presence of bacterial plaque in children with autism spectrum disorder (ASD) and the quality of life of children and their caregivers. Method and materials: This was a cross-sectional observational study. This study included 119 individuals with ASD and their caregivers. Data were collected through a sociodemographic questionnaire, WHOQOL-Bref, and Burden interview to measure quality of life and caregiver burden, respectively. The Autoquestionnaire Qualité de Vie Enfant Imagé questionnaire, adapted in game format, was applied to verify quality of life in children with ASD. An oral clinical examination evaluated the visible plaque index. The collected data were tabulated and organized for statistical analysis with a significance level of 5%. Results: It was observed that 52% of the children had a severity of ASD level 1; 70% were dependent for general activities, and 65% were dependent for oral hygiene. Of the 77 children who thoroughly answered the questionnaire about their quality of life, 64.9% had good quality of life, and 35.1% had scores below 48, that is, low quality of life. In general, the caregivers generally presented quality of life with a rate of 60.95 (good) points on the scale. It was observed that gingival bleeding greater than 30% is two (ASD 2 + ASD 3) to three (ASD 3) times more likely to occur in patients who have higher levels of ASD (P < .004). Conclusion: It was concluded that the quality of life of individuals with ASD was good, that most children are dependent for their daily activities and oral hygiene, and that they showed reasonable plaque control. On the other hand, the caregivers presented low quality of life and moderate burden. [ABSTRACT FROM AUTHOR]

Peri-implant diseases are defined as bacterial plaque-induced inflammatory conditions affecting implant-surrounding tissues and are classified as peri-implant mucositis and peri-implantitis. Peri-implant mucositis is characterized by an inflammatory lesion that resides in the soft tissue compartment, whereas at peri-implantitis sites the lesions also feature progressive loss of implant-supporting bone. Inflammation resolution and disease progression arrestment are the main therapeutic endpoints of the treatment of peri-implant diseases. The present position paper displays the current evidence and clinical recommendations of the European Association for Osseointegration for the treatment of peri-implant diseases. Mechanical biofilm removal along with the reinforcement of patient-administered oral hygiene is considered the standard treatment for managing peri-implant mucositis. It is recommended to assess the outcomes of peri-implant mucositis treatment 2 to 3 months after therapy, and repeated intervention should be considered in the absence of treatment success. Peri-implantitis treatment should follow a stepwise treatment approach, starting with nonsurgical treatment followed by surgical intervention, if that is not sufficient. Surgical peri-implantitis therapies include nonreconstructive, reconstructive, and combined treatment modalities. Implantoplasty may be advocated for the treatment of supracrestal peri-implant defects, whereas reconstructive therapy is indicated at peri-implantitis sites featuring intraosseous defects with a depth ≥ 3 mm. Adjunctive reconstructive measures may be beneficial in enhancing radiographic defect fill and maintaining postoperative soft tissue levels, which may have a great impact in esthetic cases. The adjunctive use of systemic antibiotics during surgical therapy does not seem to improve the clinical outcomes. Regular supportive peri-implant therapy with biofilm removal should be an integral part of the treatment protocol for peri-implant diseases. In the presence of advanced bone loss around implants that do not play a strategic role in masticatory function, implant removal may be considered immediately. [ABSTRACT FROM AUTHOR]

Purpose: To describe the use of digital technology to surgically guide the shell technique using allogenic cortical plates for a fully guided bone augmentation procedure. Materials and Methods: A total of 10 patients who required bone augmentation for implant placement were included in this study. Allogenic cortical plates were planned using CAD/CAM to have identical thickness to the original cortical plates, then were digitally positioned and shaped to outline the bone defect according to the existing anatomical details. A cutting pattern and a surgical template were manufactured according to the digitally preplanned bone graft and the intraoral setting. Results: A total of 12 horizontal bone grafting procedures were performed using the shell technique with allogenic cortical plates. All grafting procedures were deemed successful and allowed for ideal 3D implant positioning. Of the 12 bone grafting procedures, which used a surgical template to position the cortical plate, 3 required an adjustment to reposition the plate to a more ideal position. Conclusions: Digital technology was used to create a surgical template to guide the shell bone grafting technique with allogenic cortical plates. All surgical templates offered a fixed support to hold the cortical allogenic plate in the preplanned position, offering a predictable, simplified, and accurate guided bone grafting procedure. Further studies on a larger population of patients are necessary to assess those results and to verify the treatment approach described in this study. [ABSTRACT FROM AUTHOR]

Objectives: Inflammatory disorders including periodontitis have been investigated for their impact on systemic inflammation and bone health. The present study was conducted with an aim to evaluate impact of control of periodontal inflammation through subgingival instrumentation on serum interleukin 6 and serum C-terminal telopeptide of type I collagen (CTX) in premenopausal females with stage II and III periodontitis. Method and materials: In this single-arm prospective study, periodontal parameters, serum interleukin 6, serum CTX, and hematologic parameters (total leukocyte count, differential leukocyte count, platelet count, mean platelet volume, and platelet distribution width) were assessed at baseline. Subgingival instrumentation was done, and oral hygiene instructions were given. At week 4, professional plaque control was performed, and oral hygiene instructions were reinforced. Serum and hematologic parameters were reassessed at 8 weeks after subgingival instrumentation, in individuals meeting the clinical endpoints (ie, bleeding on probing < 10%). Results: There was significant reduction in serum interleukin 6 of 0.168 ± 0.164 pg/mL (P = .000), and serum CTX of 17.459 ± 4.363 pg/mL (P = .000) at 8 weeks after subgingival instrumentation. There was significant decrease in eosinophil count (P = .018) and mean platelet volume (P = .016) at 8 weeks after subgingival instrumentation; however, no significant change was found in other hematologic parameters. Conclusion: Following subgingival instrumentation, biomarkers of both systemic inflammation (interleukin 6) and bone turnover (CTX) were observed to reduce significantly. This finding hints towards a positive impact of periodontal intervention on bone health. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the efficacy of the adjunctive use of tea tree oil (TTO) for dental plaque control and nonsurgical periodontal treatment (NSPT). Materials and Methods: Three electronic databases were searched from 2003. The reference lists of the included articles and relevant reviews were also manually searched. Randomised controlled trials reporting the clinical outcomes of the topical use of TTO as an adjunct to daily oral hygiene or scaling and root planing (SRP) were included. Regarding the use of TTO as an adjunctive to daily oral hygiene, the primary outcome was plaque index (PI) reduction. Regarding the use of TTO as an adjunctive to SRP, probing pocket depth (PPD) reduction and clinical attachment level (CAL) gain were the primary outcomes. The secondary outcomes were adverse events. Results: Eleven studies were included for qualitative analysis, 9 studies were included for quantitative analysis, and 6 studies were included to examine the application of TTO mouthwash as an adjunctive to daily oral hygiene. In addition, three studies were included to analyse the subgingival use of TTO adjunctive to SRP at selected sites. The results indicated a nonsignificant improvement in PI reduction in the TTO mouthwash group compared with placebo. The incidence of adverse events was statistically significantly greater in the CHX group than in the TTO group. For subgingival use of TTO adjunctive to SRP, beneficial effects were observed in the TTO group compared with SRP alone in terms of PPD and CAL at both three and six months post-treatment. However, an unpleasant taste was reported in three out of four studies. Conclusion: There is a lack of strong evidence to support the beneficial effects of TTO. Studies with larger sample sizes and standardised evaluation criteria are needed to further demonstrate the clinical relevance of TTO. [ABSTRACT FROM AUTHOR]

Purpose: To compare the effectiveness of an interproximal brush, a water flosser, and dental floss in removing plaque and reducing inflammation around implant-supported crowns. Materials and Methods: A randomised controlled trial was conducted involving 45 participants with implant-supported single crowns. The participants were randomly assigned to three groups: interproximal brush, water flosser, and dental floss. Plaque index scores, gingival index scores, and interleukin-6 (IL-6) levels were assessed at baseline and after a two-week period. Statistical analysis was performed to compare the outcomes among the groups. Results: Following the second visit, improvements in plaque control were observed across all three interdental cleaning methods. The water flosser demonstrated a slight reduction in IL-6 levels (60.17 ± 3.07 vs 58.79 ± 4.04) compared to the initial visit, although this decrease was not statistically significant. Conversely, both the interdental brush and dental floss exhibited a slight increase in IL-6 levels at the second visit (60.73 ± 2.93 and 55.7 ± 10.64, respectively) compared to the mean at the first visit (58.38 ± 3.24 and 54.6 ± 2.22, respectively). Among the groups, only the interproximal brush demonstrated a statistically significant difference in IL-6 levels (p=0.008), while no statistically significant differences were observed in the dental floss and water flosser groups. Conclusion: Within the study’s limitations, our findings suggest that all three methods of interdental cleaning effectively improve plaque control and reduce gingival inflammation. However, using a water flosser appears to reduce inflammation more effectively, highlighting its potential advantage over the other two methods. Further research is needed to evaluate the long-term efficacy and impact of these methods on implant survival. [ABSTRACT FROM AUTHOR]

