Purpose: To evaluate the survival and success rates of short (> 6 mm and = 8.5 mm) implants after at least 2 years of functional loading. Implants were assessed using clinical parameters such as marginal bone loss (MBL), pocket depth (PD), keratinized mucosa width (KMW), bleeding on probing (BoP), and the peri-implant condition (mucositis or periimplantitis). Any correlations between clinical parameters were analyzed. Materials and Methods: This observational and retrospective study included 114 posterior maxillary and mandibular implants placed in 27 women and 38 men with a mean age of 68.04 ± 9.07 years. Patients included in the study had received at least one short implant between 2001 and 2013, such that each implant was in occlusal function for at least 2 years by 2015. Patients with only long (= 10 mm) implants, patients with any systemic condition, and smokers were excluded from the study. PD, KMW, periimplant condition, BoP, and MBL were the clinical parameters assessed in the study. Data on prosthesis type (single or splinted) and implant features were also obtained. All data were submitted to analysis via Mann-Whitney unpaired test, with a significance level of P < .05. Spearman correlation coefficient was also measured to verify the negative or positive correlation. Results: The mean follow-up time was 74.08 months, and mean implant success and survival rates were 87.63% and 94.74%, respectively. There were 6 implant failures (5.26%). A total of 66 (59.46%) prostheses were screw-retained implant-supported restorations, and 45 (40.54%) were cemented. A total of 93 (86.49%) short implants were splinted to another implant, and 15 out of 111 (13.51%) restorations were single implants. Keratinized mucosa was missing around 43 (39%) implants, whereas PD was measured to be between 0 and 3 mm in 64.86% of implants and = 4 mm in 31.53% of implants. MBL was = 1.5 mm in 71.17% of cases and > two-thirds the length of the implant in 2.71% of cases. Mucositis and peri-implantitis were found in 22.52% and 7.21% of implants, respectively. The correlation coefficient showed a positive result for PD and MBL (0.11; P = .368) and negative results for PD and KMW (-0.42; P = .002) and KMW and MBL (-0.19; P = .183). Conclusions: Within the limitations of this study, it is possible to conclude that short implants are a feasible treatment option for dental rehabilitation. They are considered an excellent alternative to complex procedures and have high survival rates after at least 2 years of follow-up, with compatible peri-implant local tissue response. Moreover, a significant negative correlation between KMW and PD was observed. [ABSTRACT FROM AUTHOR]

This study investigated the association between prior incarceration length and edentulism among US adults 55 years and older. Analyses explored indirect factors such as wealth, smoking status, mental health, and chronic health conditions that may explain this relationship. In addition, the study analyzed how associations between incarceration and edentulism vary by race and ethnicity. The authors used data from the 2012-2014 Health and Retirement Study (unweighted N = 11,630; weighted N = 72,872,877) to assess the relationship between incarceration duration and edentulism through multivariable logistic regression. The Karlson-Holm-Breen method evaluated indirect effects, and multiplicative interaction terms examined variations by race and ethnicity. Net of control variables analyses showed a positive association between having been incarcerated for more than 1 month and higher odds of edentulism. However, this association was rendered statistically nonsignificant after accounting for wealth, current smoking status, mental health, and chronic disease. Collectively, wealth and smoking explained approximately 60% of the association between prior incarceration length and edentulism. Racial moderation models indicated that longer incarceration times increased edentulism likelihood in non-Hispanic Whites specifically. To the authors' knowledge, this is the first study on the association between prior incarceration length and edentulism among older adults. Study findings indicated the relationship between incarceration and edentulism was explained by higher wealth and current smoking status. These findings highlight the need for adequate access to oral health care services for formerly incarcerated older adults to improve oral health and enhance their overall health and quality of life [ABSTRACT FROM AUTHOR]

Background: Edentulism is considered the ultimate sign of oral health disease burden. It is a common and frequent clinical disease, mostly seen in the elderly, which has been reported to be closely associated with many diseases. While physical activity is known to benefit many chronic diseases, the relationship between the volume of physical activity and edentulism remains unclear. Materials and methods: The CHARLS provided the data for this study. A total of 6,480 participants were enrolled in this study, of whom 46.02% were male and 53.98% were female. The edentulism was defined according to self-report and physical activity volume can be represented by metabolic equivalents. Multiple logistic regression, smooth curve fitting, threshold effects analysis, and Cox regression models were used to explore the relationship between physical activity volume and edentulism. Results: In the fully adjusted model, physically active participants had a 24% lower risk of edentulism compared to those who were physically inactive. Then, we subdivided participants with adequate physical activity into four levels: 600 ≤ PAV < 1200; 1200 ≤ PAV < 1800; 1800 ≤ PAV < 3000; and PAV ≥ 3000. We found that the risk of developing edentulism was lowest and statistically significant at the level of 1,800-3,000 MET-minutes/week physical activity volume (OR = 0.41; 95% CI, 0.24–0.69, p < 0.001). A U-shaped relationship between physical activity volume and edentulism with an inflection point of 2514 (MET-minutes/week) was observed. The results of the longitudinal study also confirm the benefits of physical activity volume with edentulism, participants with adequate physical activity volume had a 21% lower risk of developing edentulism than participants with inadequate physical activity volume (HR = 0.79; 95% CI, 0.67–0.94, p = 0.008). Conclusions: This study reveals a U-shaped relationship between physical activity volume and edentulism. Physical activity reduces the risk of developing edentulism in middle-aged and older populations, but it is important to control the appropriate volume of physical activity. [ABSTRACT FROM AUTHOR]

