Success rate of Hall Technique for restoring carious primary molars - systematic review and meta-analysis.

OBJECTIVES: The overall pooled success rate of the Hall Technique (HT) in various types of studies has not been investigated. The present study aims to evaluate the success rate of HT to restore carious primary molars. METHODS: A systematic search was carried out in the MEDLINE/PubMed, Excerpta Medica Database (EMBASE), Scopus, Web of Science, and LIVIVO electronic databases, as well as the ProQuest database for grey literature review. A search was carried out up to September 2023 for studies meeting the eligibility criteria: Randomised Clinical Trials (RCTs) and Non-Randomised Studies of Interventions (NRSIs); children with primary molars treated using HT; and reporting success for at least 1-month post-treatment. Single-arm meta-analysis assessed the pooled proportion (95% CI) of HT success rates. Risk of bias and certainty of evidence using the GRADE approach were assessed. RESULTS: Searching identified 665 studies, with 25 (15 RCTs and 10 NRSIs) meeting the eligibility criteria. In meta-analyses of RCTs, the pooled proportion success rate was 98% (95% CI: 97-99%) at 12-month follow-up. For NRSIs, the pooled proportion success rate was 95% (95% CI: 91-100%) up to 89 months. CONCLUSIONS: HT presents a high success rate, even though the primary studies had "low" to "high" risk of bias and demonstrated "moderate" to "low" certainty of evidence. One of the main reasons for downgrading was related to blinding, which was generally unfeasible due to visibly different restorative materials. The systematic review protocol was registered in PROSPERO (ID: CRD42021204415).

Strategies for Pain Management after Extraction of Primary Teeth: A Systematic Review of Randomized Clinical Trials.

BACKGROUND: In dental extractions, particularly when local anesthesia is used, it usually offers analgesic relief for a few hours. However, pain can become a notable concern in the immediate postoperative period due to the trauma experienced by both soft and hard oral tissues. OBJECTIVES: This systematic review aimed to evaluate the most effective strategies for managing postoperative pain in primary tooth extractions. METHODS: Two examiners conducted a search across five electronic databases: MEDLINE (via PubMed), Embase, Scopus, Web of Science, CENTRAL, and OpenGray. Studies were included if they met the following criteria after reviewing their titles and abstracts: they involved children and evaluated pain management following primary tooth extraction. Subsequently, articles that described extractions performed under any form of sedation, were not conducted under local anesthesia, in an outpatient setting, and in children aged 0 to 12 years, or were not randomized controlled trials, were excluded. RESULTS: The search yielded 374 relevant articles, of which 9 were included. Among these, 5 utilized preoperative medications as a pain management strategy, one evaluated low-level laser therapy (LLLT) postoperatively, one assessed calendula drops postoperatively, and another explored virtual reality during the procedure and arnica in solution both pre and postoperatively. CONCLUSION: Among all the strategies evaluated, the strategy involving analgesics administered 30 minutes before tooth extractions was supported by better-designed studies. However, there is a high risk of bias.

Selective Caries Removal: A Case Report with 21-Year Follow-Up.

Dental caries remains the most prevalent chronic disease globally, and its management should adhere to the principles of minimal intervention dentistry. This study reports a series of successful cases involving the selective removal of carious tissue in permanent molars, with follow-up periods of up to 21 years. Six permanent molars with severe and deep carious lesions were treated with selective caries removal and restored with high-viscosity glass ionomer cement. Clinical examination revealed that the teeth were free from pain and sensitivity. Follow-up assessments were conducted at 7 and 21 years posttreatment. Treatment success was defined by the absence of clinical and radiographic signs, symptoms of pulp alterations, and lesion arrest. Successful minimally invasive approaches were observed with selective removal of carious tissue and maintenance of pulp vitality for up to 21 years.

CONSORT statement adherence and risk of bias in randomized controlled trials on deep caries management: a meta-research.