Objective: The predictability and long-term success of periodontal regeneration begins with oral hygiene education, disease management, and an individually tailored periodontal maintenance protocol. The treatment outcomes could be enhanced when biologics and bone grafts are combined. The aim of this report was to describe the outcome of two complex infrabony defects in the same patient treated with recombinant human platelet-derived growth factor-BB (rhPDGF-BB) and freeze-dried bone allograft (FDBA) over 10 years. Case presentation: Two complex infrabony defects were treated following guided tissue regeneration principles and procedures. Fullthickness flaps were raised to allow visualization of the defects. The areas were debrided, and exposed root surfaces were planed. FDBA and rhPDGF-BB were combined to fill both defects. A collagen membrane was used over the bone graft in one case. The flaps were reapproximated to achieve primary closure. The patient was seen for regular periodontal maintenance visits and clinical and radiographic follow-ups over 10 years. Throughout the examination periods, the probing depths improved without bleeding on probing, and there was radiographic evidence of bone regeneration. Conclusion: The growth factorinfused bone graft was successfully utilized for periodontal regeneration in complex bony defects. [ABSTRACT FROM AUTHOR]

The purpose of this clinical study was to assess the feasibility of forced orthodontic extrusion with the Tissue Master Concept to retain subgingivally fractured teeth as abutments for which extraction and replacement would be equal treatment opportunities. Participants were recruited from a group of consecutive patients in need of prosthodontic rehabilitation. In total, 36 deeply destroyed teeth in 31 patients underwent forced orthodontic extrusion with forces exceeding 50 g to reestablish biologic width and ensure a 2-mm dentin-ferrule design prior to single-crown restoration. The primary endpoint was the success of the extrusion in terms of the ability to restore the respective abutment tooth. Information about overall treatment time, frequency, and reasons for failure were collected. Four patients dropped out of the treatment. For the remaining 27 participants, data were fully collected. The amount of extrusion ranged between 2 and 6 mm (3.5 ± 0.9 mm), and the mean duration until retention was 20 ± 12 days. On average, patients returned three (± 3) times for control visits after extrusion. Adhesive failure (n = 6) and orthodontic relapse (n = 2) were the most frequent complication types. Forced orthodontic extrusion may be a useful tool to restore teeth evaluated as nonrestorable. [ABSTRACT FROM AUTHOR]

Background: A comprehensive summary of evidence about oral health in slum settings that could inform policy directions is lacking. Objective: To summarise the latest evidence regarding oral disease burden and their determinants, perceptions, practices, and service utilization in the slums and non-slum urban settings of LMICs. Design: Systematic review Data sources: Embase and MEDLINE (Ovid); PubMed; Scopus, Web of Science, CRD DARE Database; ELDIS; Essential Health Links; HINARI; African Index Medicus (AIM); and Bioline International, all searched from January 2000 to June 2023 using slum-related terms. Eligibility criteria: Empirical studies of all designs were eligible. Studies published in English with full-text available and reporting disease burden, perceptions, behaviours and service utilisation related to oral health of residents of slums or broader settings including slums in low and middle-income countries were included. Data extraction, quality assessment, synthesis and reporting: Studies were categorised and data were extracted and charted according to a preliminary conceptual framework refined by emerging findings. The Mixed Methods Assessment Tool (MMAT) was used to appraise the quality of empirical studies. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and (where applicable) the Synthesis Without Meta-analysis (SWiM) guideline were adopted for guiding synthesis and reporting. Results were tabulated and narratively summarised. Results: Full-text articles for 56 records were assessed for eligibility and 23 of the articles were included in this review. The majority (13 studies, 57%) were conducted in Asia, and nine studies (39%) in Africa. Six focused on slums (two examined slum and urban non-slum and four examined purely slum settings), two examined general urban settings, eight included both rural and urban areas in their settings, two examined disadvantaged/low socioeconomic, one assessed rural/urban/metropolis/municipal/district, three covered the national population or whole country, and one looked at high versus low socioeconomic regions. The commonest oral diseases reported were dental caries (prevalence: 13% - 76%), and periodontal diseases (prevalence: 23% - 99%). These were higher in slum settings and showed differences across age groups, gender, and socioeconomic classes. Most participants in the studies perceived their oral health status as satisfactory, a belief commoner among younger people, males, those in higher socio-economic classes, and employed. Mouth cleaning was mostly once daily, usually in the mornings. The use of toothpaste and brush was commonest. Other oral hygiene implements included toothpowder, chewing-stick, neem, charcoal, sand, snuff, salt, and the fingers. There was widespread engagement in home remedies for oral disease cure or prevention, while the use of professional dental care facilities was generally low and problem-driven. Conclusion: The systematic review identified a sparse body of literature on oral health surveys in slums and other urban settings in LMICs. Available data suggest a high oral disease burden, worse in slums, use of inappropriate mouth cleaning tools, self-care practices for pain relief, and few visits to care facilities. Systematic review registration: Systematic review registration with PROSPERO in February 2020, number CRD42020123613. [ABSTRACT FROM AUTHOR]

This study evaluated correlations between poor dental health and craniomandibular morphology for the Radcliffe Infirmary population buried between 1770 and 1855. The Radcliffe Infirmary is situated in Oxford, 90 km northwest of London, in what used to be a rural area. The original report for this population observed high prevalence rates of dental caries, antemortem tooth loss (AMTL), and periodontal disease. Industrial societies are acknowledged to have highly processed foods that not only are detrimental to dental health but also require less mastication. This softening of diet is suggested to be the leading influence on the modern morphology of the skull. By using two‐dimensional geometric morphometrics (GM) and linear measurements of the skull, the Radcliffe population was evaluated for the effects of poor dental health and decreased wear on the masticatory structures. High frequencies of AMTL, periodontal disease, and caries and low amounts of dental wear were observed in this sample population. Caries and AMTL showed weak correlations with skull shape and craniomandibular dimensions according to the results of the morphometric analysis and Kendall's tau. Dental wear correlated with a wide bizygomatic breadth and a long narrow skull shape for the males only. Periodontal disease was the only dental health variable not correlated with shape or size. This study confirmed that the Radcliffe population ate a cariogenic diet and suggests that dental wear and pathology weakly correlates with craniomandibular shape and size. This unpredicted finding may be due to the limitations of two‐dimensional shape analysis, a small sample size, and the sampling strategy. Future research is highly encouraged to better understand the consequences of poor dental health for skull morphology. [ABSTRACT FROM AUTHOR]

ABSTRACT Objectives Design Sample Methods Results Conclusion Good oral hygiene is essential for schoolchildren's well‐being. However, lack of knowledge, negative attitudes, and poor oral hygiene practices may predispose to oral‐related diseases. This study aimed to examine the effectiveness of a nurse‐led oral hygiene program on schoolchildren's knowledge, attitudes, and practices.A quasi‐experimental design with pre‐and‐post‐test was used.Using the convenience sampling technique, we recruited 400 schoolchildren, aged 11–12 and in grades 5–6, from two primary schools in Egypt.The study was conducted from September 2022 to May 2023. The Oral Hygiene Program served as the primary intervention. This program contains health education topics (e.g., the importance of oral hygiene, techniques for effective tooth brushing, and dietary choices that promote dental health). Three visits were conducted (Visit 1: introduction of the program purpose and objectives and pre‐test scores collection, Visit 2: implementation of oral hygiene topics, and Visit 3: post‐test scores collection). We used three self‐report instruments (Oral Health Knowledge Questionnaire, Hiroshima University's Dental Behavioral Inventory, and Oral Health Practice Questionnaire) for pre‐ and post‐test. Paired T test and Pearson correlation analysis were used for data analysis.After the intervention program, the oral hygiene program effectively enhanced schoolchildren's knowledge, attitudes, and practices. The post‐intervention mean scores were 7.83 ± 0.488 (knowledge), 6.63 ± 1.7 (practices), and 9.33 ± 1.1 (attitudes). High statistically significant differences were noted between schoolchildren's oral health knowledge, attitudes, and practices before and after implementing the program (p = 0.000).There were enhancements in the level of knowledge, with improved positive attitudes and satisfactory practices among schoolchildren after the implementation of the oral hygiene program. Integrating oral hygiene programs into the general curriculum in primary schools and training school nurses, caregivers, and teachers in implementing oral hygiene programs could improve oral health knowledge, attitudes, and practices for preventing oral problems.

