Objectives To synthesise available knowledge about both sleep (SB) and awake bruxism (AB) as depicted by previous published systematic reviews (SR). Methods SR investigating any bruxism‐related outcome were selected in a two‐phase process. Searches were performed on seven main electronic databases and a partial grey literature search on three databases. Risk of bias of included SR was assessed using the “University of Bristol's tool for assessing risk of bias in SR”. Results From 1038 studies, 41 SR were included. Findings from these SR suggested that (a) among adults, prevalence of AB was 22%‐30%, SB (1%‐15%), and SB among children and adolescents (3%‐49%); (b) factors consistently associated with bruxism were use of alcohol, caffeine, tobacco, some psychotropic medications, oesophageal acidification and second‐hand smoke; temporomandibular disorder signs and symptoms presented a plausible association; (c) portable diagnostic devices showed overall higher values of specificity (0.83‐1.00) and sensitivity (0.40‐1.00); (d) bruxism might result in biomechanical complications regarding dental implants; however, evidence was inconclusive regarding other dental restorations and periodontal impact; (e) occlusal appliances were considered effective for bruxism management, although current evidence was considered weak regarding other therapies. Conclusions Current knowledge from SR was mostly related to SB. Higher prevalence rates were found in children and adolescents than in adults. Associated factors and bruxism effects on stomatognathic structures were considerably heterogeneous and inconsistent. Overall good accuracy regarding portable diagnostic devices was found. Interventions' effectiveness was mostly inconclusive regarding the majority of available therapies, with the exception of occlusal appliances.

Backgrounds/Aims Contact sports present intense physical contact, and usually, players have a high risk for dentofacial injuries. It is unclear how often these injuries occur and which contact sports present the highest rates. The aim of this study was to assess the prevalence of dentofacial injuries among contact sports participants. Methods A literature search was performed in seven electronic databases (Embase, LILACS, LIVIVO, PubMed, Scopus, SportDiscus, and Web of Science). The gray literature (Google Scholar, OpenGrey, and ProQuest), as well as the reference lists of included studies, was assessed. Experts were consulted to indicate additional studies. The eligible studies were observational studies that contained details of the contact sports participants who were aged over 18 years old, either professional or not, who sustained at least one dentofacial injury in the past, the number of sustained injuries, and studies which provided quantitative data on the characteristics of the dentofacial injuries, such as type and site. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data. Results Among 1152 identified studies, 17 articles remained for final analysis. One study was classified as high risk of bias, 14 studies as moderate, and two as low risk. The overall prevalence of dentofacial injuries was 27.57% (95% CI: 17.87‐38.47). The prevalence in each sport was rugby 37.36% (95% CI: 17.45‐59.82), basketball 27.26% (95% CI: 9.45‐50.08), handball 24.59% (95% CI: 14.88‐35.83), and field hockey 19.07% (95% CI: 6.82‐35.62). The most common injury was dental injury 19.61% (95% CI: 8.13‐34.56). Conclusion The overall prevalence of dentofacial injuries among collective contact sports participants was approximately 30%. The most common injury presented was dental injury.

Background:The COVID-19 pandemic health crisis has changed household and school routines leaving children and adolescents without important anchors in life. This, in turn, can influence their mental health, changing their behavioral and psychological conditions. Aims:To systematically review the literature to answer the question: "What is the worldwide prevalence of mental health effects in children and adolescents during the COVID-19 pandemic?".Methods: Embase, Epistemonikos database, LILACS, PsycINFO, PubMed, Scopus, Web of Science, and World Health Organization Global literature on coronavirus disease were searched. Grey literature was searched on Google Scholar, Grey Literature Report, and Preprint server MedRxiv. Observational studies assessing the prevalence of mental health effects in children and adolescents during the COVID-19 pandemic were included. Four authors independently collected the information and assessed the risk of bias of the included studies.Results: From a total of 11,925 identified studies, 2873 remained after the removal of the duplicated records. Nineteen studies remained after the final selection process.

Objective The unavoidable extraction of teeth in the esthetic area can be overcome through different treatment modalities. Recently, immediate implants appeared as a minimally invasive approach to resolving these cases; however, immediate implant loading is not always possible or indicated. In these cases, an innovative approach through customized healing abutments could be used to preserve the soft tissue contour, eliminating the need for reopening surgery and the use of provisional restorations to condition the mucosal contour. Clinical Considerations The present cases describe a simplified chairside approach to use customized healing abutments for immediate implants placed after tooth extraction in the anterior and posterior areas in order to maintain the soft tissue contours while reducing the clinical steps until delivering the final restorations. Conclusions This technique seems to be effective to guide the soft tissue healing around dental implants allowing a natural emergence profile with implant‐supported restorations, reducing the number of treatment steps. Clinical Significance The use of customized healing abutments prepares soft tissue for the prosthetic stage preserving its contours and eliminating the need for reopening surgery.