BACKGROUND: Recently, trials have supported changes in deep caries management. However, reporting might lack details, affecting interpretation and implementation. Thus, we aimed to evaluate the adherence to the CONSORT statement and the risk of bias of randomized controlled trials (RCTs) on deep caries management published in pediatric dental journals. METHODS: We searched PubMed for RCTs in six pediatric dental journals between 2010 and 2022, focusing on deep caries lesion management. Adherence to the CONSORT guideline and the risk of bias were assessed using a modified tool with 19 items; each scored from 0 to 2 (maximum of 38 points), and the Cochrane risk-of-bias (RoB 2) tool. We performed descriptive and regression analyses (α = 5%). RESULTS: We analyzed 127 RCTs. The mean (standard deviation) CONSORT adherence score was 21.1 (6.7). Notably, 96.1% of the studies received a score of 2 for the "intervention" item, whereas 83.5% scored 0 for the "estimated effect size". The risk of bias assessment revealed that 40.2% of the RCTs were at high risk, 59% were at low risk, and 0.8% were at low risk. RCTs with a high risk of bias had lower CONSORT scores (p<0.001) than those with low or some concerns. RCTs published in journals without the endorsement of the CONSORT statement had lower scores than those in journals with the endorsement of the CONSORT statement. Older RCTs (6-10 years old and more than 10 years old) showed significantly lower CONSORT statement compliance than trials published recently within 5 years. CONCLUSION: Adherence to the CONSORT was relatively low among the investigated RCTs. Moreover, lower adherence to the CONSORT was associated with a higher risk of bias. TRIAL REGISTRATION: This study protocol was prospectively registered on the Open Science Framework - DOI ( 10.17605/OSF.IO/V6SYZ ).

2-year survival and cost analysis of occlusoproximal ART restorations using encapsulated glass ionomer cement in primary molars: a randomized controlled trial.

BACKGROUND: The survival of ART restorations can be influenced by the choice of the restorative material. The aim of this randomized non-inferiority controlled trial was to compare the 2-year survival rate and cost analysis of two encapsulated glass ionomer cements (GIC) as occlusoproximal restorative materials in primary molars. METHODS: Children from public schools in Tietê (Brazil), aged 4-8 years with occlusoproximal dentine carious lesions in primary molars were selected and randomly assigned to receive either Equia Forte (EF) or Riva Self Cure (RSC) as restorative materials. Treatment was carried out by two trained final-year dental students in schools following ART premises. Restorations were assessed by a trained and calibrated examiner after 2, 6, 12, 18, and 24 months. The primary outcome was restoration survival after 2 years, analyzed using Kaplan-Meier survival and Cox regression analysis (α = 5%). Professional and materials costs for each group were collected in Brazilian Reais (R$) and converted into US dollars (US$) and analyzed using Monte-Carlo simulation. RESULTS: A total of 152 children (76 per group) were included in the study, and 121 (79%) were evaluated after 2 years. The overall 2-year restoration survival rate was 39% (EF = 45%; RSC = 32%) with no difference between the groups. The baseline and 2-year total cost of restorations using RSC was lower when compared to EF (incremental cost: US$ 6.18). CONCLUSION: After two years of follow-up, Riva Self Cure shows comparable restoration survival rates to Equia Forte, being more cost-effective in the Brazilian perspective. TRIAL REGISTRATION: This randomized clinical trial was registered on ClinicalTrials.Gov - NCT02730000.

Where do we invest money to implement active learning on caries detection? An economic evaluation.

This trial-based economic evaluation aimed to estimate the incremental cost of implementing an active learning strategy (theoretical-practical workshop) to substitute the didactic lecture as the sole method for students training in caries detection. We also provided a budget impact analysis and explored the composition of costs related to the activity. Data from the coordinating centre of a multicentre randomized and controlled study (IuSTC01) was analyzed as the first part of our main economic analysis plan. The perspective of the educational provider (the institution implementing the activity) was considered, and an immediate time horizon was adopted. All used resources were valued in Brazilian Real by adopting a microcosting strategy. Costs for each strategy were estimated and converted into international dollars. The incremental Cost per student and the total cost of implementing the complete teaching strategy for 80 students were calculated. Monte Carlo simulations were used to estimate the uncertainties. The incremental Cost estimated for the workshop implementation would be $7.93 per student (interquartile range (IQR): $7.8-8.1), and the total cost of the teaching activity would be $684 (IQR:672-696). The laboratory training comprised more than 50% of the total amount spent, and a higher percentage of this value was related to human resources costs (72%). Saving 40% of the costs could be expected for the next rounds of activities in the institution, assuming no need for additional preparation of didactic materials and tutor training. A modest incremental cost per student and an acceptable organizational budget impact should be expected for the institution when including active learning training in caries detection for undergraduate students, mainly related to the human resources involved.

How different attributes are weighted in professionals' decision-making in Pediatric Dentistry-a protocol for guiding discrete choice experiment focused on shortening the evidence-based practice implementation for dental care.

