Objective: This prospective controlled study aimed to assess whether changes in mandibular incisor inclination during orthodontic treatment with fixed appliances affect gingival thickness (GT) and the width of keratinized gingiva (WKG), and having as reference an untreated group of participants., Materials and Methods: Forty consecutively recruited adult orthodontic patients and 40 untreated volunteers, matched for age and gender and selected from the same background population serving as controls, were included. Mandibular incisor inclination was measured in lateral cephalograms before treatment commencement (T0) and 1 month before fixed appliances' removal (T1). Gingival thickness was measured using an Ultrasound Device (US) and width of keratinized gingiva (WKG) using a standard periodontal probe within the frames of a full periodontal examination at T0, T1, and 1 year after bracket removal (T2), that is, at about 30 months from T1., Results: Nineteen females and 21 males in each group [mean age in years (range): intervention group 23.1 (16.8-43.3); control: 21.85 (18.2-43.9)] were analysed. Overall, change in incisor proclination [mean change in Incisor Mandibular Angle Plane-IMPA (ΔIMPA) was 6.35° (SD 5.08°)] was not associated with any significant change in soft tissue thickness and with alterations in WKG. The group receiving fixed appliances did not exhibit thickening or thinning of GT in comparison to the control group; the WKG was reduced in the intervention group in comparison to the untreated group, where it essentially remained unchanged (#41: coeff.: -0.29, P value: .1, 95% CIs: -0.65, 0.06; #31: coeff.: -0.51, P value: .01, 95% CIs: -0.88, -0.14)., Conclusions: Lower incisor proclination during orthodontic treatment does not appear to significantly alter GT and WKG, but orthodontic treatment, overall, leads to reduction of the WKG., (© The Author(s) 2025.

Objective: The aim of the current study was to examine possible associations between gingival thickness and other parameters, such as crown length and width, papilla height and patient's age and gender., Overview: This cross-sectional study included 238 consecutive white Caucasian consecutive patients in all stages of orthodontic treatment (before, in-course, and after orthodontic treatment). Measurements of gingival thickness were carried out at both central mandibular incisors, mid-facially on the buccal aspect of each tooth, and 2 mm apically to the free gingival margin, with an Ultrasound device. Each patient was scanned with an intraoral 3D scanner before gingival thickness evaluation, where papilla height, and central mandibular and maxillary incisor crown length and width were measured., Conclusions: Significant (positive) association between gingiva thickness and patient's age and gender were found, with thicker gingiva being observed in older individuals and males. However, no significant association were found between gingival thickness and crown length, crown width, or papilla height., Clinical Significance: Variations in soft and hard tissue architecture significantly impact the long-term aesthetic outcomes of periodontal therapy, prosthetic and implant restorations, and root coverage treatments. Accurately assessing gingival biotype phenotype during treatment planning is critical to prevent complications, particularly in aesthetically sensitive areas., (© 2025 Wiley Periodicals LLC.)

Purpose: The prevalence of gingival recession in orthodontically treated patients and the relative impact of retainer type on its occurrence remain poorly understood. The objective of this study was to investigate the association between previous orthodontic treatment and retainer type on the long-term prevalence of gingival recession and to evaluate the role of other patient-related factors, such as gender, age, smoking and gingival phenotype., Materials and Methods: We included subjects both with and without a history of previous orthodontics (at least 5 years post-treatment). The periodontal status assessment and the presence of gingival recession were recorded. A generalised estimating equation (GEE) logistic regression model was used to examine the effect of the mode of retention and tooth type on recession adjusted for age, smoking, gender and gingival phenotype., Results: A total of 251 individuals (mean age of 32 ± 9.43 years) were included. Ninety-nine (39.4%) had a history of orthodontics with an observation period of 15.7 years. Those undergoing orthodontics followed by fixed retention had the highest prevalence and magnitude of recession; a history of orthodontics was statistically associated with the occurrence of recession (odds ratio: 2.40; 95% CI: 1.52; 3.82; P 0.001). Both age and the presence of a thin gingival phenotype were significant predictors for recession (P 0.001). The adjusted probabilities of recession per tooth indicated that the mandibular central incisors had the highest probability for recession, with either a fixed or removable retainer., Conclusions: Based on this observational study, the provision of orthodontic treatment followed by removable or fixed retention had a bearing on the occurrence of recession. The aetiology of gingival recession is multifactorial with a thin periodontal phenotype, age and smoking history being risk factors, while mandibular central incisors are particularly susceptible.