Background: One of the most prevalent oral health issues affecting mankind is tooth loss. Besides extractions due to periodontal disease and caries, accidents and lack of dental knowledge can also result in tooth loss. Nevertheless, no known published studies have examined how edentulous patients in Uganda have lived with tooth loss. The objective of the present study was to investigate experiences of tooth loss among Ugandan edentulous patients attending Makerere University Dental Hospital. Methods: This was a cross-sectional qualitative study using purposive recruitment of respondents. A total of 15 respondents were chosen from a variety of socio-economic groups. Qualitative data were collected using oral interviews in form of note taking and an audio-recorder. The data collected comprised the causes of tooth loss, the physical and psychological effects of losing teeth, the difficulties in managing oral hygiene when one is toothless, coping mechanisms, and supportive interventions after losing natural teeth. The collected data were transcribed and analyzed thematically using a software, Atlas Ti. The generated qualitative data were summarized as text, while demographic characteristics were presented in a table. Results: Oral infections such as periodontal disease (which destroy tooth supporting tissues), tooth decay and trauma from accidents were reportedly the main causes of tooth loss. In case of tooth pain as a first symptom, most patients choose self-medication with over-the-counter drugs and home remedies. They only consult dental professionals when the condition deteriorates. Tooth loss was associated with problems of eating, facial aesthetics and low self-esteem. Conclusion: The present study found that tooth loss was caused by periodontal disease, tooth decay and trauma from accidents. Loss of teeth was escalated by poor health seeking behavior. Tooth loss resulted in pain, eating difficulties, speech difficulties, poor facial appearance and consequently low self-esteem. [ABSTRACT FROM AUTHOR]

Background: The importance of oral hygiene maintenance is of prime importance in dentulous and edentulous individuals. There are numerous types of bacteria which colonise in the oral cavity. Completely edentulous individuals have to follow proper hygiene procedures to keep their dentures germ free which can prevent numerous oral conditions. The main aim of this text was to briefly understand the interaction between microorganisms and denture, discuss the various methods of preventing plaque formation on dentures and highlight the natural antimicrobial agents in detail. Main body: There are numerous factors which play a role in biofilm formation. Methods such as patient education, maintenance of denture hygiene and use of pharmacological methods have proven to effectively reduce or prevent the growth of microorganisms. Pharmacological agents can broadly be classified into natural and synthetic based on their source of origin. Based on their mechanism of action, they are classified as biocides, biocide releasing polymers and surface acting agents. The use of natural v/s synthetic products has always seen positives and negatives. Apart from the antimicrobial activity, the influence of these agents on the mechanical properties also remains an important aspect. This text highlights the various natural antimicrobial agents that can be incorporated in the dentures and the effect they have on the mechanical properties of the dentures. Conclusion: The interaction between microorganisms and denture has been explored in detail. The various natural and synthetic antimicrobial agents have been enlisted following which the natural antimicrobials have been discussed in detail. The various natural products have shown marked antimicrobial nature however, their influence on the mechanical properties is lacking. [ABSTRACT FROM AUTHOR]

Introduction: Nurses are the primary contact for caregivers of Children with Special Healthcare Needs (CSHCN). Parent counselling and health screening programs are undertaken in which nurses play an important role. Along with this, it is also essential to have knowledge of oral health and the importance of maintaining oral hygiene, especially for CSHCN. Aim: To evaluate the knowledge of nursing graduates regarding oral healthcare for CSHCN at baseline, one week and one month after a Structured Visual Pedagogy (SVP) intervention, and to compare their knowledge scores before and after the intervention. Materials and Methods: This pretest-posttest quasiexperimental study was conducted at Dr. D.Y. Patil College of Nursing, Pune, Maharashtra, India, between February 2023 and June 2023, among 60 nursing graduates. An SVP was curated and delivered to the study population. It was an audio-video discussion-based intervention covering the various domains of oral healthcare for CSHCN, including their oral manifestations, barriers to oral hygiene maintenance, and their management through counselling and timely referrals. Participants completed a pre-validated questionnaire at three intervals: before the intervention, one week after and one month after the intervention, and their knowledge was analysed. The data were analysed using International Business Machines (IBM) Statistical Package for Social Science (SPSS) software version 21.0, USA. Results: The mean age of study group was 21±0.85 years. Among the participants, 52 (86.6%) were females and 8 (13.4%) were males. Between the baseline and the first week of the SVP, as well as, between the baseline and the first month, nursing graduates' understanding of the oral health requirements of CSHCN increased. The mean knowledge score at the preintervention stage was 6.83±2.35; at one week post-intervention, the mean knowledge score was 14.40±1.50; and one month post-intervention, the mean knowledge score was 13.65±1.40. It was observed that there was a statistically significant increase in the mean knowledge score one week, as well as, one month post-intervention compared to the baseline (p-value<0.05). Conclusion: The SVP was highly effective among the nursing graduates, clearly highlighted its use as a training tool for nurses. [ABSTRACT FROM AUTHOR]

Background: Dental anxiety and odontophobia are common issues, leading to challenges with oral hygiene and dental health. Music distraction offers an effective and side effect-free solution to alleviate pain and increase the acceptability of dental treatments. Our meta-analysis aimed to assess the efficacy of music distraction in reducing patient anxiety during invasive dental procedures in children and adults. Methods: The PubMed, Web of Science, and Embase databases were searched for clinically controlled trials, using the keywords "music" and "dental anxiety". The main outcome measured was the anxiety score. A meta-analysis was conducted using a random-effects model to estimate the standardized mean differences (SMDs). The subgroup analyses were conducted based on age groups, music preferences, and music styles. The research protocol has been registered with PROSPERO (Registration ID: CRD42022357961). Results: A total of 24 controlled clinical trials involving 1830 participants met the inclusion criteria for the meta-analysis. Music distraction significantly reduced dental anxiety during invasive procedures under local anesthesia (SMD, −0.50; 95% CI, −0.80 to −0.21; p = 0.0009; I2 = 83%). Our subgroup analysis revealed that music distraction was more effective in adults (SMD, −0.51; p = 0.0007) than in children (SMD, −0.47; p = 0.13) in reducing dental anxiety. Regarding music selection, music chosen by the participant (SMD, −1.01; p = 0.008) demonstrated more anxiolytic effects than by the author (SMD, −0.24; p = 0.02). Regarding music styles, classical music (SMD, −0.69; p = 0.009) was associated with better anxiolytic effects in adults. Conclusions: Our meta-analysis supports the use of music to alleviate dental anxiety during invasive procedures. Listening to classical or customized music can serve as an effective adjunct to outpatient surgical care in dental clinics. [ABSTRACT FROM AUTHOR]

The concept of oral frailty was first proposed in Japan in 2014 by the "Joint Working Committee on Oral Frailty," consisting of three academic societies—the Japan Geriatrics Society, the Japanese Society of Gerodontology, and the Japanese Association on Sarcopenia and Frailty—to enhance public understanding of oral frailty. Oral frailty is a state between robust oral function (a "healthy mouth") and its decline, characterized by slight declines in oral function, including tooth loss and difficulties in eating and communicating, which increase the risk of impaired oral functional capacity but can be reversed with proper intervention and treatment. Oral frailty can be assessed using the Oral Frailty 5‐item Checklist (OF‐5) without the need for a dental health professional. Oral frailty is defined as having at least two of the following components: (i) fewer teeth, (ii) difficulty chewing, (iii) difficulty swallowing, (iv) dry mouth, and (v) low articulatory oral motor skills. Approximately 40% of community‐dwelling older adults have oral frailty. Oral frailty is associated with poor dietary variety, social isolation, physical frailty, disability, and mortality. This statement introduces the concept and definition of oral frailty, a new assessment tool (OF‐5), and concept diagrams for healthcare professionals and the general public. These tools aim to promote public awareness and facilitate collaboration between medical and dental healthcare providers. Geriatr Gerontol Int 2024; 24: 1111–1119. [ABSTRACT FROM AUTHOR]

ABSTRACT Objectives Methods Results Conclusion Clinical Significance This web‐based survey, conducted across multiple countries, sought to explore the factors that impact the decision‐making of clinicians when it comes to managing defective direct restorations.A survey consisting of 14 questions was sent out to dentists in 21 countries through various online platforms. The survey consisted of two sections. The first contained five questions about demographic information, while the second involved eight clinical scenarios. In the second part, participants were tasked with deciding whether to repair or replace defective composite and amalgam restorations.Three thousand six hundred eighty dental practitioners completed the survey. For composite restorations, repair was preferred in scenarios like partial loss or fracture (RR:0.72; 95% CI: 0.58, 0.89; p = 0.002), whereas replacement was favored for secondary caries (RR:2.43; 95% CI: 1.87, 3.16; p < 0.001) and open/defective margins (RR:3.93; 95% CI: 2.68, 5.76;p < 0.001). Amalgam restorations were mostly replaced across all scenarios. The main factors influencing decision‐making were caries risk, restoration size, and patient oral hygiene. Substantial heterogeneity was observed across countries.This study underscores the complexity of the decision‐making process and the need for evidence‐based guidelines to inform clinicians' decisions regarding restoration management. Patient‐level factors predominantly influence decision‐making, emphasizing the need for individualized approaches.The study reveals that the material type in the original restoration is a critical determinant, with composite restorations being repaired in specific scenarios, while amalgam restorations are consistently replaced across different countries. Key patient and tooth‐level factors, such as high caries risk, poor oral hygiene, and restoration size, significantly impact clinicians' decisions, often favoring replacement over repair. These findings underscore the necessity for evidence‐based guidelines to assist clinicians in making informed choices, ultimately enhancing the quality of patient care. [ABSTRACT FROM AUTHOR]

Objective: This case report presents a female adult patient who exhibits poor oral hygiene, a mutilated dentition with multiple missing teeth, and skeletal asymmetry. Clinical Considerations: Interdisciplinary treatment was necessary to maintain oral hygiene, treat caries, extract residual roots, and upright a horizontally impacted third molar using a miniplate. Additionally, orthodontic mini‐implants were utilized as anchorage to improve sagittal relationship and space closing. Space management was completed with orthodontic treatment, followed by restoration of the multiple missing teeth with dental implants. Conclusion: Consequently, an esthetic smile and functional occlusion were achieved by interdisciplinary treatment using orthodontic skeletal anchorage devices and dental implants. Clinical Significance: Missing mandibular first molar spaces were closed with retraction of the anterior teeth and protraction of the mandibular second molars using orthodontic mini‐implants. The mandibular right third molar, which should have erupted, was protracted with the second molar, while the horizontally impacted mandibular left third molar was uprighted using a miniplate and was protracted with an orthodontic mini‐implant. The missing maxillary lateral incisors were replaced with the maxillary canines, and the maxillary canines were replaced with the maxillary first premolars. The missing maxillary right second premolar and first molar and left first and second molars were successfully restored with dental implants. [ABSTRACT FROM AUTHOR]