BACKGROUND: Important evidence has been constantly produced and needs to be converted into practice. Professional consumption of such evidence may be a barrier to its implementation. Then, effective implementation of evidence-based interventions in clinical practice leans on the understanding of how professionals value attributes when choosing between options for dental care, permitting to guide this implementation process by maximizing strengthens and minimizing barriers related to that. METHODS: This is part of a broader project investigating the potential of incorporating scientific evidence into clinical practice and public policy recommendations and guidelines, identifying strengths and barriers in such an implementation process. The present research protocol comprises a Discrete Choice Experiment (DCE) from the Brazilian oral health professionals' perspective, aiming to assess how different factors are associated with professional decision-making in dental care, including the role of scientific evidence. Different choice sets will be developed, either focusing on understanding the role of scientific evidence in the professional decision-making process or on understanding specific attributes associated with different interventions recently tested in randomized clinical trials and available as newly produced scientific evidence to be used in clinical practice. DISCUSSION: Translating research into practice usually requires time and effort. Shortening this process may be useful for faster incorporation into clinical practice and beneficial to the population. Understanding the context and professionals' decision-making preferences is crucial to designing more effective implementation and/or educational initiatives. Ultimately, we expect to design an efficient implementation strategy that overcomes threats and potential opportunities identified during the DCEs, creating a customized structure for dental professionals.

Risk of Bias and Methodological Critical Appraisal in Systematic Reviews of Non- and Micro-Invasive Caries Management for Primary and Permanent Teeth.

INTRODUCTION: Pediatric dentistry should rely on evidence-based clinical decisions supported by high-quality, unbiased systematic reviews (SRs). Therefore, the purpose of this study was to systematically evaluate the methodological quality and risk of bias of SRs focused on non- and micro-invasive treatment for caries lesions in primary and permanent teeth. METHODS: A comprehensive search was conducted in multiple databases, including MEDLINE/PubMed, Scopus, Web of Science, EMBASE, Epistemonikos, and ProQuest, up to March 2023 to identify relevant systematic reviews (SRs) focused on non- and micro-invasive caries treatment. Two independent reviewers extracted data from the included SRs and assessed the methodological quality and risk of bias using the AMSTAR 2 and ROBIS tools, respectively. RESULTS: A total of 39 SRs were included in the analysis. Among these, 27 SRs (69.2%) were assessed as having critically low methodological quality, 11 SRs (28.2%) were considered to have low methodological quality, and only one SR was rated as high-quality. The primary concern identified was the absence of protocol registration before commencing of the study, observed in 33 SR when using the AMSTAR 2 tool. According to the ROBIS tool, 21 studies (53.8%) were categorized as low risk of bias, 10 (25.6%) as high risk, and eight (20.5%) as unclear risk of bias. CONCLUSION: Our analysis revealed that SRs focused on non- and micro-invasive treatment for caries in children and adolescents had critically low methodological quality according to the AMSTAR 2 tool but demonstrated a low risk of bias based on the ROBIS tool. These findings highlight the importance of emphasizing prospective protocol registration, transparent reporting of statistical analyses, and addressing potential bias implications within this topic. By addressing these issues, we can enhance the quality of SRs and ensure that clinical decisions rely on unbiased and trustworthy evidence.

Periodontal status among 12-year-old schoolchildren: a population-based cross-sectional study in Quito, Ecuador.

This study aimed to estimate the prevalence and extent of bleeding on probing and calculus in 12-year-old schoolchildren of Quito, Ecuador, and evaluate the associated factors. We conducted an epidemiological survey with a representative sample of 1,100 12-year-old schoolchildren from public schools in the urban area of Quito, Ecuador. We assessed the periodontal health using the Community Periodontal Index (CPI). The prevalence and extent of the periodontal condition was based on the presence of at least one site with bleeding on probing (BOP), and the presence of dental calculus was also evaluated. We used univariate and multiple multilevel Poisson regression analyses to verify the association between the independent variables and the number of sextants with BOP and calculus. The prevalence of BOP and calculus was 92% and 69.9%, respectively. The adjusted mean of the affected sextants was 4.3 and 2.2 for BOP and calculus, respectively. The mother's schooling and malocclusion were associated with the number of sextants with bleeding. The mother's schooling and dental caries experience were associated with calculus. Gingival bleeding and the presence of dental calculus are highly prevalent in 12-year-old schoolchildren from Quito. Gingival bleeding is associated with maternal education and malocclusion, and dental calculus is associated with maternal education and dental caries.

Association of children's oral health and school environment on academic performance in 12-year-old schoolchildren of Quito, Ecuador.