Objectives: Increasing evidence indicates that the thickness of periodontal soft tissues plays an important role in various clinical scenarios, thus pointing to the need of further clinical research in this area. Aim of the present study was to assess gingival thickness at the mandibular incisors by translucency judgement with two different probes and to validate if these methods are comparable and applicable as diagnostic tools., Materials and Methods: A total of 200 participants were included; gingival tissue thickness was measured by judging probe translucency at both central mandibular incisors, mid-facially on the buccal aspect of each tooth using a standard periodontal probe and a set of color-coded probe, each with a different color at the tip, i.e. Colorvue Biotype Probe (CBP). Frequencies and relative frequencies were calculated for probe visibility. Agreement between the standard periodontal probe and the CBP was evaluated via the kappa statistic., Results: When the periodontal probe was visible, the frequency of CBP being visible was very high. Kappa statistic for the agreement between the standard periodontal probe and the CBP was 0.198 (71.5% agreement; p-value < 0.001) for tooth 41 and 0.311 (74.0% agreement; p-value < 0.001) for tooth 31, indicating a positive association of the two methods., Conclusions: An agreement that reached 74% was estimated between the standard periodontal probe and the color-coded probe at central mandibular incisors.  CLINICAL RELEVANCE: In the context of the present study, the two methods of evaluating gingival thickness seem to produce comparable measurements with a substantial agreement. However, in the 1/4 of the cases, the visibility of the color-coded probe could not assist in the categorization of the gingival phenotype., (© 2024. The Author(s).)

Objectives: To explore the efficacy of Hyaluronic acid as an adjunctive in treatment of gingival recessions (GR)., Materials and Methods: A systematic literature search was performed in several electronic databases, including Medline/ PubMed, Embase, CENTRAL and LILACS. Recession improvement was evaluated through multiple outcome variables. The Cochrane Risk of Bias tool and the ROBINS-I tool were used to assess the quality of the included trials. Weighted Mean Differences (WMDs) and 95% confidence intervals (CIs) between test and control sites were estimated through meta-analysis using a random-effect model for the amount of Relative Root Coverage (RRC)., Results: A total of 3 randomised studies were deemed as eligible for inclusion. Their data were also used for pooling the effect estimates. Overall analysis of RRC (3 studies) presented a WMD of 7.49% (p = 0.42; 95% CIs -10.88, 25.86) in favour of adjunctive use of hyaluronic acid during Coronally Advanced Flap (CAF) technique, although statistical significance was not reached. Statistical heterogeneity was found to be high (I 2  = 80%)., Conclusions: Within their limitations, the present data indicate that the local application of Hyaluronic acid does not lead to additional clinical benefits when used as an adjunctive to the treatment of GR with CAF. However, due to the high heterogeneity among the studies, additional well-designed RCTs are needed to provide further evidence on this clinical indication for the use of Hyaluronic acid., Clinical Relevance: In the frame of the current review, the adjunctive use of Hyaluronic acid does not additionally improve the clinical outcomes obtained during treatment of GR with CAF., (© 2024.

Background: Initial caries lesion (ICLs) adjacent to orthodontic brackets are the most common side effect of orthodontic treatment with fixed appliances. The reported prevalence is uncertain and varies considerably across studies, from 27% to 97%., Objectives: This paper was designed to evaluate and synthesize the available evidence on the prevalence and incidence rates of ICLs in relation to orthodontic treatment. Selection criteria: The review (Prospero protocol CRD42023412952) included randomized and non-randomized clinical trials of interventions, cohort studies, and cross-sectional studies, published after 1990 on the prevalence or incidence of ICLs during or after orthodontic treatment with fixed appliances. Search methods: Pubmed, Scopus, and Embase databases were searched from 1990 until 01 May 2023. The risk of bias assessment was performed with RoB 2 and ROBINS-I tool and the Joanna Briggs Institute Critical Appraisal Checklist. Data collection and analysis: The proportion of individuals with ICLs, reported as the number/percentage of individuals/teeth with ICLs or mean number of ICLs per subject, were used to synthesize results., Results: The search yielded a total of 468 papers; 21 studies were included in the systematic review, 2 of which were not included in the meta-analysis. The prevalence rate [95%CI] of ICLs was 0.57% [0.48; 0.65] in 1448 patients, 0.22% [0.14; 0.33] in 11583 teeth, with a mean number of lesions equal to 2.24 [1.79; 2.70] in 484 patients evaluated. The incidence rate of new carious lesions developed during orthodontic treatment was 0.48% [0.33; 0.63] in 533 patients, 0.15% [0.08; 0.26] in 1890 teeth with a mean number of ICLs equal to 2.29 [1.12; 3.46] in 208 patients evaluated., Limitations: Although the high number of included studies and the overall good quality, there was a significant heterogeneity in the collected data., Conclusion: The prevalence and incidence rates of ICLs in subjects undergoing orthodontic treatment are quite high and raise some concerns in terms of risk assessment of orthodontic treatment. ICLs represent an alarming challenge for both patients and professionals. Effective caries prevention strategies during treatment need to be considered and implemented where appropriate., (© The Author(s) 2024.