Background: Differences in the effects of cream‐type denture adhesives and home liners remain unclear. Objective: This cross‐sectional study aimed to clarify the differences in the oral‐hygiene status and masticatory performance between participants using cream‐type denture adhesives and those using home liners. Methods: Masticatory performance with and without cream‐type denture adhesives and home liners was evaluated using colour‐changeable chewing gum. Oral hygiene was assessed using the tongue coating index (TCI). Propensity‐score matching was performed using oral moisture, presence of palatal or mandibular protuberances, type of residual ridge, denture type (complete or partial denture), and denture retention as background factors. Wilcoxon signed‐rank test was used to examine the differences in masticatory performance with and without cream‐type denture adhesives and home liners and differences in masticatory performance and TCI between the cream‐type denture adhesive and home‐liner groups. Results: This study included 38 and 40 cream‐type adhesive and home‐liner users, respectively, and 17 pairs were obtained after propensity‐score matching. The Wilcoxon signed‐rank tests showed that masticatory performance was significantly different with and without the use of home liners, and higher values were obtained with the use of home‐liners. However, the cream‐type denture adhesive and home‐liner groups showed no significant differences in terms of the change in masticatory performance with the use of them. Furthermore, Wilcoxon signed‐rank tests showed that TCI values were significantly high in the cream‐type adhesive group. Conclusion: The findings in this study suggest that home liners improve masticatory performance and that participants regularly using cream‐type denture adhesives have poorer oral hygiene.

Background: Inadequate daily oral hygiene care of dental prostheses could worsen general health of frail older people. The index of Augsburger and Elahi is often recommended to assess maxillary dental prosthesis plaque (DPP). Objective: To assess the reliability of an expanded and standardised DPP index of Augsburger and Elahi in trained and untrained examiners, and to determine the applicability of the index in community‐dwelling frail older people. Methods: Ten community‐dwelling frail older persons with complete and partial removable dental prostheses (RDPs) (mean ± SD age = 87.9 ± 8.4 years) participated. Seven persons were revisited after 3 months. The index was expanded with mandibular RDPs. Standardisation was achieved with a specially designed reference sheet. The RDPs were photographed after plaque colouring. Two trained examiners scored the photographs; thereafter, two untrained examiners. One trained examiner scored the photographs again after 3 weeks. Changes in DPP over the 3‐month period were assessed with Wilcoxon signed‐rank test. Inter‐ and intra‐examiner reliability was assessed with intraclass correlation coefficients (ICCs). Results: The DPP scores did not change significantly over time (Z = −0.594, p = 0.553). Inter‐examiner reliability was excellent in the trained examiners (ICC = 0.859–0.947), and fair‐to‐good in the untrained examiners (ICC = 0.671–0.703). Intra‐examiner reliability was excellent (ICC = 0.941–0.962). Conclusion: The proposed expansion and standardisation of the DPP index has an excellent inter‐ and intra‐examiner reliability when performed by trained examiners, and a fair‐to‐good inter‐examiner reliability by untrained examiners. Therefore, the index could be recommended for application in dental prostheses‐wearing older persons and could be useful for awareness and education of professional and informal caregivers and the older persons themselves.

Objectives: The objectives of this study were to determine the prevalence of root caries (RC) in South Coastal population of India, to identify the risk indicators associated with it and to describe some clinical characteristics of RC lesions. Materials and Methods: A cross-sectional study was conducted with a sample size of 1062 subjects to assess the prevalence of RC. Each subject underwent an oral examination, performed by a single-calibrated examiner. Questionnaires were used to collect the data on oral hygiene habits, diet, smoking, alcohol habits, systemic conditions, and education level. Univariate and multivariable regression analyses were performed to identify the risk indicators associated with RC. Results: The prevalence of RC was found to be 7.5%, with a mean RC Index of 17.66%. The results of multiple logistic regression showed that age (≥40 years), systemic conditions, and exposed root surfaces were statistically significantly associated with RC (P < 0.05). Conclusion: RC is prevalent not only in the older age group but also the younger adults in this cohort. This study suggests an association between RC and the variables age (≥40 years), exposed root surfaces and systemic conditions. [ABSTRACT FROM AUTHOR]

Background/Objectives: The miswak, crafted from the Salvadora persica tree, is a traditional teeth-cleaning twig that has served as a natural substitute for toothbrushes and toothpaste across diverse regions for centuries. This study aimed to evaluate and compare the effectiveness of miswak and a conventional toothbrush in reducing dental plaque and gingivitis over a two-week period. Methods: This two-week randomized, single-blind (clinical investigator), two-parallel-arm clinical trial was conducted at Princess Nourah University College of Dentistry (PNUCD). Stratified random sampling identified sixty participants who were then randomly assigned to two study groups: the miswak group and the toothbrushing group. To facilitate data collection, a self-designed form was employed to document participants' initials, assigned group, the Silness and Loe plaque index, and the Loe and Silness gingival index. The clinical examination, conducted by two blinded and trained examiners using a mouth mirror and explorer under natural light, aimed to assess the specified indices. The collected data were analyzed using IBM SPSS Statistics, Version 22. Results: Following the intervention, the miswak group exhibited no significant change in the plaque scores (p = 0.58) compared to the toothbrush group (p = 0.007). A notable rise in gingival score was observed within the miswak group (p < 0.001), whereas no significant change was noted within the toothbrush group (p = 0.52). Conclusions: Over a two-week period, miswak was successful in controlling dental plaque; however, gingival scores were higher, which could be attributed to the aggressive use of miswak. With proper training, the use of miswak has the potential to contribute positively to gingival health, particularly in regions where it is readily accessible and affordable. [ABSTRACT FROM AUTHOR]

Aim: This qualitative study sought to assess the influence of cultural factors and family on oral health behaviour of 12‐ to 15‐year‐old adolescents from the socially disadvantaged population. Design: A qualitative design was developed with focus group discussions (FGDs) among 12‐ to 15‐year‐old adolescents. Four focus groups (n = 32 participants) were created from a selected sample to capture oral health beliefs and practices, oral health‐seeking behaviour along with other relevant information. Focus group discussions were audio‐recorded, transcribed verbatim and translated. Data were analysed thematically and structural coding was applied. Results: Three key themes that emerged from FGDs were importance of oral health; role of family in oral health behaviour; and beliefs influencing access, prevention and treatment of oral diseases. Cultural background, family values and beliefs were imperative in moulding the behaviour of adolescents towards oral health. The use of traditional oral hygiene aides was a norm in this population. Conclusions: Findings of the study provide greater insights into the authoritative role of family and cultural barriers in the uptake of dental services. The study also highlights the potential value of qualitative research and emphasizes the need to integrate oral health‐associated cultural beliefs and attitudes of the adolescents towards a wider evidence base.

Background: Dietary and oral hygiene habits among integrated migrant cultural minorities can vary and could impact susceptibility to caries. Aim: This study aimed to assess and compare the oral health status of Tibetan schoolchildren living in the Tibetan settlement of Bylakuppe, India, stratified by type of residence. Design: A descriptive cross‐sectional study was conducted among Tibetan schoolchildren attending nine schools in the Bylakuppe region. Results: The study population consisted of 916 children aged 5–17: 702 (76.6%) living in secular houses (LSH) and 214 (23.4%) living in monasteries (LM). The prevalence of dental caries was 70.9%, and the mean value of decayed, missing, filled teeth for mixed and primary dentition (DMFT*; dmft) of LSH children (1.56 ± 2.34/1.74 ± 2.66) was higher than of LM ones (1.14 ± 2.34/0.83 ± 2.80; p <.001). DMFT for LM children (1.46 ± 2.04) was slightly higher than for LSH children (1.38 ± 1.96; p >.05). Among the sample, 99.1% had a good simplified Oral Hygiene Index (OHI) and LM children showed higher rates of good values (99.5% vs. 98.2% in LSH children). Most children needed preventive/routine dental treatment, whereas 16.6% needed urgent dental treatment. In 4.5% of children, oral mucosal lesions were present. Conclusion: This study confirms the high need for dental treatment in the children of the Tibetan settlement investigated. [ABSTRACT FROM AUTHOR]

Background: Halitosis in children implies psychosocial repercussions. Risk factors associated with this condition are unclear, and detection methods are inaccurate. Aim: To quantify the levels of sulfur‐like compounds in children with asthma and healthy children from a novel validated assay, and to establish the risk factors related to halitosis. Design: One hundred and twenty‐eight individuals (63 healthy and 65 asthmatic) from 3 to 17 years of age were tested using a passive colorimetric sensor to measure the levels of sulfur‐like compounds in breath and saliva. Information was collected on oral hygiene habits, gingival and dental health, breathing type, and dental malocclusion. Results: The mean values of hydrogen sulfide were 4.0 ± 6.8 and 19.7 ± 12.2 ppbv (parts per billion in volume) in the control and asthmatic groups, respectively (p <.001). The presence of higher concentrations of sulfur compounds was significantly associated (p <.05) with the presence of gingival inflammation, tongue coating, dental plaque, mouth breathing, hypomineralization, age, tongue brushing, and the use of dental floss. Conclusion: The level of sulfur in breath and saliva was significantly higher in patients with asthma. These results can serve as a precedent to raise awareness among paediatricians and parents about oral hygiene care in children and adolescents. [ABSTRACT FROM AUTHOR]