OBJECTIVES: The primary aim of this study was to evaluate if children's oral health and oral health-related quality of life (OHRQoL) were associated with school performance. Moreover, the study aimed to examine whether school environment factors influenced this association. METHODS: This cross-sectional study was based on a population-based sample of 998 12-year-old schoolchildren from 31 public schools in Quito, Ecuador. Trained and calibrated examiners conducted clinical exams for dental caries, dental trauma and malocclusion. Furthermore, children completed the Spanish version of the Child Perception Questionnaire (CPQ11-14 ), and their parents answered questions about socio-economic status. School coordinators provided information on the physical environment, promotion of health practices and the occurrence of negative episodes in the school. There were three outcomes: grades obtained in Spanish language and mathematics and the number of missed school days. Multilevel linear and Poisson regression models were conducted using a hierarchical approach to include the variables guided by a previously created direct acyclic graph. RESULTS: Children with dental trauma and higher CPQ11-14 scores showed lower grades and school attendance. Schoolchildren from schools with episodes of vandalism had more school days missed. CONCLUSION: The school performance of 12-year-old children is affected by dental trauma and by a worse OHRQoL, as well as a negative school environment. Therefore, supportive environments and promoting health measures in schools could overcome this worse academic performance in children with oral health problems.

Factors influencing the impact of randomized clinical trials on dental implants: A bibliometric analysis.

OBJECTIVE: To analyze bibliometrics, characteristics, and the risk of bias of randomized controlled trials (RCTs) on dental implants published in six high-impact factor journals and to identify factors contributing to citation number. MATERIALS AND METHODS: A systematic electronic search was conducted in four databases (PubMed, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials) to identify RCTs on dental implants published in six dental journals between 2016 and 2017. Twenty-five bibliometric variables and paper characteristics were extracted to evaluate their contribution to the citation count. Risk of bias analysis was performed using the RoB2 tool. Negative binomial regression was used to examine the effects of predictor variables on the Citation count. Significance level was set to 5%. RESULTS: A total of 150 RCTs included received a cumulative citation count of 3452 until July 2022. In the negative binomial regression analysis, open-access RCTs exhibited 60% more citations, and RCTs that presented statistical significance received 46% more citations. Conversely, first author affiliations from Africa, Asia and Oceania continents showed 49% fewer citations than publications from Europe. Regarding the risk of bias, 73.3% of the RCTs had some concerns, while 26% were deemed to have a high risk of bias. Only one RCT (0.07%) showed a low risk of bias. CONCLUSION: Within the limitation of the study, factors such as open access, statistically significant results, and country influence the number of citations received by the RCTs on dental implants.

Which Dental Procedures Lead to Greater Distress During Children's Dental Treatment? A Cohort Study

ABSTRACT Objective: To assess children's self-reported distress during dental procedures and investigate risk factors. Material and Methods: A total of 163 children (3-10 years old) were included from a clinical trial on diagnostic strategies for evaluating restorations in primary teeth. Treatment plans were elaborated based on the clinical examination performed at the baseline of the study. Dentists performed 742 dental procedures, and an external evaluator collected children's self-reported distress through the Wong Backer Facial Scale (WBFS) and dentists' opinions about children's behavior during the treatment. Kruskal-Wallis Test was performed to compare the distress and the dentists' perception of the different dental procedures, and multilevel ordered logistic regression analysis was conducted to the evaluate association between explanatory variables and the outcomes. Results: More complex procedures caused more distress in children (p=0.017), with a 5.5 times higher risk than simple operative treatments. Similarly, dentists reported children's worse behavior (p<0.001). Older children (older than 7 years) reported less distress than younger children (OR 0.52; CI 0.30-0.87; p=0.014). Patients reported greater distress in the first consultations, reducing the chance of higher scores by 16% in the next interventions. Conclusion: Children experience higher levels of distress during their first treatment appointments. More complex operative procedures and the child's age below 7 years were risk factors associated with greater distress during dental treatment.