Objectives: The loss of hard dental tissue due to recurrent acid challenges and mechanical stresses without bacterial involvement is known as erosive tooth wear (ETW). Many studies in the literature have concentrated on variables that may affect the ETW process and prevent its occurrence or reduce its advancement. However, to date, no previous systematic review has evaluated the role of calcium in preventing ETW. Therefore, the purpose of the present systematic review was to review and critically appraise the scientific evidence regarding the role of calcium formulations in the prevention of ETW., Methods: The review protocol was registered in the PROSPERO international prospective register of systematic reviews (Ref: CRD42021229819). A literature search was conducted in electronic databases to identify in situ randomized controlled trials evaluating the prevention of ETW following the application of calcium formulations. The outcomes studied included mean enamel loss, surface microhardness, surface roughness, mean erosion/softening depth, mineral loss/precipitation and remineralization. Study characteristics and outcomes of included studies were summarized. Cochrane's risk-of-bias tool 2.0 was used to assess the quality of eligible studies, and meta-analysis using a random effects model was performed., Results: The search retrieved 869 studies of which 21 were considered eligible. Regarding the results of the quality assessment for potential risk of bias in all included studies, overall, 5 studies were considered as being at low risk, another 12 at unclear risk and 4 at high risk of bias. The findings of the studies showed that the addition of calcium in juice drinks led to reduced enamel loss, with blackcurrant juice presenting 2.6 times statistically significant less enamel loss compared to orange juice (p = 0.0001, I 2  = 89%). No statistically significant difference in mean surface microhardness of eroded enamel was recorded between chewing gum with or without casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) (p = 0.31, I 2  = 71%). Contradictory were the results regarding the effect of milk and CPP-ACP pastes on prevention of ETW., Conclusions: Calcium formulations play an important role in ETW prevention, mainly through their addition to acidic drinks., (© 2024.

Objectives: The aim of this randomised, controlled, split-mouth trial was to assess the masking results in initial caries lesions (ICL) that were either resin infiltrated or fluoridated during treatment with fixed orthodontic appliances., Methods: Adolescent patients (age range:12-18years) with fixed orthodontic appliances who had developed ICL [ICDAS 1 or 2 (International Caries Detection and Assessment System)] during orthodontic treatment were consecutively recruited and randomly assigned to either resin infiltration with up to 3 etching procedures (Group:Inf) or to 3-monthly application of a fluoride varnish (Group:FV). Both interventions were performed according to the manufacturer's recommendations. Primary and secondary outcomes (ΔE, ICDAS, DIAGNOdent) included the evaluation of the appearance of the ICL before (T 0 ), 1 week after (T 1 ) treatment and at the last appointment before debonding (T 2 )., Results: Fifteen patients (8females, 7males) with 57ICL were included. Mean (SD) observation time at the last appointment before debonding was 0.5 (0.3) years. At T 0 FV and Inf did not differ significantly in ΔE (median ΔE 0,FV (25th/75th percentiles):11.6 (8.7/20.3): ΔE 0,Inf :15.1 (11.4/19.5); p T0  = 0.135), ICDAS (p T0  = 0.920) and DD (p T0  = 0.367). At T 1 and T 2 ΔE values (p T1 <0.001, p T2 <0.001), ICDAS scores (p T1 <0.001, p T2 <0.001) and DIAGNOdent values (p T1  = <0.001, p T2  = <0.001) for Inf were significantly reduced whereas ΔE values (p T1  = 0.382, p T2  = 0.072) and ICDAS scores (p T1  = 0.268, p T2 <0.001) for FV remained unchanged., Conclusions: Resin infiltration effectively masked ICL during treatment with fixed orthodontic appliances both immediately after application and at the last appointment before debonding. Furthermore, the visual appearance of fluoridated lesions was not as satisfactory as that of the infiltrated ones at both T 1 and T 2 ., Clinical Significance: Resin infiltration effectively masked ICL during treatment with fixed orthodontic appliances both immediately after application and at the last appointment before debonding. Furthermore, the visual appearance of fluoridated lesions was not as satisfactory as that of the infiltrated ones immediately after first application as well as half a year after application., Trial Registration: German Clinical Trials Register (DRKS-ID: DRKS00011797)., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: H.M.-L is appointed as inventor for patents of an infiltration technique for dental caries lesions, held by Charité-Universitätsmedizin Berlin, and receives royalties from DMG, the manufacturer of Icon.