Background: Obesity and dental caries are two major global public health concerns. There have been conflicting reports about the relationship between obesity and dental caries. This study intends to examine the link between obesity and dental caries across the five regions of Saudi Arabia. Methods: The study involved 380 participants, which was a cross-sectional survey, with an age range of 6 to 14. We distributed a self-reported questionnaire to assess the participants body mass index (BMI) and caries (dmft/DMFT). In this study, descriptive analysis, student t-test, one-way analysis of variance (ANOVA), and multiple linear regression analysis were used. Results: The study comprised 380 respondents, consisting of females (60.8%) and males (39.2%), with a mean age of 9.1 years and mean BMI of 26.3. The prevalence of caries among the study respondents was 66.6% (Table 2), and this prevalence was higher among females (67.5%), those who consumed sugar more than six times (77.5%), those who brushed their teeth once per day (80.3%), those who used no dental floss (68.4%), those who did not use mouthwash or rinse (68.4%), and those in the east and center regions (100%). The obese possess a statistically significant (P < 0.05) higher mean dmft/DMFT (dmft = 8.00 and DMFT = 6.00). Furthermore, BMI had a negative influence on the DMFT score (b = −0.01, P = 0.776), which was not statistically significant. Conclusion: Participants categorized as obese demonstrated a notably higher mean dmft/DMFT in comparison to their non-obese counterparts. Although BMI showed a negative impact on the DMFT score, this association did not reach statistical significance. [ABSTRACT FROM AUTHOR]

Background: This study aimed to assess the effect of malocclusion severity according to the Index of Treatment Need (IOTN) on oral health (dental caries and gingivitis), and its correlation with socioeconomic status (SES) in Iranian adolescents. Methods: This descriptive cross-sectional study was conducted on adolescents between 10 and 16 years in Tehran city, who underwent clinical dental examination. The Dental Health Component (DHC) of the IOTN was used to assess the severity of malocclusion. The DMFT index was calculated to assess dental caries, and the gingival index (GI) was calculated for gingival health assessment. For oral hygiene assessment, the Oral Hygiene Index-Simplified (OHI-S) was calculated, and a questionnaire was used. Results: Totally, 306 adolescents participated in this study. The frequency of IOTN grades was 88 (28.8%), 89 (26.1%) ,49 (16%), 60 (19.6%), and 29 (9.5%) for grades 1 to 5, respectively. The multinomial logistic regression showed that by an increase in OHI-S score, the odds of having IOTN grade 4 compared to grade 1 increased. Postgraduate parental level of education decreased the odds of having IOTN grade 4 compared to grade 1. Furthermore, there was an inverse correlation between oral hygiene practice and the odds of having IOTN grade 5 compared to grade 1. Conclusions: Malocclusion may hinder oral hygiene practice, and resultantly increase plaque accumulation. This risk may be amplified in children with lower SES, highlighting the need for preventive and educational oral health programs. [ABSTRACT FROM AUTHOR]

Background: The aim of the study is to evaluate the effectiveness of different toothbrushes in reducing gingival inflammation and dental biofilm removal in gingivitis patients with fixed orthodontic appliances. Methods: Following baseline clinical assessments, including the Turesky modification of the Quigley-Hein plaque index (TQHI), gingival index (GI), bleeding on probing (BOP), and probing pocket depth (PPD), all patients received nonsurgical periodontal therapy. Patients were then randomly assigned to one of three groups: conventional toothbrush (C-TB), orthodontic toothbrush (O-TB), or single-tufted toothbrush (ST-TB). Each group received tailored oral hygiene instructions based on their assigned toothbrush type. Clinical assessments were repeated and recorded in the first week, sixth week, and third month. Results: Thirty-six patients with a mean age of 23.14 ± 3.86 (18–32 years) participated in the study. All groups with twelve patients each demonstrated significant improvements in clinical parameters compared to baseline. In the sixth week, the O-TB and ST-TB groups showed significantly greater improvements in TQHI and BOP scores compared to the C-TB group (p < 0.05). By the third month, the ST-TB group maintained significantly lower TQHI and BOP scores, while the O-TB group's scores became similar to those of the C-TB group. ST-TB and C-TB groups had significantly lower GI scores than the O-TB group in all time points. Although the effectiveness of ST-TB was significantly higher than that of other toothbrushes, all toothbrushes demonstrated lower efficacy in the posterior region. Conclusions: The ST-TB was shown to be more effective in reducing gingival inflammation over three months, while it demonstrated similar efficacy to the O-TB in dental biofilm removal. Further research is necessary to substantiate these findings and to demonstrate the efficacy of this approach in promoting periodontal tissue health in patients with fixed orthodontic appliances. Trial registration: This study was registered with the National Library of Medicine Clinical Trials Registry Platform on 19/07/2024 as NCT06510179. [ABSTRACT FROM AUTHOR]

Background: Military personnel often face unique challenges in maintaining optimal oral health. This study investigated the oral health status, caries experience, and associated factors among a sample of Iranian soldiers, employing a structural equation modeling (SEM) approach to explore the complex interplay of socioeconomic and behavioral determinants. Methods: A cross-sectional study was conducted among 658 male soldiers aged 18–30 years from three military barracks in Fars province, Iran. Data were collected through a structured instrument and clinical oral examinations. The study employs the DMFT index, which measures caries experience based on decayed, missing, and filled teeth, along with the Simplified Oral Hygiene Index (OHI-S) to assess overall oral health status. Structural equation modeling was employed to analyze the complex relationships between socioeconomic factors, oral health behaviors, and oral health outcomes. Results: The mean DMFT score was 3.57 ± 5.91, and the mean OHIS score was 0.56 ± 1.42. SEM analysis revealed that socioeconomic status (SES) indirectly influenced DMFT and oral hygiene scores, mediated by drug use, oral hygiene practices, dietary sugar consumption, and dental visit frequency. Lower toothbrushing frequency was significantly associated with higher DMFT (Estimate = -0.064, p < 0.001) and OHIS scores (Estimate = -0.637, p < 0.001). Drug use (smoking, qalyan, alcohol) was linked to poorer oral health outcomes, while more frequent dental visits were associated with lower DMFT and OHIS scores. Conclusion: This study reveals the complex interplay between socioeconomic conditions, oral health behaviors, and oral health outcomes among Iranian soldiers. The findings highlight the need for targeted interventions to address modifiable risk factors and improve access to preventive dental care within military settings. Future longitudinal studies are warranted to elucidate further the causal pathways between these factors and oral health outcomes in military populations. [ABSTRACT FROM AUTHOR]

Background: Visceral Leishmaniasis (VL) is the most severe and fatal disease if left untreated. In people living with HIV/AIDS (PLHA), VL is considered an emerging opportunistic infection. The aim of this manuscript was to report a first case in Tunisia of a concomitant presentation of visceral and oral leishmaniasis in a patient LHA. A systematic review of the literature was performed according to PRISMA guidelines, as well. Case presentation: The patient, a 43-year-old heterosexual man, treated for HIV/AIDS was referred for macrocheilitis of the upper and lower lips. A noticeable nodular and painless swelling extending to the cheeks' mucosa was noted. The patient's poor oral hygiene was evident due to the presence of multiple dental caries. Histological analysis of the biopsied lower lip sample revealed the presence of numerous Leishmania amastigotes. The diagnosis of VL was clinically confirmed by the presence of a mild splenomegaly and pancytopenia and biologically by the identification of the parasite using PCR Lei and the species L. infantum involved using RFLP-PCR and culture. The treatment consisted of an intravenous administration of liposomal Amphotericin B (Ambisome®, 40 mg/kg/weight) for a period of 6 weeks. A favorable outcome was noted after one year with the resolution of clinical symptoms and a negative Leishmania blood PCR test. After 2 years, the patient remained asymptomatic but showed a positive Leishmania blood PCR test. Dolutegravir® was introduced in the patient's ART regimen. Conclusions: To the best of our knowledge, this is the first case report in Tunisia of atypical VL diagnosed through an uncommon oral location in an HIV/AIDS co-infected patient. Since VL is a severe and potentially fatal disease, it is essential for dentists to perform a thorough clinical examination and adopt a multidisciplinary approach in order to ensure an early diagnosis and an effective treatment outcome.