Restoration-repair potential of resin-modified glass ionomer cement

Abstract: This in vitro study aimed to evaluate the repair bond strength of resin-modified glass ionomer cement using either the same material or a universal adhesive in the etch-and-rinse and self-etch modes plus resin composite. Twenty-four resin-modified glass ionomer cement blocks were stored in distilled water for 14 d and thermocycled. Sandpaper ground specimens were randomly assigned to three experimental groups according to the repair protocol: resin-modified glass ionomer cement (Riva Light Cure, SDI) and universal adhesive (Scotchbond Universal Adhesive, 3M Oral Care) in etch-and-rinse or self-etch modes and nanohybrid resin composite (Z350 XT, 3M Oral Care). After 24 h of water storage, the blocks were sectioned, and bonded sticks were subjected to the microtensile bond strength (μTBS) test. One-way ANOVA and Tukey's test were used to analyze the data. The failure mode was descriptively analyzed. The highest μTBS values were obtained when the resin-modified glass ionomer cement was repaired using the same material (p < 0.01). In addition, the mode of application of the universal adhesive system did not influence the repair bond strength of the resin-modified glass ionomer cement. Adhesive/mixed failures prevailed in all groups. Repair of resin-modified glass ionomers with the same material appears to be the preferred option to improve bond strength.

Do the clinical practice guidelines for paediatric dentistry meet the quality standards? A meta-research and quality appraisal using the AGREE II tool.

BACKGROUND: Clinical practice guidelines (CPGs) enhance health care and aid clinicians' decisions. AIM: To evaluate the quality of clinical guidelines in paediatric dentistry using the AGREE II tool. DESIGN: PubMed, EMBASE, Scopus, LIVIVO, Lilacs, international guidelines websites, scientific societies, and gray literature were searched until September 2021. We included paediatric dental clinical guidelines and excluded drafts or guidelines for patients with special needs. Two independent reviewers performed quality assessment using the APPRAISAL OF GUIDELINES FOR RESEARCH & EVALUATION II (AGREE II) instrument. We calculated the mean overall domain scores (95% confidence interval) for each guideline. We used regression analysis to correlate the score of overall assessment and the six domains of AGREE II with guideline characteristics. RESULTS: Forty-four guidelines were included in this study. Highest mean score was for Domain 4 (Clarity of Presentation; 58%, 95% CI: 50.8-64.9), whereas the lowest was for Domain 5 (Applicability; 16%, 95% CI: 10.8-21.4). The reporting quality was improved in Domains 1-5 with reporting checklists (p < .001), whereas that of Domain 6 was improved by decreasing years since publication (p = .047). CONCLUSION: Paediatric dental guidelines do not comply with the methodological quality standard, especially in Domain 5 (Applicability). The AGREE reporting checklist should be implemented with a system to evaluate the certainty of evidence for future guidelines.

Atraumatic Restorative Treatment (ART) as Public Policy: a Scoping Review / O Tratamento Restaurador Atraumático (ART) como Política Pública: uma Revisão de Escopo

This scoping review aimed to identify, describe, and analyze the use of Atraumatic Restorative Treatment (ART) as public policy. Inclusion criteria: studies on public oral health policies; dental caries; ART. Exclusion criteria: clinical studies; specific interventions; studies that report public policies that do not use ART as a strategy for caries treatment. The search was conducted in PubMed, BVS, Epistemonikos, Health Systems Evidence, and Rxforchange. The selection process and data extraction were performed by two authors independently according to the stages and categories of a conceptual framework. Of the 2253 eligible articles, 139 were duplicates, and 1680 were not included after reading the title and abstract. After assessing the full text, 414 articles were excluded. Twenty articles were included. Nineteen were conducted in nine countries (South Africa, Bolivia, Cambodia, Egypt, Mexico, Tanzania, East Timor, Tunisia, and Zimbabwe), and one in the Americas. The studies reported high prevalence of dental caries and lack of access to restorative procedures in health services as common problems. Policy developments followed a similar process, with the presence of governments, conceptual use of scientific evidence, and induction by the World Health Organization. Regarding implementation barriers, the included studies mentioned the lack of supplies and lack of induction by managers,while in relation to the facilitators, permanent education and professional practice were mentioned. Cohort studies have shown a survival rate greater than 80% after one year of follow up of the restorations performed. The findings of this review indicate that the use of ART in public policies is promising, however, its use is still in an early stage. (AU)

Vinte artigos foram incluídos. Dezenove foram realizados em nove países (África do Sul, Bolívia, Camboja, Egito, México, Tanzânia, Timor Leste, Tunísia e Zimbábue) e um nas Américas. Os estudos relataram alta prevalência de cárie dentária e falta de acesso a procedimentos restauradores nos serviços de saúde como problemas comuns. Os desenvolvimentos de políticas seguiram um processo semelhante, com a presença de governos, uso conceitual de evidências científicas e indução da Organização Mundial da Saúde. Quanto às barreiras de implementação, foram mencionadas a falta de insumos e a falta de indução por parte dos gestores. Quanto aos facilitadores, foram citados a educação permanente e a prática profissional. Estudos de coorte mostraram sobrevida superior a 80% após um ano de acompanhamento. Os achados desta revisão indicam que a utilização da ART nas políticas públicas é promissora, porém, sua utilização ainda é incipiente. (AU)

Methodological quality of network meta-analysis in dentistry: a meta-research.