Introduction: The aim was to elucidate the magnitude of alterations in systemic blood counts in healthy patients during the first 14 days after fixed orthodontic appliance placement., Methods: This prospective cohort study consecutively included 35 White Caucasian patients starting orthodontic treatment with fixed appliances. The mean age was 24.48 ± 6.68 years. All patients were physically and periodontally healthy. Blood samples were collected at 3 time points: (1) baseline (exactly before the placement of appliances), (2) 5 days after bonding, and (3) 14 days after baseline. Whole blood and erythrocyte sedimentation rates were analyzed in automated hematology and erythrocyte sedimentation rate analyzer. Serum high-sensitivity C-reactive protein levels were measured by the nephelometric method. Standardized sample handling and patient preparation procedures were adopted to reduce preanalytical variability., Results: A total of 105 samples were analyzed. All clinical and orthodontic procedures were performed without complications or side effects during the study period. All laboratory procedures were performed per protocol. Significantly lower white blood cell counts were detected 5 days after bracket bonding, compared with baseline (P <0.05). Hemoglobin levels were lower at 14 days than baseline (P <0.05). No other significant shifts or alteration patterns were observed over time., Conclusions: Orthodontic fixed appliances led to a limited and transient change in white blood cell counts and hemoglobin levels during the first days after bracket placement. The fluctuation of high-sensitivity C-reactive protein levels was not significant, demonstrating a lack of association between systemic inflammation and orthodontic treatment., (Copyright © 2023 American Association of Orthodontists.

Objectives: The aim was to retrieve the threshold of gingival thickness (GT), where the attribute of gingival translucency through probe visibility was altered., Methods: In 200 patients, the soft tissue thickness was evaluated at both central mandibular incisors using ultrasound quantification (USD). Additionally, probe visibility was determined using a standard periodontal probe (PB) (CPU 15 UNC, Hu-Friedy), inserted 1 mm deep into the gingival sulcus. Frequencies and relative frequencies were calculated. Repeatability analyses and receiver operating characteristics (ROC) were conducted to determine the USD cut-off point for probe visibility., Results: Regression model indicated that the probe was not visible at a thickness of 0.82 mm for the mandibular left central incisor (95% CIs 0.77, 0.86) and became visible at a thickness of 0.69 mm (95% CIs 0.65, 0.72). The respective values for the mandibular right central incisor were 0.82 mm (95% CIs 0.77, 0.87) and 0.70 mm (0.68, 0.74). ROC analysis confirmed the retrieved regression results by indicating the best fitting balance for specificity and sensitivity at a thickness of 0.8 mm for both mandibular incisors., Conclusions: In the frame of the current study, the data revealed that gingiva becomes non-transparent at a thickness of approximately 0.8 mm., Clinical Relevance: Probe visibility at mandibular incisors for the discrimination between thin and thick soft tissues was correlated with a gingival thickness of 0.8 mm and a high repeatability., (© 2022.