Background: This prospective study aims to investigate the comparative effects of clear aligners (CA) and traditional removable appliances (RA) on the cariogenic risk of patients in mixed dentition, focusing on the oral microbiome. Methods: 25 children were included and assigned into CA and RA groups. Supragingival plaque and saliva samples were collected, and clinical parameters including Decay-missing-filled teeth index (DMFT), Plaque Index (PI) and Gorelick Index (GI) were recorded before treatment (T0) and after 6-month follow-up (T1). DNA was extracted from supragingival plaque and saliva and analyzed via 16S rDNA gene sequencing. Results: Clinical parameters showed no statistically significant difference between groups at each time point or within group over time (p > 0.05). In both RA and CA groups, saliva exhibited significantly higher alpha diversity compared to supragingival plaque at T1, as indicated by the significantly higher Chao1 and Shannon indexes (p < 0.05). Regarding beta diversity, significant difference was observed in saliva and supragingival plaque samples between T0 and T1 within group RA (p < 0.05, Adonis), whereas no such significance was noted in the CA group (p > 0.05, Adonis). At the genus level, Lactobacillus exhibited a statistically significant increase in saliva and supragingival plaque of group RA from T0 to T1 (p < 0.05), and an increasing trend in the group CA without statistical significance (p > 0.05). At T1, Lactobacillus levels were comparable between groups, whereas species-level analysis revealed distinct cariogenic species. Conclusion: Both clear aligners and traditional removable appliances resulted in elevated cariogenic risk of patients in mixed dentition at the microbial level. Distinct alterations in cariogenic species were observed to be induced by various orthodontic appliances. [ABSTRACT FROM AUTHOR]

Background: Oral health is so important for the adolescent age group that the World Health Organization has listed oral health as a lifelong prerequisite for maintaining public health; Therefore, this research was carried out with the aim of the effect of educational intervention based on self-efficacy theory on the promotion of behaviors related to oral health of adolescents through mobile application. Methods: In this clinical trial, 80 adolescents aged 13–15 years from Shushtar city were selected using a random cluster sampling method and assigned to either the test or control group. The data collection tools included a standard questionnaire for measuring Oral health behavior (awareness, attitude, behavior) and a standard questionnaire for measuring self-efficacy (self-efficacy in brushing teeth, self-efficacy in using dental floss, and self-efficacy in visiting the dentist), as well as demographic characteristics. Training was provided to the test group via a mobile application for 3 weeks. During the intervention, the control group did not receive any training. Questionnaires were distributed in both groups immediately after the intervention, as well as one month and three months post-intervention, and data were collected. In accordance with research ethics, at the end of the study, the educational content was provided to the control group. Collected data were analyzed using SPSS 22 software and Mann-Whitney and Friedman non-parametric tests. Results: The findings showed that the educational intervention through the mobile application was effective in improving the average scores of awareness, attitude, self-efficacy in brushing teeth, flossing, visiting the dentist, and the behavior of adolescents regarding oral health behaviors, and this statistical difference was significant compared to before the educational intervention (P < 0.05), while no change was observed in the control group (p > 0.05). Conclusion: Considering that adolescents aged 13–15 years are the age of starting behavioral habits, including oral health behaviors, and on the other hand, their interest in using technology and virtual spaces is high, it is suggested that part of the education of this age group should be designed and implemented in the platform of mobile application.

Objectives: This study evaluated the impact of self-management interventions based on the COM-B model on peri-implant conditions in older adults with periodontitis. Materials and methods: The patients were randomly divided into two groups: Group 1 (control group) received only an oral health education (OHE) pamphlet. Group 2 (test group) performed a self-management intervention based on the COM-B model. Each patient was examined for the most inflammatory implant. The measurement parameters included self-efficacy, self-management ability, and clinical indicators such as probing depth (PD), bleeding on probing (BOP), modified gingival index (mGI), modified plaque index (mPI), and peri-implant mucositis severity score (PMSS). The data was collected at baseline, 4, 8, and 12 weeks. Results: 42 patients underwent testing for 3 months. After 12 weeks, the improvement of self-efficacy, self-management ability, and the reduction of BOP, mPI, and PMSS in the test group was significantly higher than in the control group. Conclusion: The study suggests that self-management interventions based on the COM-B model can enhance the self-management ability of older adults with periodontitis and reduce peri-implant inflammation. This method is more effective than distributing OHE pamphlets. Trial registration: The randomized controlled clinical trial was registered on Chinese Clinical Trial Registry (No. ChiCTR2400082660, Date: 03/04/2024). [ABSTRACT FROM AUTHOR]

Objective: To compare the effectiveness of different oral hygiene education strategies on periodontal health in fixed orthodontic patients in a one-month period: assistant-led instruction, social media-based education, and custom-made software. Methods: Sixty orthodontic patients from Mashhad University of Medical Sciences' Dentistry School were randomly assigned into three groups. Each group received oral health education differently: via assistant instruction, educational videos on social media, or a researcher-designed software for Android smartphones. After a month, participants' oral health was evaluated using the plaque index (PI) and the gingival index (GI). Results: Assistant-led education group demonstrated the highest PI (1.26 ± 0.70) and GI (0.92 ± 0.67), while the software group reported the lowest indices (PI = 0.68, GI = 0.46 ± 0.46). The social media group's measurements fell between these extremes (PI = 0.89 ± 0.75, GI = 0.60 ± 0.52). Significant group differences were found for both PI and GI (P = 0.028 and P = 0.047, respectively). Pairwise comparison revealed significantly lower PI and GI in the software group compared to the assistant group. No significant differences were found between the social media and other groups. Conclusion: Our results suggest that the use of specially designed software could be the most effective strategy for improving oral hygiene in orthodontic patients. Meanwhile, traditional assistant-led education showed the least effectiveness. The study supports the potential benefit of utilizing digital tools, such as bespoke software and social media, in oral health education for orthodontic patients. Trial registration: The study was registered in the Iranian Registry of Clinical Trials (IRCT) database with the identification code IRCT20200609047705N2 in 13.07.2021. [ABSTRACT FROM AUTHOR]

Background: In the socio-dental approach, the integration of normative oral health-related quality of life (OHRQoL) and behavioral propensity measures should be considered when assessing treatment needs and planning oral services. Therefore, this study aimed to evaluate the relationship between oral health impacts attributed to malocclusion and normative and self-perceived orthodontic treatment needs in adolescent patients and to determine the clinical, sociodemographic, and behavioral factors affecting their OHRQoL. Methods: This cross-sectional study was conducted using a convenience sample size of 105 adolescent patients aged 11–14 years who were referred to the Orthodontics Clinic in the Faculty of Dentistry, Istanbul. Data were collected using clinical examinations and a self-reported questionnaire, including the condition-specific Child Oral Impact on Daily Performances (CS-COIDP) attributed to malocclusion and sociodemographic, clinical, and behavioral factors. The index of complexity, outcome, and need (ICON), gingival index, and Decayed, Missing, Filled Teeth index was used to assess oral health status. Descriptive statistics and bivariate and multivariate regression analyses were used for the data analyses. Results: A total of 70 patients (66.7%) reported at least one impact. Furthermore, 47% of the adolescents had very difficult and difficult complexity grades. The most affected performances were "emotional (52.4%) and smiling (40%)". No significant differences were found in the total CS-COIDP scores according to caries experience; however, the gingival status was associated with the total OHRQoL. Lower tooth brushing frequency, increased malocclusion complexity, and subjective treatment need were the most important predictors of worse OHRQoL, accounting for 39.3% of the variance in the scores. (R2 = 0.422; p < 0.001) Conclusions: Oral health professionals should consider oral behaviors, malocclusion complexity, and subjective treatment need when planning orthodontic treatment plans. Integrating ICON, CS-COIDP, and behavioral assessment will help identify adolescents who should be prioritized for treatment. [ABSTRACT FROM AUTHOR]

Background: Oral Health Literacy (OHL), defined as an ability to obtain, understand, and apply information related to oral health, plays a crucial role in promoting effective oral health outcomes and behaviors. Given the pressing need to enhance oral health among older adults, this scoping review aims to summarize the impact of OHL on oral health behaviors and outcomes in this population. Methods: The authors performed an electronic search up through July 22, 2024. Among the 2,226 articles identified, the authors included studies in which the investigators evaluated the association between OHL and oral health behaviors or outcomes restricted to individuals aged 60 years and older. Thematic analysis was used to develop the domain for oral health behaviors or outcomes. Results: Among the 10 studies analyzed, significant correlations were identified between OHL and various oral health indicators, including periodontitis, the number of remaining teeth, dental prosthesis use, oral hygiene, oral health-related quality of life among men, as well as dissatisfaction with oral health (p < 0.05). However, the results were conflicting across the studies, indicating variability in the strength and nature of these associations. Additionally, OHL was shown to significantly influence oral health-related behaviors, especially the tooth brushing frequency (p < 0.05). Conclusions: This review highlights a scarcity of studies addressing OHL in older populations, suggesting that OHL has been deprioritized in efforts to improve oral health for this vulnerable group. Key gaps include the need for age-appropriate OHL assessment tools, stronger evidence linking OHL to specific oral health behaviors and outcomes, and the integration of OHL into broader health initiatives and research in older group. These areas are critical to advancing our understanding and improving oral health outcomes among older adults. [ABSTRACT FROM AUTHOR]

Background: The environment can alter the homeostasis of humans and human microbiota. Oral health is influenced by high altitude through symptoms of periodontitis, barodontalgia, dental barotrauma, and a decrease in salivary flow. Microbiota and inflammatory state are connected in the oral cavity. This study aimed to explore the effect of acute high-altitude exposure on the salivary microbiome and inflammatory indicators. Methods: Fifteen healthy expeditioners were subjected to oral examination, recording the plaque index (PII), gingival index (GI), the simplified oral hygiene index (OHI-S), and the number of teeth; unstimulated saliva samples were collected at an altitude of 1191 m (T1) and 4556 m (T2). TNF-α, sICAM1, ROS, and the oral bacterial species Porphyromonas gingivalis (Pg) and Fusobacterium nucleatum (Fn) were quantified. Results: At T2, slCAM, TNF, and ROS increased by 85.5% (IQR 74%), 84% (IQR 409.25%), and 53.5% (IQR 68%), respectively, while Pg decreased by 92.43% (IQR 102.5%). The decrease in Pg was greater in the presence of low OHI-S. The increase in slCAM1 correlated with the reduction in Fn. Individuals with high GI and OHI-S had a limited increase in TNF-α at T2. Conclusion: Short-term exposures can affect the concentration of pathogenic periodontal bacteria and promote local inflammation. [ABSTRACT FROM AUTHOR]