Objectives: To evaluate the changes in oral health-related quality of life [OHRQoL] before and three months after complete denture oral rehabilitation using the Geriatric oral health assessment index [GOHAI] in Pakistani elderly edentulous patients. Methods: In this descriptive case series study a total of 80 edentulous patients were recruited from Islamic International Dental Hospital, Islamabad, Pakistan from November 2021 to April 2022. The OHRQoL was evaluated twice by using the GOHAI- Urdu version. First, before getting the complete denture, and subsequently after three months of using a prosthesis. The data were analysed using SPSS-23. Pre and post-comparison were done by t-test. Moreover, the ANOVA test was utilized to assess the socio-demographic variables-GOHAI score and association. Results: The mean GOHAI scores increased significantly from 22.9 (SD = 3.01) at baseline to 28.1 (SD = 5.59) after three months (P = 0.001), reflecting an overall increase of 5.2 points. At baseline, the ability of the patient to swallow comfortably was found to have the highest mean GOHAI score of 3.02 (SD=1.24) and after three months of complete denture insertion, the same questionnaire item further improved with the highest mean GOHAI score of 3.43 (SD=1.05). The socio-demographic characteristics-based comparison of mean pre and post-insertion GOHAI scores suggested a statistically significant difference (p=0.001). Conclusion: The OHRQoL in elderly edentulous patients improved after complete denture delivery, and a significant improvement was noted in most GOHAI domains. [ABSTRACT FROM AUTHOR]

Objectives: The present study aimed to systematically review the studies comparing the accuracy of intraoral scan (IOS) and conventional implant impressions (CI) in completely edentulous patients. Materials and Methods: Electronic searches were performed in PubMed, Embase and Cochrane CENTRAL up to December 1, 2023. Clinical studies and in vitro studies reporting the accuracy of digital full arch impressions were included. The primary outcome is the 3‐dimensional deviations between the study reference models. A risk of bias assessment was performed for clinical studies. A stratified meta‐analysis and a single‐armed meta‐analysis were conducted. Results: A total of 49 studies were included, with 8 clinical studies and 41 in vitro studies. For comparison between IOS and conventional impressions, studies were categorized into two groups based on the different measurement methods employed: RMS and CMM. In studies using RMS, the result favored the IOS in the unparalleled situation with the mean difference of −99.29 μm (95% CI: [−141.38, −57.19], I2 = 81%), while the result was opposite with the mean difference of 13.62 μm (95% CI: [10.97, 16.28], I2 = 26%) when implants were paralleled. For different brands of IOS, the accuracy ranged from 76.11 μm (95% CI: [42.36, 109.86]) to 158.63 μm (95% CI: [−14.68, 331.93]). Conclusions: Accuracy of intraoral scan is clinically acceptable in edentulous arches, especially for unparalleled implants. More clinical studies are needed to verify the present finding.

Aim: To (i) assess the prevalence, incidence, and burden of severe periodontitis and edentulism in 2021, and (ii) forecast their rates in 2050. Methods: Prevalence, incidence, and Years Lived with Disability (YLDs) for severe periodontitis and edentulism in 2021 were gathered globally, covering 204 countries, seven super regions, and 21 regions from the Global Burden of Disease (GBD) 2021 study. Prevalence, incidence, and YLDs due to periodontitis and edentulism to 2050 were projected using mixed‐effects models with the socio‐demographic index as the main covariate. Results: In 2021, over 1 billion people were affected by severe periodontitis (1066.95 million; 95% UI: 896.55–1234.84), with a global age‐standardized prevalence of 12.50% (10.53–14.49). South Asia had the highest prevalence rate, at 17.57% (14.73; 20.14). Edentulism affected 353 million people globally (300.60–416.20), resulting in an age‐standardized prevalence of 4.11% (3.50; 4.83). The highest edentulism prevalence was found in Latin America and the Caribbean, at 7.39% (6.44; 8.39). By 2050, more than 1.5 billion people (+44.32%) are projected to have severe periodontitis, and over 660 million (+84.40%) to be edentulous. In the same year, 19.67% (130.23 million) of the edentulous people worldwide will be located in China. Severe periodontitis is expected to move up one position, and edentulism nine positions, among the most impactful Level 4 diseases/conditions affecting YLDs worldwide by 2050. Conclusion: Severe periodontitis and edentulism remain major public health challenges in 2021, with the number of affected individuals projected to rise significantly in the coming decades.

Edentulism (total tooth loss) can be managed with four possible options: no prosthetic replacement, conventional complete dentures, implant-retained overdentures (removable), or implant-supported bridgework (fixed). Selection of these choices is influenced by social, medical, anatomical, technical, and economic factors. The care team involved in the decision-making process (be it patients, clinicians and occasionally commissioners of services) should be aware of the different treatment options and their potential impact on the patient's quality of life (QoL). The cost effectiveness of this impact can also be evaluated. Knowledge of the life-long sequelae of edentulism will also help practitioners guide patients in their treatment planning decisions when they may be approaching an edentulous state, preparing them for the challenges that may lie ahead. This paper aims to address the impact that edentulism has on QoL and the treatment options, focusing on the patient perspective. [ABSTRACT FROM AUTHOR]