Objectives: Objective of this trial was to assess the masking results in initial caries lesions (ICL) that were resin infiltrated during fixed orthodontic treatment in comparison to contralateral teeth that were fluoridated only., Trial Design: A randomized, controlled, split-mouth trial., Methods: Adolescent patients (age range: 12-18 years) with fixed orthodontic appliances who had developed ICL [ICDAS 1 or 2 (International Caries Detection and Assessment System)] during orthodontic treatment were consecutively recruited and randomly assigned to either resin infiltration (Icon) with up to 3 etching procedures (Inf) or to a fluoride varnish (Tiefenfluorid) (FV). Both interventions were performed according to the manufacturer's recommendations. Outcome assessors were blinded to the applied intervention. Primary and secondary outcomes included the evaluation of the appearance of the ICL before (T0) and 1 week after (T1) treatment by digital photographs (ΔE), laser fluorescence readings (DD), and ICDAS scores., Blinding: Due to the treatment nature neither the operators nor the patients could be blinded. However, outcome assessors and the statistician were blinded., Results: Fifteen patients (9 female) with 60 ICL were included (mean age: 14.6 years). At baseline FV and Inf did not differ significantly in ΔE (median ΔE0,T (25th/75th percentiles):10.7(9.1/20.9): ΔE0,I:13.4(10.3/18.5); P = 0.469), DD (P = 0.867) and ICDAS (P = 0.521). One-week after treatment (T1) ΔE values (P < 0.001), DD values (P < 0.001), and ICDAS scores (P = 0.014) for Inf were significantly reduced, whereas ΔE values (P = 0.125) and ICDAS scores (P = 0.073) for FV remained unchanged., Limitation: Natural remineralizing in the standard interventional control group cannot be observed yet, since up to 6 months are needed to naturally remineralize ICL., Conclusions: Based on our short-term data, resin infiltration effectively masked ICL during treatment with fixed orthodontic appliances. Fluoridation was not able to immediately improve the visual appearance of ICL. Further longer-term assessment should focus not only on the aesthetic outcome, but also on the caries inhibitory effect of resin infiltration during treatment with fixed orthodontic appliances., Trial Registration: German Clinical Trials Register (DRKS-ID: DRKS00011797)., (© The Author(s) 2022.

Objective: To systematically retrieve and assess studies regarding the effectiveness of basic behavioral management techniques (BMTs) in pediatric patients., Data Sources: Electronic and hand searches were conducted to locate Randomized Controlled Trials (RCTs) reporting on objective and subjective evaluation of anxiety and behavior of children up to 12 years of age. Data extraction and risk of bias evaluation, using the Cochrane risk of bias tool (RoB 2.0 Tool), were performed independently and in duplicate for all included studies. Mean differences and standard deviations were used to summarize the data from each study and meta-analyses were conducted with studies of limited heterogeneity., Study Selection: A total of 708 papers were identified and screened, 122 retrieved for full text appraisal and 62 finally included. Results suggested that all basic BMTs have acceptable effectiveness on pediatric patients' anxiety, fear and behavior during dental treatment. Meta-analysis showed a statistically significant difference in favor of distraction for subjective anxiety using Facial scale (Mean diff.: 2.78; 95% CI: -3.08, -0.53; p = 0.005) and Modified Child Dental Anxiety Scale (Mean diff.: 12.76; 95% CI: -6.09, -4.47; p = 0.001) and a non-significant difference for heart rate (Mean diff.: 1.70; 95% CI: -6.54, 0.46; p = 0.09). Music significantly reduced heart rate when compared to a control comparator, underlining the superiority of the BMT (Mean diff.: 2.71; 95% CI: -3.70, -0.59; p = 0.007)., Conclusions: Limited evidence about efficacy of one technique over another raises important issues on the topic for future research regarding the management of the child patient in the dental setting of the 21st century., Clinical Significance: Behavioral management comprises a challenge for clinicians, who need to be familiar with a range of techniques to meet patients' needs at individual level and be flexible in their implementation. Appropriate technique should incorporate patients' personality and parents' active involvement, within the contents of the changes in modern societies., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022.