Introduction: Head and neck squamous cell carcinoma (HNSCC) ranks sixth among cancers in the world, and the 5-year survival rate ranges from 25% to 60%. The risk factors for HNSCC are primarily smoking, alcohol consumption and human papillomavirus (HPV). Data indicate that 15–20% of cancers are caused by infectious agents, 20–30% by smoking and 30–35% by unhealthy lifestyles, diet, lack of physical activity and obesity. Dysbiosis is a microbiome imbalance, which promotes oncogenesis by intensifying inflammatory processes and affecting the host's metabolism. Profiling the microbiome in various types of cancer is currently the subject of research and analysis. However, there is still little information on the correlation of the microbiome with HNSCC and its impact on oncogenesis, the course of the disease and its treatment. Objective: The aim of the study was to prospectively assess risk factors with assessment of the impact of the microbiome on the risk of squamous cell carcinoma of the larynx. The study included a group of 44 patients diagnosed with squamous cell carcinoma of the larynx and 30 patients from the control group. Results: In the control group, bacteria of the normal microbiome dominated—the genus Streptococcus, Gemella, Neisseria and Kingella. In the group of patients with laryngeal cancer, Prevotella, Clostridiales and Stomatobaculum were found significantly more often. Porphyromonas, Fusobacterium, Lactobacillus, Actinobacteria, Actinomyces and Shaalia odontolytica were also found at a higher percentage in the study group. Analyzing the phylum, Firmicutes dominated in the control group; there were statistically significantly more of them than in patients from the study group. Bacteroides and Bacillota were found significantly more often in patients with laryngeal cancer. Conclusions: The importance of the microbiome in oncology has been confirmed in many studies. Independent risk factors for laryngeal cancer were primarily a lower number of Firmicutes in the microbiome, but also an increased leukocyte level above 6.52 × 103/mm and a decreased total protein level below 6.9 g/dL. Prevotella, Clostridiales, Stomatobaculum, Porphyromonas, Fusobacterium, Lactobacillus, Actinobacteria, Actinomyces and Shaalia were considered to be the bacteria contributing to the development of laryngeal cancer. Streptococcus, Gemella, Neisserie and Kingella were considered to be protective bacteria. Moreover, the study confirmed the significant impact of smoking, alcohol consumption and poor oral hygiene on the development of laryngeal cancer. The microbiome, its identification and manipulation may constitute a breakthrough discovery for improving the diagnosis and oncological therapy of laryngeal cancer, and also of the entire group of HNSCC. Profiling the microbiome may allow for personalized therapy related to its modification. Assessing the microbiome of patients diagnosed with cancer may provide an opportunity to predict treatment response and effectiveness. [ABSTRACT FROM AUTHOR]

Background: Individuals with Autism Spectrum Disorder (ASD) frequently encounter increased levels of anxiety and display resistant behaviors during dental examinations, which negatively affects their oral care and maintenance. This study employed a cross-sectional design to evaluate the impact of virtual reality (VR) intervention on the anxiety and level of cooperation in children and adolescents with ASD during dental examinations. Methods: A total of 140 participants diagnosed with ASD, aged from 4- to 18-years-old, were selected from two specialized ASD management centers in Riyadh/Saudi Arabia. The participants were randomly allocated into either the control group or the VR group. Control group participants were subjected to a conventional dental examination, while the VR group utilized VR intervention to immerse themselves in a simulated natural and soothing environment. The Venham anxiety and behavior scale (VABS) was utilized to measure anxiety levels, while the Frankl behavior rating scale (FBRS) was employed to assess the level of cooperation. Data were analyzed using a Mann–Whitney U test with a significance level of p < 0.05. Results: The baseline anxiety and level of cooperation between the groups were comparable (p > 0.05). During the dental examination, the VR group had significantly reduced anxiety scores (2.48 ± 1.76) compared to the control group (1.50 ± 1.74) (p < 0.001). Regarding the level of cooperation, the VR group exhibited significantly greater levels of cooperation (3.41 ± 0.96) than the control group (2.86 ± 1.03) (p = 0.002). Conclusions: These findings suggest that VR intervention is a successful technique for decreasing anxiety and enhancing cooperation among children with ASD during dental examination. Integrating VR technology in dental environments can potentially improve the dental experience and results for children diagnosed with ASD. [ABSTRACT FROM AUTHOR]

Background: Toothbrushing is important for maintaining oral health and preventing periodontal disease. However, the association between toothbrushing and systemic diseases remains unclear in adolescence. In this study, the association between dental self-care (frequency and duration of toothbrushing) and systemic diseases/disorders in adolescents was examined. Methods: We conducted a retrospective review of mandatory medical questionnaires administered during legally mandated freshman medical checkups between 2017 and 2019 at the University of Tokyo, Japan. Out of 9376 total responses, 9098 cases involving individuals under the age of 20 were included in the analysis. Respondents were classified into three groups based on their daily toothbrushing frequency: "1 time or less", "twice", and "3 times or more". For the duration of each toothbrushing session, they were classified into three groups: "1 min or less", "2–3 min", and "4 min or more". A statistical analysis was performed by Pearson's χ2 test and multinomial logistic regression analysis. Results: Regarding frequency of daily toothbrushing: The χ2 test showed no significant relationship between frequency of toothbrushing and 17 systemic diseases/disorders. A multivariate analysis found that gingival bleeding and sex were independent factors. The risk of gingival bleeding decreased dramatically with increased frequency of toothbrushing (odds ratio (OR): 0.428; 95% confidence interval (CI), 0.366–0.501; p < 0.001). Regarding the amount of time spent on toothbrushing: The χ2 test showed atopic dermatitis and arrhythmia were significantly associated with the duration of toothbrushing (p = 0.032 and p = 0.016, respectively). In the multivariate analysis, atopic dermatitis, gingival bleeding, and sex were independent factors regarding the duration of toothbrushing; longer brushing time was associated with a lower risk of atopic dermatitis (OR: 0.731, 95% CI: 0.578–0.924, p = 0.009) and a lower risk of gingival bleeding (OR: 0.643, 95% CI: 0.567–0.729, p < 0.001). Conclusions: Dental self-care was most strongly associated with gingival bleeding, while the risk of atopic dermatitis was found to increase with shorter toothbrushing times. The results suggest that dental self-care during adolescence is important not only for oral health but also for general health. [ABSTRACT FROM AUTHOR]

Purpose: No information on the fluoride concentration in orthodontic tooth pastes sold in Iraq is presently available. The goal of this investigation was to establish and compare the fluoride content of five orthodontic tooth pastes offered in Iraqi drugstores, as well as testing the null hypothesis that entails the consistency of fluoride concentration measured over time may not deviate from the labelled amounts. Methods: Laboratory investigation on five brands of orthodontic tooth pastes namely Wisdom, Ortho Kin, Kemphor Ortho, VITIS Orthodontic and G.U.M. Ortho to determine the fluoride concentration in triplicate using a fluoride ion-selective electrode at two time points. A paired sample t-test and a one-sample t-test were used to determine the difference between the fluoride concentration reported on the tube and the observed value in both time intervals. Results: Initially all brands exhibited levels exceeding 1000 ppm with mean concentrations as follows; Wisdom Orthoclean (1355 ppm) Ortho Kin (1349 ppm) Kemphor Ortho (1361 ppm) VITIS Orthodontic (1348 ppm) and G.U.M. Ortho (1494 ppm) which were significantly lower than stated on the tube. After one month, a significant drop was noticed in the levels of fluoride in all tooth pastes (p-value ≤ 0.05). Conclusions: The fluoride concentration in orthodontic tooth pastes decreases over time and does not reach the levels stated on the packaging. It is advisable to recommend tooth pastes that retain their effectiveness even after being opened for some time. [ABSTRACT FROM AUTHOR]

Aim: A workshop on concordance and oral hygiene was held in February 2024. To address the topic, a systematic review aimed at investigating the effectiveness of motivational interventions in improving oral hygiene and focusing on periodontal clinical indices outcomes was designed. Materials and Methods: A comprehensive literature search was conducted across PubMed and Scopus electronic databases to identify relevant articles published up to 2024. Inclusion criteria encompassed studies comparing motivational interventions targeting oral hygiene behaviours, with a focus on periodontal clinical indices. Twelve articles meeting the eligibility criteria were selected for analysis. Quality assessment and data extraction were performed systematically. Results: The synthesis of findings from the selected studies revealed a consistent positive effect of motivational interventions on periodontal clinical indices. These interventions encompassed various strategies, including educational sessions, personalized feedback and motivational interviewing. Improvement in indices such as plaque index (PI), gingival index (GI) and periodontal probing depth was observed following motivational interventions, despite the variety of motivational protocols employed. Conclusion: Motivational interventions are effective in enhancing oral hygiene practices and improving periodontal clinical indices. Tailored motivational approaches can serve as valuable tools in promoting oral health behaviours among individuals, potentially reducing the risk of periodontal diseases. Further research is warranted to explore the long‐term sustainability and scalability of motivational interventions in diverse populations and settings. [ABSTRACT FROM AUTHOR]