Introduction: With increasing age, patients experience a reduction in immunity and an increase in systemic illnesses. These factors significantly contribute to the occurrence of candidiasis in the oral cavity. New approaches to treating and preventing a wide range of oral disorders may become possible through host immunity modulation. Natural agents are preferred for complete denture wearers to prevent candidiasis, which is one of the leading causes of denture stomatitis. Aim: To assess the efficacy of herbal oral rinses (Triphala) and probiotics against Candida species in denture-wearing patients. Materials and Methods: This randomised double-blinded study clinical study was conducted in the Department of Prosthodontics at MM College of Dental Sciences and Research, Mullana, Ambala, Haryana, India, from August 2022 to January 2023. Ethical clearance was obtained and 60 patients were randomly divided into two groups (n=30): Group-A (Probiotics group) and Group-B (Triphala group). Sample collection was performed at baseline and after an 8-week experimental period. The collected samples were inoculated in Sabouraud Dextrose Agar with Chloramphenicol and incubated for 48 hours at 37°C±2°C in a Biological Oxygen Demand (BOD) incubator. The number of Candida colonies was scored and counted using a Digital Colony Counter, reported as Colony-forming Units (CFU) at baseline and after eight weeks. Data analysis was conducted using the Wilcoxon matched-pair test for comparisons within groups and the Mann-Whitney U-test for pair-wise comparisons (p0.05) was observed between the two groups, both rinses proved effective against Candida species in denture-wearing patients. However, the mean reduction in CFUs was significantly higher for Triphala (p-value=0.021). Conclusion: Both probiotics and Triphala showed a significant reduction in CFU after eight weeks of use. However, Triphala was more effective in reducing Candida compared to probiotics. Therefore, it can be considered an efficient agent for denture-wearing patients against Candida species.

Oral health and general health are closely linked and dependent in humans. The total disappearance of teeth leads to the loss of proprioceptive control systems, the modification of the entire tissue system and therefore great psychological fragility. Pre-prosthetic surgery consists of restoring the osteo-mucosal tissues to allow the installation of a prosthesis. The objective: was to assess the need for pre-surgical prosthetic preparation for the totally edentulous at the CHU-CNOS of Bamako. Method and materials: This was a prospective, descriptive study extending over a period of 8 months (from January 1 to August 31, 2021). Patients seen at the removable prosthesis service for a consultation in whom a diagnosis of edentulism was made constituted the study population. We carried out an exhaustive recruitment of totally edentulous people received at the service for the completed removable prosthesis who agreed to participate in the study. The data were collected using an individual survey form and analyzed with SPSS version 20.0 software. Result: A total of 50 patients were registered, including 14 men or 28% and 36 women or 72%. The sex ratio was 0.38 in favor of women. The 60 to 69 age group was the most represented with 19% and the average age was 56 years. The demand for prosthetic restoration for aesthetic and functional purposes represented the reasons for consultation in 46%, 44% of cases and pain in 10% of cases the most expressed concern by patients. Oral hygiene was average 64%, good at 20% and poor at 16%. Tooth extraction represented 70% of cases, without surgery 20% of cases and osteotomy 10% of cases as pre-surgical prosthetic treatment. The ridge was poorly resorbed at 40%, moderately resorbed at 30%, very resorbed at 20% and the ridge was negative at 10%, 50% of patients did not wear a prosthesis, 34% of patients wore partial removable prostheses and 16% wore removable total prostheses. Among our patients 66% had normal frenulums, 22% had short frenulums and 12% had wide frenulums. Conclusion: This study made it possible to highlight the real needs in pre-surgical prosthetic preparation. Among these needs, multiple tooth extraction remains the most common pre-prosthetic surgical procedure.

The management of the aesthetic parameter represents an important factor in the integration of removable prostheses. The current major social interest in beauty has made patients more and more demanding with regard to their appearance. [1] The main objective of this study was to assess the aesthetic expectations of patients with removable prostheses at the CHU-CNOS in Bamako. Our prospective and descriptive study having collected 78 patients was carried out over a period from March 2, 2019 to March 9, 2020 at the removable prosthesis department of the CHU-CNOS in Bamako. The female sex represented 55.1% with a sex ratio of 0.65. Removable prosthetic rehabilitation mainly concerned young adults aged 21-41 (41%) Aesthetics was the main reason for rehabilitation most represented with 60.3% of cases. The white tooth was the most requested dental shade with 70.5% of cases Bonded teeth were the most represented in our patients with 71.79% of cases. Pink gum was the shade most requested by our patients with 43.6% of cases. Obtaining a personalized prosthesis in harmony with the facial framework, giving the illusion of naturalness and restoring the smile to patients is the objective to be achieved.

The aim of our study was to assess the need for pre-prosthetic and pre-implant therapeutic management of the edentulism complications to impair the biomechanical stability of the future hybrid prostheses. Materials and Method. 150 subjects with partial extended or complete edentulism (mean age 61,54 +/- 8,99 yrs.), eligible for hybrid prosthetic therapy were assessed in Clinical Learning Base of Faculty of Dental Medicine, U.M.F. “Grigore T.Popa” Iasi.. Patients were divided in two groups: Group A (n=96): patients with partial reduced or extended edentulism that were eligible to hybrid prosthetic therapy, retained by fixed teeth-supported prosthetic restoration; Group B (H-PFR/IP) (n=54): patients with total or subtotal edentulism that were eligible to implant-supported hybrid prosthetic therapy, retained by fixed implant-supported prosthetic restorations. The need for non-surgical and surgical procedures in the pro-prosthetic and pro-implant stage was assessed at global level as well as related to the patients’ variables within each study group. Results. Significantly higher percentage of patients in Group B requested alveoloplasty (77,8%), alveolar bone addition (83,3%), frenectomy (22,8%), and complex therapy of the temporo-mandibular disorders (94,4%), when compared to Group A (20.8%, 49,0%, 54,2%, respectively) (p