This meta-research aimed to provide an overview of the methodological quality and risk of bias of network meta-analyses (NMA) in dentistry. Searches for NMA of randomized clinical trials with clinical outcomes in dentistry were performed in databases up to January 2022. Two reviewers independently screened titles/abstracts, selected full texts, and extracted the data. The adherence to PRISMA-NMA reporting guideline, the AMSTAR-2 methodological quality tool, and the ROBIS risk of bias tool were assessed in the studies. Correlation between the PRISMA-NMA adherence and the AMSTAR-2 and ROBIS results was also investigated. Sixty-two NMA studies were included and presented varied methodological quality. According to AMSTAR-2, half of the NMA presented moderate quality (n = 32; 51.6%). The adherence to PRISMA-NMA also varied. Only 36 studies (58.1%) prospectively registered the protocol. Other issues lacking of reporting were data related were data related to the NMA geometry and the assessment of results consistency, and the evaluation of risk of bias across the studies. ROBIS assessment showed a high risk of bias mainly for domains 1 (study eligibility criteria) and 2 (identification and selection of studies). Correlation coefficients between the PRISMA-NMA adherence and the AMSTAR-2 and ROBIS results showed moderate correlation (rho < 0.6). Overall, NMA studies in dentistry were of moderate quality and at high risk of bias in several domains, especially study selection. Future reviews should be better planned and conducted and have higher compliance with reporting and quality assessment tools.

Is there an acceptable surrogate for caries clinical trials? Evidence from a systematic review of primary studies.

BACKGROUND: There is currently a lack of evidence supporting the use of valid surrogates in caries clinical trials. This study aimed at examining the validity of two surrogate outcomes used in randomized clinical trials for caries prevention, pit and fissure sealants and fluoridated dentifrices, according to the Prentice criteria. METHODS: A systematic review was conducted in MEDLINE (PubMed), LILACS and Scopus databases up to 05 October 2022. The grey literature and the list of eligible studies' references were also screened. The search was conducted, selecting randomized clinical trials focussed on dental caries prevention using pit and fissure sealants or fluoridated dentifrices and with at least one surrogate endpoint for cavitated caries lesions. The risk of each surrogate endpoint and for the occurrence of cavitated caries lesions was calculated and compared. The association between each surrogate and the presence of cavitation was quantified, and each outcome was assessed graphically for validity according to the Prentice criteria. RESULTS: For pit and fissure sealants, from 1696 potentially eligible studies, 51 were included; while for fluoridated dentifrices, of 3887 potentially eligible studies, four were included. Possible surrogates assessed were retention of sealants, presence of white spot lesions, presence of plaque or marginal discoloration around the sealants, oral hygiene index, radiographic and fluorescence caries lesion assessments. However, only the retention of sealants and the presence of white spot lesions could be evaluated for their validity according to the Prentice criteria. CONCLUSION: Loss of retention of sealants and the presence of white spot lesions do not fulfil all of the Prentice criteria. Therefore, they cannot be considered valid surrogates for caries prevention.

Associated factors and treatment options for sleep bruxism in children: an umbrella review.

Data on clinical management options for sleep bruxism in the primary dentition are inconclusive. This umbrella review aimed to synthesize the available evidence from systematic reviews (SRs) on the associated factors and treatment approaches for clinical management of sleep bruxism in children. A search was conducted in the MEDLINE/PubMed, Web of Science, Embase, and OpenGrey databases up to March 2022. SRs published on sleep bruxism in children containing data on associated factors or treatment outcomes were included. The AMSTAR-2 tool was used to assess the methodological quality of SRs. The search identified 444 articles, of which six were included. Sleep conditions, respiratory changes, personality traits, and psychosocial factors were the associated factors commonly identified. Treatments included psychological and pharmacological therapies, occlusal devices, physical therapy, and surgical therapy. All SRs included presented a high risk of bias. Overlapping of the included studies was considered very high. The best evidence available to date for the management of sleep bruxism in children is based on associated factors, with sleep duration and conditions, respiratory changes, as well as personality traits and psychosocial factors being the most important factors commonly reported by studies. However, there is currently insufficient evidence to make recommendations for specific treatment options.