Objectives: Recent studies have highlighted the association between problematic screen exposure (PSE) in preschool children and various health issues. This study aims to determine the relationship between PSE and oral/dental health as well as parafunctional oral habits in this population. Methods: Healthy children aged 3 to 6 years who visited the pediatric dentistry outpatient clinic were included in the study. PSE was evaluated using the parent-reported 'Seven-in-Seven-Screen-Exposure Questionnaire'. An intraoral examination was conducted to record the number of decated, missing, and filled teeth, along with scores from the International Caries Detection and Assessment System II (ICDAS II), as well as dental plaque and gingival indices. Results: A total of 210 mother–child pairs were included in the study, comprising 70 pairs with PSE and 140 pairs without PSE. The sociodemographic characteristics, frequency of daily tooth brushing behaviors, use of children's toothpaste, and regular dental examinations were statistically evaluated between the PSE and non-PSE group (p > 0.05). Additionally, there was no statistically significant difference between the groups in terms of having abnormal oral habits (p > 0.05). In the PSE group, the median scores for gingival and plaque index were significantly higher (p = 0.011 and p = 0.006, respectively). The median number of decayed teeth was significantly higher in the PSE group (p = 0.039). Conclusions: Turkish preschool children with PSE were found to have a significantly higher likelihood of experiencing poor oral health. Consequently, it is essential to conduct oral health examinations for Turkish preschool children exhibiting PSE. The study may have clinical implications for the evaluation of preschool children with problematic media use within dental practice. [ABSTRACT FROM AUTHOR]

Children are susceptible to infections due to frequent participation in school group activities and their often-suboptimal hygiene practices. Frequent infections in children affect school attendance, academic performances, and general health. The effectiveness of school-based hygiene-related intervention programmes need to be informed by updated high-quality synthesised evidence. In this systematic review, we searched PubMed and Cochrane CENTRAL for randomised and non-randomised interventional studies that evaluated school-based hygiene-related interventions. We assessed risk-of-bias (Cochrane risk-of-bias 2 tool), performed random-effect meta-analysis (RevMan 5.4) and rated certainty-of-evidence (GRADE). Thirty-nine trials (41 reports), published from 2011 to 2024 from 22 countries were included. Twenty-three studies contributed data for meta-analysis. All school-based interventions were compared with standard curriculum and demonstrated very low to low certainty-of-evidence due to study methodological limitations and imprecision. Hand-body hygiene interventions may improve knowledge, attitudes and practices (SMD 2.30, 95%CI 1.17 to 3.44, 6 studies, 7301 participants), increase handwashing practices (RR 1.75, 95%CI 1.41 to 2.17, 5 studies, 5479 participants), and reduce infection-related absenteeism (RR 0.74, 95%CI 0.66 to 0.83, 5 studies, 1017852 observations). Genital hygiene interventions may improve attitude (SMD 6.53, 95%CI 2.40 to 10.66, 2 studies, 2644 participants) and practices (RR 2.44, 95%CI 1.28 to 4.68, 1 study, 1201 participants). However, intervention effects on oral hygiene appeared mixed, with worsening of the oral hygiene score (SMD 3.12, 95%CI 1.87 to 4.37, 2 studies, 652 participants) but improved dental hygiene (SMD -0.33, 95%CI -0.53 to -0.13, 3 studies, 4824 participants) and dental caries scores (SMD -0.34, 95%CI -0.52 to -0.16, 4 studies, 2352 participants). Limited evidence suggests that interventions targeting hand-body and genital hygiene practices may improve knowledge, practices, and infection-related absenteeism. However, the effects on oral hygiene intervention appeared mixed. Future research should strengthen randomisation and intervention documentation, and evaluate hygiene-related behaviour, academic performances and health outcomes. [ABSTRACT FROM AUTHOR]

Background: Nosocomial infections pose a global health threat, with Ventilator-Associated Pneumonia (VAP) emerging as a prominent hospital-acquired infection, particularly in intensive care units (ICU).VAP is the commonest form of pneumonia in ICUs, contributing significantly to morbidity and mortality rates, which can reach around 30%. Despite the substantial impact of VAP on healthcare, there is a lack of data on adherence to VAP prevention protocols in our hospital. Consequently, this study aims to assess the adherence to ventilator-associated pneumonia care bundles in critical care units at a comprehensive specialized hospital in northwest Ethiopia. Methods: A hospital-based prospective observational study was conducted from July 3, 2022, to January 7, 2024. All adult patients who were on mechanical ventilators for more than 48 h during the study period were included. Data were collected using the Institute of Healthcare Improvement VAP prevention standards as checklists via direct observation and chart review. The data were entered and analyzed using SPSS version 20. Results: A total of 300 surgical and medical ICU patients were observed. Among the patients, 66.3% were from the medical ICU. In terms of admission reasons, 22.3%, 15.7% and, 12% were attributed to infections excluding respiratory origin, respiratory disorders, and other causes, respectively. The rate of compliance with all components of the bundle was 70%. A 100% adherence rate was observed for the prophylaxis for peptic ulcer and deep vein thrombosis (DVT). The lowest adherence rate was observed in the practice of oral hygiene with 0.5% chlorhexidine solution (0%) followed by humidification with heat and moisture exchangers (23.3%). Endotracheal tube cuff pressure measurement and use of endotracheal tubes with subglottic suction were not applicable. Conclusion: The study revealed suboptimal compliance with the VAP care bundle, indicating unsatisfactory overall practice. Specific attention is warranted for subglottic suction, cuff pressure measurement, humidification, oral care with chlorhexidine, and sedation vacation. [ABSTRACT FROM AUTHOR]

Background: Plaque biofilm is a major etiologic factor of periodontitis, and its effective removal prevents or ameliorates the disease. However, toothbrushing alone does not sufficiently clean the interdental area, and additional interdental cleaning is required to completely remove the plaque from this locale. This cross-sectional study aimed to assess the association of interdental cleaning on the prevalence of periodontitis in a large urban Thai adult cohort. Methods: Interdental cleaning data were retrieved from a dental survey of 1,743 employees of the Electricity Generating Authority of Thailand (EGAT) in 2019. The Centers for Disease Control and Prevention/American Association of Periodontology (CDC/AAP) periodontal case definitions were applied. The participants were subdivided into two groups as those with or without periodontitis depending on their oral health status assessed by calibrated professional examiners. The proportion of subjects who performed interdental cleaning was assessed through a self-reported questionnaire by frequency (daily/ ≥ 1 per week/ none) and profile (correct/ incorrect) of interdental cleaning. Then, the association between interdental cleaning and periodontitis was calculated using logistic regression analysis controlling for the common risk factors of periodontitis such as age, sex, education, smoking, and diabetes. Results: Participants who performed interdental cleaning on a daily basis and ≥ 1 per week were 27.5% (95% CI: 25.4, 29.6) and 29.1% (95% CI: 27.0, 31.3), respectively while the remainder did not practice. Of those who used interdental cleaning, about one-half focused on sites with food impaction. There was a significant 44% lower prevalence of periodontitis (adjusted odds ratio of 0.56 (95%CI: 0.40, 0.79) in the cohort with a frequent and correct group. Conclusions: Our data indicate an inverse association between interdental cleaning and periodontitis, particularly in those who routinely adhered to it. Regular interdental cleaning is likely to have a salutary effect on oral health. Trial registration: The study was registered retrospectively in Thai Clinical Trials Registry, Registration number: TCTR20240817005, on 17 Aug 2024 (https://www.thaiclinicaltrials.org).

Background: Toothbrushing is the most commonly used method to physically remove dental plaque. However, there are many areas of the mouth that are difficult to reach with a toothbrush. The type of toothbrush is a critical factor influencing the effectiveness of oral care. The purpose of the study was to evaluate a toothbrush with a thin head, slender-neck and super-tapered bristles to target hard-to-reach areas in the oral cavity for reducing dental plaque and gingivitis. Methods: This crossover study included 58 adults aged 20 years and older. All participants were randomly assigned to use test and control toothbrushes (the latter had a normal head and round bristles) for two 4-week phases. Participants brushed their teeth twice daily in their habitual manner. At the start and end of each phase the Silness-Lӧe plaque index (PI), Lӧe -Silness gingival index (GI) and bleeding-on-probing index (BOP) were assessed and performed plaque fluorescence tests using quantitative light-induced fluorescence technology. Results: After using the test toothbrush, PI, GI and BOP decreased by 25%, 30% and 48%, respectively (P < 0.05). For the rearmost molars, PI, GI and BOP decreased by 18%, 26% and 47%, respectively (P < 0.05). For the implants, GI and BOP decreased by 31% and 57%, respectively (P < 0.05). The plaque fluorescence tests indicated that after using the test toothbrush, the dental plaque area for the anterior teeth and the simple plaque score for the rearmost molars decreased by 25% (P < 0.05) and 14% (P = 0.527), respectively. Conclusions: The test toothbrush was markedly better than the control toothbrush at reducing dental plaque and gingivitis. In particular, the test toothbrush produced an excellent reduction in dental plaque and gingivitis for the rearmost molars and the implants.