Background: A specific type of transitional denture called a Cu-Sil denture provides a therapy alternative for people who have a lot of natural teeth still in place and do not want to have them extracted. This is particularly salutary for cases where people may feel tone-conscious about the negative impact of tooth loss on their appearance and emotional well-being. Purpose: The purpose of this case report is to provide prosthetic rehabilitation for a partially edentulous patient while conserving the remaining natural teeth and their supporting structures. Case: With only three teeth (12, 13, and 14) remained in the maxillary arch, a 63-year-old man complained to the department of prosthodontics that he had difficulties speaking and eating since he had been missing both upper and lower teeth for a period of five years. Case management:This case report represents a simple method to fabricate a Cu-Sil denture in a partially edentulous patient. Conclusion: Cu-Sil dentures present a promising alternative for partially edentulous patients, offering a method to preserve and support the remaining natural teeth while providing effective prosthetic rehabilitation. The relining material, silicone, functions as a cushion to support the remaining natural teeth. Additionally, the use of a chairside soft-tissue liner in the basic removable partial denture helps to stabilize and retain the existing natural teeth.

This study aimed to assess the prevalence of edentulism and tooth loss in the Slovenian elderly population, along with the associated risk factors, and investigate the association between systemic and oral health.

Objectives: To examine the longitudinal relationship between edentulism, nutritional intake, and the progress of multimorbidity among older Americans. Methods: We used data from the Health and Retirement Study (2006–2018), a longitudinal survey of older Americans that has collected data biennially since 1992. Edentulism was assessed in 2006 while nutritional intake was assessed in 2013. Multimorbidity was indicated by five self-reported chronic conditions: diabetes, heart conditions, lung diseases, cancer, and stroke. Individuals with two or more conditions at baseline were excluded from the analysis. Nutritional intake was calculated by summing 10 nutrients (protein, vitamins C, D, B12 and E, calcium, zinc, polyunsaturated fatty acids, folate, and ß-carotene). Structural equation modelling (SEM) was used to examine the nutritional pathway between edentulism (2006) and the increase in multimorbidity from 2006 to 2018. Results: The number of individuals included in the analysis was 3463. The incidence of multimorbidity between 2006 and 2018 was 24.07%, while the percentage of edentate participants in 2006 was 16.42%. The mean total nutrition in 2013 was 4.50 (4.43, 4.55). The SEM analysis showed that edentulism was negatively associated with nutritional intake {estimate −0.15 (95%CI: −0.30, −0.01)}. A negative association was found between total nutrition and multimorbidity {estimate −0.008 (95%CI: −0.01, −0.002)}. Age, wealth, and smoking were included in the analysis and had statistically significant associations with multimorbidity. Conclusion: The analysis demonstrated a longitudinal association between edentulism, nutritional intake, and the progress of multimorbidity. [ABSTRACT FROM AUTHOR]

• The present study reaffirmed the correlation between functional dentition and cognitive performance by examining data obtained from a sample of 3127 participants. • A sequential relationship was identified, wherein denture usage, depressive symptoms, and social participation were found to mediate the impact of edentulism on cognitive function. • The findings of our study suggest a pressing need to prioritize older adults with complete tooth loss, with timely interventions addressing denture usage, alleviation of depressive symptoms, and enhancement of social engagement showing promise in preventing cognitive decline. The objective of this study was to investigate the chain mediating effects of depressive symptoms and social participation between functional teeth and cognitive function based on the biopsychosocial model. Data from the 2018 China Health and Retirement Longitudinal Study were analyzed. The findings revealed a favorable connection between the lack of edentulism and cognitive function, persisting even when accounting for the mediating factors of denture usage, depressive symptoms, and social participation. Furthermore, the study identified six indirect pathways in this relationship. The present study has substantiated the correlation between edentulism and cognitive function, thereby proposing that interventions aimed at denture usage, depressive symptoms, and social participation could potentially serve as preventive measures against cognitive decline in elderly individuals afflicted with edentulism. This underscores the significance of addressing these factors to alleviate cognitive decline. [ABSTRACT FROM AUTHOR]

The need for non-surgical and surgical procedures in the pro-prosthetic and pro-implant stage was assessed at global level as well as related to the patients' variables within each study group. Results. Significantly higher percentage of patients in Group B requested alveoloplasty (77,8%), alveolar bone addition (83,3%), frenectomy (22,8%), and complex therapy of the temporo-mandibular disorders (94,4%), when compared to Group A (20.8%, 49,0%, 54,2%, respectively) (p <0.001**). Conclusions. Most patients with subtotal or complete edentulism need pre-implant therapeutic interventions (alveoloplasty, alveolar bone addition, frenectomy, and/or treatment of the temporo-mandibular disorders) for the improvement of the biomechanical stability of the future hybrid prostheses. The need for these procedures in the pre-prosthetic stage was significantly lower for patients with extended partial edentulism eligible for removable dentures retained by fixed implant-supported bridges.

Objective: To investigate the association between oral health status and all‐cause mortality in older adults using prospective cohort study design. Setting and participants: In total, 12 809 adults aged ≥70 years (54.3% females) were participants of the ASPREE Longitudinal Study of Older Persons (ALSOP). Methods: Participants self‐reported the presence of natural teeth and oral health status. The association of self‐reported oral health, edentulism and the integrative measure of the two with all‐cause mortality were explored using the Cox‐regression models adjusted for age, gender, socio‐economic status, health‐related behaviours, weight status, aspirin and polypharmacy. Hazard ratios (HRs) and 95% confidence intervals (CIs) were reported. Results: In total, 22.2% of participants reported edentulism and 13.8% had fair/poor oral health. After adjustment for confounders, risk of all‐cause mortality was higher among those with edentulism (vs. no edentulism) HR (95% CI) 1.43 (1.18, 1.73); and those with edentulism and reporting poor/fair oral health HR (95% CI) 1.69 (1.02, 2.82), or with no edentulism but reporting poor/fair oral health HR (95% CI) 1.46 (1.19–1.80) vs. no edentulism and reporting good/very good/excellent oral health. No association was observed between self‐reported oral health alone and all‐cause mortality. Conclusions: The risk of all‐cause mortality was 69% higher among older adults reporting both edentulism and poor/fair oral health compared with those with teeth and more favourable self‐reported oral health. © 2023 Australian Dental Association.