Purpose: To systematically evaluate the available evidence regarding contemporary management of deep caries in vital primary teeth. This review was carried out to facilitate the development of European Academy of Paediatric Dentistry (EAPD) guidelines on deep caries management of primary teeth in paediatric dentistry., Methods: A systematic electronic literature search was conducted to locate studies reporting on interventions and medicaments used for the treatment of deep caries in vital primary teeth. To facilitate this, the Cochrane Library (1992 to up to December 6th, 2020), MEDLINE (PubMed, 1946 to December Week 1, 2020), Ovid MEDLINE (In-Process & Other Non-Indexed Citations, December 6th, 2020); EMBASE (Embase.com, 1974 to December 6th, 2020) and LILACS (1982 to December 6th, 2020) were accessed. Hand search of reference lists of included articles, as well as handbooks and grey literature search was also performed. Study screening was done in duplicate and study inclusions were agreed upon by all authors. Data extraction, and methodological quality and risk of bias assessment were carried out in duplicate for each of the included studies. Overall success rate of each intervention and medicament within the intervention was reported. Meta-analysis was also performed for high-quality studies reporting similar interventions and comparable outcomes in homogeneous population., Results: A total of 1332 papers were identified. Following the primary and secondary assessment process, 36 papers were included in the review. Of these, 8 papers were deemed to represent 4 individual studies, leaving a total of 32 unique studies eventually included in the final analysis. These studies were further categorized into three main vital pulp treatment methods for analysis: indirect pulp capping (IPC), direct pulp capping (DPC), and pulpotomy (PP). Overall, IPC, DPC and PP interventions have high success rates with the reported clinical success rates higher than radiographic success rates. Medicaments used for IPC and DPC have similar success rates. Mineral trioxide aggregate (MTA), ferric sulfate (FS) and formocresol (FC) PP showed similar success rates, and which were all higher than calcium hydroxide (CH). Majority of included studies (n = 22; 63%) were rated low in terms of their potential risk of bias, 6 studies were rated high (17%), and 7 studies were of unclear risk (20%)., Conclusion: Within the limitations of the studies included, IPC, DPC, and PP can be recommended as effective treatment modalities for primary teeth with deep caries under specific conditions., (© 2021.

The curve of Spee (CoS) is an important parameter for an individualized treatment plan. The available information regarding a potential association of the depth of the curve of Spee with various skeletal craniofacial characteristics is conflicting and it is also unknown whether certain craniofacial parameters affect the duration of the levelling phase of orthodontic treatment. A prospective sample of 32 patients with mild to moderate crowding that underwent orthodontic treatment with full fixed appliances was used to study these topics. The craniofacial characteristics were captured on pre-treatment lateral cephalometric radiographs and measurements of the CoS were performed on the initial 3D digital dental models using the Viewbox 4 software. Non-parametric statistics and Spearman's correlations were applied. Weak negative correlations were detected between the CoS depth and the SNA and SNB angles. There was no other association between the CoS and craniofacial parameters, including various anteroposterior measurements. Furthermore, there was no significant association of any craniofacial parameter with the duration of the levelling. Contrary to certain clinical beliefs, it can be argued that the craniofacial characteristics are not associated with the CoS and the time required for its levelling in subjects with moderate pre-treatment CoS depth.

Objectives: Preservation of pulpal vitality in immature permanent teeth with deep carious lesions is essential to enable further root development and apical closure. This systematic review aimed to evaluate the evidence regarding the efficacy, presented clinical and radiographic success, and bacteriological outcomes of techniques and materials used for deep caries management in vital immature permanent teeth., Data: Randomised controlled trials evaluating Vital Pulp Therapy (VPT) for deep caries in immature permanent posterior teeth without history of irreversible pulpitis, and a follow up period of ≥12 months were included. Study characteristics and outcomes of all included studies were summarized. Cochrane's Risk-of-bias tool 2.0 was used to assess the quality of eligible studies. Meta-analyses using a random effects model was performed., Sources: Electronic databases PubMed, Medline, Embase, LILACS, CENTRAL and Cochrane Library were searched, followed by a manual search., Study Selection: Twelve papers were included into the review. Overall success rates were 98%, 93.5%, 93.6% for direct pulp cap (DPC), indirect pulp cap (IPC) and pulpotomy (PP) respectively. Regardless of VPT technique, there were no significant differences between clinical and radiographic success rates. Completion of root development was achieved in more than 83% of the cases in all VPT techniques., Conclusions: All treatment modalities for PP were equally efficient with high overall success rates. Biodentine showed high success rates regardless of technique. No significant differences were found in the clinical and radiographic success rates between various follow-up intervals. There are no clear conclusions regarding superiority of either VPT technique on apical closure., Clinical Significance: This manuscript systematically evaluates the evidence and summarises all available data on each vital pulp therapy technique and materials used in treatment of deep caries in immature permanent teeth with vital pulps. The limitations in the current scientific literature and recommendations for future research are also highlighted., (Copyright © 2022. Published by Elsevier Ltd.)

