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/Aims As the popularity of sports activities grows, so do the number of sport‐related injuries. Furthermore, sports that use equipment or vehicles that modify the speed of the player can present more serious injuries. The aim of this systematic review was to identify the overall prevalence of orofacial trauma in wheeled non‐motor sports athletes. Methods The search strategy was applied in eight electronic databases (Embase, LILACS, Livivo, PEDro, PubMed, Scopus, SportDiscus, and Web of Science). Additionally, a complementary search of the gray literature (Google Scholar, OpenGrey, and ProQuest Dissertations & Theses Global), reference lists of included articles, and studies indicated by experts on the subject was done. The included articles were observational studies with sufficient data of orofacial trauma (type and anatomical site) in wheeled non‐motor sport athletes, regardless of the competition level. Risk of bias was assessed by using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data. The meta‐analysis was performed using R Statistics software, and the strength of cumulative evidence was assessed by The Grading of Recommendations Assessment, Development, and Evaluation. Results From 4042 identified studies, after the removal of duplicates and phase one of selection (title and abstracts screening), 251 studies remained for phase two (full‐text screening). Five articles were finally included. One study was considered to have a low risk of bias and four had a moderate risk of bias. The cumulative prevalence of orofacial injuries in wheeled non‐motor sport athletes was 21.7% (CI: 8.7–34.7; I2:97.6%) and the prevalence of dental injuries in these sports was 7.5% (CI:4.3–10.7; I2:61.9%). The certainty in cumulative evidence was considered to be very low. Conclusion About 22% of the wheeled non‐motor sport athletes have suffered orofacial injuries. The most prevalent type of injury was classified as dental trauma.