This case report of a 45-year-old patient at initial presentation shows an illustration of the limitations of periodontal maintenance therapy and subsequent implant prosthetic therapy. In close consultation with the patient, treatment strategies were adopted to maximize the preservation of prognostically questionable teeth. Eight years later, the patient had a highly atrophied maxilla that could be successfully restored with implants. This was achieved with 2 zygoma implants and 2 anterior conventional implants, which were immediately loaded according to the All-on-4 concept and immediately provided with a definitive prosthetic restoration. The case report demonstrates to the general practitioner that using zygoma implants in such constellations may offer a solution to achieve a fixed, rapid, and financially acceptable prosthetic rehabilitation.

Objectives: This study evaluated the prevalence, diameter and location of the mandibular incisive canal (MIC) and the transition pattern and anterior loop length (ALL) of the mental canal and compared these values between dentate and edentulous mandibles. Methods: A total of 187 cone-beam computed tomography (CBCT) images of mandibles, namely, 100 images of dentate mandibles and 87 images of edentulous mandibles, were obtained. CBCT data related to the incisive canal and mental canal were analyzed by one examiner. Results: The prevalence of the MIC was 75∼78 %, showing no difference based on laterality or the presence of teeth. The ALL significantly differed depending on the presence of teeth as well as sex. The presence of teeth affected the size of the MIC in the female group, and the diameter of the MIC in the edentulous group was significantly narrower than that in the dentate group. The diameter of the MIC was significantly greater in males than in females in the edentulous group. Meanwhile, the location of the MIC in the male group depended on the presence of teeth at each measuring point, and the MIC was significantly closer to the lower border of the mandible in the female group than in the male group at all measuring points except at 0 mm. Conclusions: This study indicated that the presence of teeth significantly affects the type of transition of the mental canal, the ALL, and the diameter and location of the MIC. Additionally, sex could be a factor affecting MIC location, MIC diameter and anterior loop length.

Purpose: Education is well-known as a determinant of oral health and dental behaviours in high-income countries, but much less is known for countries with lower incomes. This study aimed to identify the extent to which education affects oral health and dental behaviours in Indonesia. Materials and Methods: This study used data from the Indonesian Basic Health Survey 2013. From this nationally representative sample of 945,057 people 5-100 years old, a series of mixed-effects Poisson regression models that accounted for sampling weights estimated the effect of educational attainment on edentulism, dental care utilisation, and toothbrushing behaviour. Results: Consistent educational gradients were found for all outcomes and across all model specifications. People without a formal educational degree had a 1.03 (95% CI: 1.03-1.04) times higher risk of not utilising any dental care, a 3.15 (95% CI: 2.47-4.02) times higher risk of being edentulous, and a 15.6 (95% CI: 12.76-19.02) times higher risk of having low toothbrushing frequency than people having a university degree or higher. Conclusions: Stark and consistent educational gradients were observed in the dentate status, dental services utilisation, and toothbrushing in Indonesia. Educational inequalities were much larger for toothbrushing behaviours than for dental care utilisation. Intervention points for health policy should urgently prioritise public health interventions to promote overall educational attainment, preventive services, and dental care targeted at those with lower educational attainment.

Introduction: Providing complete denture therapy to patients with atrophic residual alveolar ridges is challenging, because these patients suffer ongoing resorption of the denture foundation; regardless of contemporary treatment options, physiologically optimal denture contours and appropriate denture tooth arrangement should be achieved to maximize prosthesis stability, comfort and function for patients. One of the methods used to achieve the stability is the neutral zone technique. Aim: It is in this zone that the natural dentitions lie and this is where the artificial teeth should be positioned. This article describes a preview of faciolingual positioning of denture teeth along with a novel approach of recording the neutral zone. Conclusion: The neutral zone is the area where the displacing forces of the lips, cheeks and tongue are in balance. Physiologic recording of the neutral zone aids in stability to the prosthesis.

Objective: To evaluate patient esthetics and functional satisfaction with complete denture therapy. Study Design: Cross-sectional observational study. th Place and Duration of Study: The study was conducted at Lahore Medical and Dental College from 10 February 2023 to 10 August 2023. Materials and Methods: Sixty-seven edentulous patients who have undergone complete denture therapy of tooth losses using complete denture for at least six months were enrolled. Patients' satisfaction was recorded having variables regarding socio demographic features and questions regarding esthetic and functional satisfaction of complete denture. Results: Forty-four patients (65.7%) have satisfied esthetics whereas 23 (34.3%) patients have no esthetics satisfaction. Forty patients (59.7%) were functionally satisfied, and 27 patients (40.3%) were not functionally satisfied. 89.5% patients were between 6-12 months and 7 (10.4%) patients were between 13-20 months of duration of use of denture. Conclusion: Patients appeared to be largely satisfied with their dentures, indicating that patient happiness is a key factor in the success of denture delivery.