Aim: Bone remodelling can be followed through the bone turnover markers (BTMs). Aim of the present study was to record the fluctuation of an osteoclastic and an osteoblastic BTM [C-terminal telopeptide of type I collagen (CTX) and N-terminal pro-peptide of type I pro-collagen (PINP), respectively] in both the gingival crevicular fluid (GCF) and the serum of orthodontic patients before and after the initial application of orthodontic forces., Materials and Methods: Twenty-one Caucasian patients were prospectively evaluated. GCF and blood samples were collected in order to measure the selected biomarkers by ELISA at three time-points: exactly before, 5 days, and 14 days after bonding of the appliances. Standardized sample handling and patient preparation procedures were adopted in order to reduce pre-analytical variability., Results: GCF and serum CTX levels were found to be independent of age, although higher in the serum of female subjects. PINP levels were found higher in the serum of patients ≥25 years old, as well as in the GCF of males. A positive correlation between serum and GCF baseline PINP levels was observed., Limitations: The effect of orthodontic treatment on bone remodelling might not be absolutely representative of the local bone microenvironment as the levels of the specific BTMs where measured within the GCF of the lower front teeth., Conclusions: This is the first time PINP and CTX have been evaluated in the GCF and serum of orthodontic patients with fixed appliances. No statistically significant alterations of CTX and PINP levels in the GCF and the serum of patients were recorded over time during the initial stages of orthodontic treatment., (© The Author(s) 2021.

Purpose: To summarise the available data on the effects of chlorhexidine (CHX) mouthwash in treating gingivitis during treatment with fixed orthodontic appliances., Materials and Methods: Multiple electronic databases were searched up to December 7th, 2021. Only randomised controlled trials (RCTs) were eligible for inclusion. The quality of the included RCTs was assessed with the Cochrane risk of bias tool for randomised trials (RoB 2.0). After data extraction and risk of bias assessment, differences were recorded in several oral hygiene indices in time and mean percentage change in those indices using different antimicrobial solutions., Results: Fourteen studies were deemed eligible for inclusion, reporting on a total of 602 patients with an age range of 11-35 years. The experimental solution was a 0.06%, 0.12%, or 0.2% CHX mouthwash with the control either a placebo mouthwash or a selection from a variety of mouthwashes. Treatment duration varied from 1 day to almost 5 months and the follow-up period varied from 1 min to 5 months. Chlorhexidine mouthrinses led to reduced plaque accumulation and gingival inflammation during orthodontic treatment, while at the same time, some of the control group mouthrinses were deemed equally effective. No statistically significant difference was detected in the meta-analysis between CHX and mouthwashes with propolis/probiotics/herbs in terms of the gingival index at 3 to 4 weeks (mean difference 0.07, 95% CI: -0.18, 0.31, p = 0.59)., Conclusion: Chlorhexidine mouthwash in orthodontic patients successfully controls gingival inflammation and bleeding when compared to untreated controls, but is equally effective as other mouthrinses where various oral health indices are concerned.

Since untreated dental caries remain a worldwide burden, this umbrella review aimed to assess the quality of evidence on the clinical effectiveness of different restorative materials for the treatment of carious primary teeth. A literature search in electronic bibliographic databases was performed to find systematic reviews with at least two-arm comparisons between restorative materials and a follow-up period ≥12 months. Reviews retrieved were screened; those eligible were selected, and the degree of overlap was calculated using the 'corrected covered area' (CCA). Data were extracted and the risk of bias was assessed using the ROBIS tool. Fourteen systematic reviews with a moderate overlap (6% CCA) were included. All materials studied performed similarly and were equally efficient for the restoration of carious primary teeth. Amalgam and resin composite had the lowest mean failure rate at 24 months while high-viscosity and metal-reinforced glass ionomer cements had the highest. At 36 months, high-viscosity glass ionomer cements showed the highest failure rate with compomer showing the lowest. Most reviews had an unclear risk of bias. Within the limitations of the review, all materials have acceptable mean failure rates and could be recommended for the restoration of carious primary teeth.