Dental implants present a viable treatment option for the replacement of partial and full edentulism. Since their initial creation in the 1960s, implants have proceeded to become popular among both patients and dental practitioners due to their high success and survival rates. Despite the promising results, there remains some patient hesitation toward the acceptance of implant treatment. This hesitance mainly stems from four key factors that have greatly influenced patient decision-making: financial barriers, awareness and cultural sensitivity issues, treatment timespan, and the varying possible complications. Financial barriers generally arise from the lack of insurance benefits for the surgical aspect of treatment and the differing socioeconomic statuses of the patient population. Though dental implants have become more widespread, public knowledge of the matter is still insufficient. Patients may have altered conceptions of the procedure due to insufficiently credible information sources. In addition, dental practitioners need to consider the cultural restrictions that may be existent for some patients. The long timespan of the dental implant treatment, including healing time, may result in some patients opting for fixed or removable prostheses, which have comparatively shorter treatment spans. Biomechanical overload, infection, and inflammation are varying types of complications that alter osseointegration, ultimately leading to many complications, such as peri-implantitis. These universal barriers may hinder patient acceptance of implant treatment. However, as dental health care professionals, it is important to understand this hesitance and help mitigate these obstacles through patient education and continual reassurance and support.

ABSTRACTBackground Masticatory dysfunction and periodontitis are independently linked to cognitive decline. This article aims to highlight the individual and common roles that periodontitis and tooth loss play in cognition. Specifically, we aim to summarize the behavioral effects on learning and memory that result from each pathology, explore mechanisms that may explain these effects, and review the commonalities between the two.Methods The PubMed database was used to implement searches of relevant clinical studies on the correlations between edentulism and cognitive decline as well as periodontitis and cognitive decline. Additional searches were done to investigate animal studies that provided behavioral and mechanistic findings to explain these relationships. The clinical and animal studies were summarized and analyzed in this review to reveal the commonalities and differences between these comorbidities.Results The clinical studies summarized in this review report significant correlations between both periodontitis and partial/full edentulism with cognitive decline. The behavioral and mechanistic findings in animal model studies are summarized to support the cognitive effects. Both in vivo and in vitro studies have identified key pathogens, molecules, or cellular pathways that contribute to a more comprehensive understanding of the pathophysiologic processes that link different types of oral disease to cognitive brain function.Practical Implications The correlation between oral disease and cognitive impairment has been well established but further exploration of the molecular and cellular mechanisms underlying these relationships can provide therapeutic implications and stress the importance of oral health and preventative care.AbbreviationsAD: Alzheimer’s Disease; AFT: animal fluency test; BOP: bleeding on probing; BGI: biofilm-gingival interface; CAL: clinical attachment loss; CDT: clock drawing test; CERAD: Consortium to Establish a Registry for Alzheimer’s Disease word learning test; CNS: central nervous system; CP: chronic periodontitis; DSST: digital substitution test; IL-1β: interleukin 1β; IL-6: interleukin 6; LC: locus coeruleus; MMP: matrix metalloproteinase; MMSE: Mini-Mental Status Examination; MoCA: Montreal Cognitive Assessment; MRI: Magnetic Resonance Imaging; MWM: Morris water maze; NO: nitric oxide; PDL: periodontal ligament; PISA: periodontal inflamed surface area; PP2A: protein phosphatase 2A; RABL: radiographic alveolar bone loss; RANKL: Receptor activator of nuclear factor-κB ligand; SCT: spatial copying task; TLR4: toll-like receptor 4; TNF-α: tumor necrosis factor α; Vmes: Mesencephalic trigeminal nucleus.

The rapid growth of the older adult population in the United States and their increased risk of edentulism make it essential to analyze trends and factors associated with edentulism. Data were obtained from the Behavioral Risk Factor Surveillance System from 2012 through 2020. US- and state-level trend lines were reported. Multiple logistic regression analyses were used to evaluate the association between self-reported complete edentulism and demographic characteristics, chronic diseases, smoking status, and health insurance status. Multiple imputations were used to address the missing data. A total of 771,513 (weighted n = 50,410,576) participants were included in the study. There was a significant (P =.021) downward trend in the prevalence of edentulism from 2012 (16.36%) through 2020 (13.54%). Having less than a high school education, being a smoker, being non-Hispanic Black, having an annual household income less than $75,000, and having chronic conditions, including diabetes, myocardial infarction, arthritis, depression, and stroke, were significantly associated with complete edentulism. Despite a decrease in prevalence of edentulism, disparities based on race, income, and education still exist. Edentulism is associated with chronic diseases in older adults. Public health initiatives should be aimed at reducing the impact of edentulism and improving overall quality of life among older adults. Community health programs allocating resources to improve access to affordable care, reducing precursors to edentulism, expanding dental coverage, and promoting oral and general health awareness are vital components of these efforts.

This case report documents the successful rehabilitation of a 78-year-old female patient who had been edentulous for 15 years. Despite residing in a remote area of Jammu and Kashmir (J&K), where access to dental care was limited, the patient's son, a bank employee, sought out specialized treatment for his mother's dental condition. After consultation and careful consideration, a treatment plan involving immediate loading of dental implants was implemented, providing the patient with fixed provisional teeth within 72 hours. This report highlights the importance of comprehensive assessment, interdisciplinary collaboration, and customized treatment planning in achieving successful outcomes, particularly in challenging cases.

Aim Methods Results Conclusion To explore the association between oral conditions and their interaction with salt taste disability among American adults.Data from the 2013–2014 NHANES cycle were used (n = 2373). The exposures were periodontitis, defined by the 2017 EFP‐AAP classification, dental caries, missing teeth, and edentulism, as per the DMF‐T index, and xerostomia. The outcome was salt taste disability, objectively assessed. Covariates included sex, age, educational level, poverty index, obesity, diabetes, smoking, alcohol consumption, and medications related to mouth dryness. Weighted multivariable logistic regression modeling was used to evaluate the relationship between oral conditions and their interaction and salt taste disability.Participants who reported xerostomia were more likely to have salt taste disability (OR 2.42; 95%CI 1.44–4.07), especially those older than 60 years (OR 3.63; 95%CI 1.72–7.63). Among participants aged 40–59, xerostomia increased the chance of salt taste disability; however, the confidence interval included the null value. The interactions between xerostomia and edentulism increased the chance of salt taste disability.Oral conditions seem to influence the ability to taste salt. Dental professionals may help identify individuals with taste alterations and raise their awareness of the risk of systemic diseases that require the reduction of salt intake. [ABSTRACT FROM AUTHOR]

Edentulism can generate negative impacts on self-esteem, interpersonal relationships, and oral functions. Removable prostheses are commonly used for tooth replacement, but they may cause discomfort due to micromovements during mastication. Objective and quantifiable methods are needed to evaluate these micromovements. A pilot study was conducted to determine the micromovements in removable prostheses during mastication using a 3D electromagnetic articulography (EMA-3D) system. One elderly participant wearing lower removable prostheses and an upper total well-fitting removable prosthesis was studied. The EMA-3D system was used to record movements in three spatial planes. Peanuts were given as test food, and the participant was instructed to chew normally while recordings were carried out until feeling the need to swallow. Analyses of the upper total prosthesis show micromovements ranging from 0.63 ± 0.11 to 1.02 ± 0.13 mm. During simultaneous analyses of the upper prosthesis and lower partial prosthesis, interference was not observed. This pilot study demonstrated the feasibility of using the EMA-3D system to evaluate micromovements in removable prostheses during mastication. Further research is needed to evaluate a larger sample and assess the clinical implications of these micromovements. [ABSTRACT FROM AUTHOR]

Partial or total dental loss (edentulism) is associated with decreased quality of life. Chile has large socioeconomic gaps, which are also recognized in oral health, but it is not known how Edentulism has evolved throughout the country. The aim of this study was to determine the edentulism in people born during the 19th and 20th centuries in Chile, who died in the 20th century, and to compare it with current data from the Chilean Ministry of Health (MINSAL) to observe its evolution in the country. For this purpose, 60 3D models of skulls from the Subactual Osteological Collection of Santiago were analyzed (30 individuals per sex), in which the presence and absence of teeth in antemortem in the maxilla were analyzed. A high percentage of tooth loss was observed, with 65 % partial edentulism, a 30 % total edentulism, and only 5 % had complete dentition in this osteological collection. In addition, a significant decrease over time was found; in 2017, the percentage of complete dentition at the national level was 32.8 %. A higher frequency of edentulism was also found in females from the osteological collection, with a significant probability of twice as much edentulism as in males. However, this sex difference was smaller than those found in the current study. Our study is the first to compare edentulism in Chile in two different time periods, since, in addition to studying it in the 19th and 20th century, it is carried out with data from the present day and in line with previous research, reveals the importance of socioeconomic and sex variables for dental loss.

Abstract Background Oral disorders are still a major global public health challenge, considering their perpetuating and chronic nature. Currently, there is no direct index to measure the quality of care on a population scale. Hence, we aim to propose a new index to measure the quality of care for oral disorders worldwide. Methods We generated our database using the data from the Global Burden of Disease (GBD) study 2017. Among different variables such as prevalence, incidence, years lived with disability, and disability-adjusted life years, we utilised principal component analysis (PCA) to determine the component that bears the greatest proportion of information to generate the novel quality of care index (QCI) for oral disorders. Results Global QCI for oral disorders gradually increased from 1990 to 2017 (from 70.5 to 74.6). No significant gender disparity was observed during this period, and the gender disparity ratio (GDR) was considered optimal in 1990 and 2017. Between 1990 and 2017, the age-standardised QCI for all oral disorders increased in all the SDI regions. The highest QCI for all oral disorders in 2017 belonged to high-middle SDI countries (=80.24), and the lowest YLDs rate was seen in the low SDI quintile. In 1990, the quality of care in European, Central Asian, and Central and South American countries was in the lowest quintiles, whereas the North American, East Asian, Middle Eastern, and some African countries had the highest quality of dental care. Maynmar (=100), Uganda (=92.5), Taiwan (=92.0), China (=92.5), and the United States (=89.2) were the five countries with the highest age-standardised QCI. Nicaragua (=41.3), Belgium (=40.2), Venezuela (=38.4), Sierra Leone (=30.5), and the Gambia (=30.3) were the five countries with the least age-standardised QCI values. Conclusion The quality of care for all oral disorders showed an increasing trend on a global scale from 1990 to 2017. However, the QCI distribution was not homogenous among various regions. To prevent the exacerbation of imminent disparities in this regard, better attention to total tooth loss in high-income countries and prioritising primary healthcare provision in low-income countries are recommended for oral disorders.

Abstract Background The objectives of this study were to compare oral frailty (OFr) among edentate and dentate older adults living in long-term care facilities (LTCF) and to clarify how edentulism and oral disease burden (ODB) of dentate older adults are associated with OFr. Methods The population of this study comprised 94 edentate and 209 dentate residents in LTCF in Helsinki, Finland, who had previously participated in a nutritional study. The participants underwent a clinical oral examination. The dentate residents were further divided into three ODB groups based on asymptotic dental score. The edentate and different ODB groups were compared with each other regarding demographics and oral and medical findings. OFr was defined as ≥ 2 of following: having a diet of soft/pureed food, residue of food in the oral cavity, inability to keep the mouth open during examination, unclearness of speech, dry mouth. The association between OFr and edentulousness and various levels of ODB was analyzed by a multivariate logistic model. Results Participants with low ODB had significantly less OFr than their edentate peers (p = 0.009). Furthermore, the edentate and dentate with high ODB had similar odds for OFr. Conclusions Edentulousness and high ODB are equally harmful conditions and may predispose to OFr. This study suggests that maintaining healthy natural teeth and good oral health (low ODB) may protect against OFr. Trial registration The Ethics Committee of the Hospital District of Helsinki and Uusimaa approved the protocols for the nutritional status and oral healthcare studies and the merging of the data, including patient medical records (Register number HUS/968/2017).

Background: Oral health is a major global public health problem, but its risk factors have not been fully identified. The limited evidence suggests that AL may affect oral health conditions, but most of these studies focus only on middle‐aged western populations. Objectives: To examine whether allostatic load is associated with oral health conditions later in life among middle‐aged and older adults in China and there there is a correlation in both middle‐aged and older people. Materials and methods: Data were collected from the China Health and Retirement Longitudinal Study 2011–2018 (N = 10 890) and were analysed using logistic regressions for the overall sample and subsamples by age. Results: Results showed that higher inflammation load significantly increased the odds of edentulism (OR = 1.358, 95% CI = 1.020–1.809, p <.05). Higher metabolic load significantly increased the odds of denture use (OR = 1.375, 95% CI = 1.154–1.640, p < 0.001) and difficulty in chewing solid foods (OR = 1.100, 95% CI = 1.035–1.169, p <.01). These associations were manifested in older adults over 60 years of age, while in the middle‐aged subsample, the associations were not significant. Conclusion: The findings suggested that higher allostatic load was associated with poorer oral health conditions later in life. It is critical to lower allostatic load and improve oral health conditions, especially for older adults over 60 years of age. Prospective studies and intervention trials help to better understand whether allostatic load is causally linked to oral health. [ABSTRACT FROM AUTHOR]

Registration of the denture bearing area is an essential step for a successful rehabilitation of complete edentulism. Traditionally, it is performed using different materials and techniques, for the moment methods based on muscles functional molding being preferred. As a consequence of the development of digital techniques, a new possibility for the registration of supporting structures emerged. The digital impression uses intraoral camera and offers precise details of the denture bearing area, but without the possibility of the functional registration of the marginal area. For the moment, the association between the traditional and digital techniques seems to be the ideal solution for a perfect registration of the denture bearing area in edentulous patients.

In order to treat edentulous patients with fixed implant prosthesis, the final prosthesis form should be predetermined based on the anatomic structures of the arch, the opposing dentition, and the occlusal plane. The design and occlusion of the interim prosthesis can provide useful information when fabricating the definitive prosthesis. In this case report, scan data of the edentulous region and the interim prosthesis were superimposed through an intraoral scanning digital workflow. In this way, the interim prosthesis information was incorporated into the design of the final prosthesis. Furthermore, the interim prosthesis data acquired through intraoral scanning was utilized to plan the positions and angles of the implants based on the final prosthesis design. Surgical guides were used to accurately place the implants in the planned three-dimensional positions. In this case report, satisfactory esthetic and functional clinical outcomes were achieved through application of digital techniques. [ABSTRACT FROM AUTHOR]

In William Faulkner's As I Lay Dying (1930), Anse Bundren is portrayed as an unusual patriarch. He lacks the power and influence of the Faulknerian parental figure and shows no devotion to his dead wife and his children. With a toothless mouth, Anse is generally received as a lazy and selfish father who watches his children working while resting in the shade, steals his daughter's money to have a set of new teeth, inters the dead body of his wife, and finds a new Mrs. Bundren. Anse is one of the least attractive patriarchs in Faulkner's Yoknapatawpha. He is despised by his family and his community and frequently criticized by scholars. However, Anse Bundren is a victim of his own dental condition as the pain he has to endure due to his decayed teeth leaves him with psychological and physiological disorders. The aim of this essay is to do justice to Anse Bundren by analyzing his dentally-induced psychophysiological condition and unveiling the reasons behind his callousness and selfishness.

Background: A specific type of transitional denture called a Cu-Sil denture provides a therapy alternative for people who have a lot of natural teeth still in place and do not want to have them extracted. This is particularly salutary for cases where people may feel tone-conscious about the negative impact of tooth loss on their appearance and emotional well-being. Purpose: The purpose of this case report is to provide prosthetic rehabilitation for a partially edentulous patient while conserving the remaining natural teeth and their supporting structures. Case: With only three teeth (12, 13, and 14) remained in the maxillary arch, a 63-year-old man complained to the department of prosthodontics that he had difficulties speaking and eating since he had been missing both upper and lower teeth for a period of five years. Case management:This case report represents a simple method to fabricate a Cu-Sil denture in a partially edentulous patient. Conclusion: Cu-Sil dentures present a promising alternative for partially edentulous patients, offering a method to preserve and support the remaining natural teeth while providing effective prosthetic rehabilitation. The relining material, silicone, functions as a cushion to support the remaining natural teeth. Additionally, the use of a chairside soft-tissue liner in the basic removable partial denture helps to stabilize and retain the existing natural teeth. [ABSTRACT FROM AUTHOR]
