A systematic review and meta-analysis of oral and maxillofacial trauma.

Objective of work: The aim of this study was to determine the most frequent injuries and their relationship with gender, age and aetiology. Materials and Methods: An Epidemiologic Systematic Review was carried out, in the databases PUBMED and Scopus, between 2010-2020. We used Joanna Briggs Institute Checklist to access the Risk of Bias and Grading of recommendations, assessment, development, and the evaluations (GRADE) method was applied to assess the quality of the evidence of the 78 included articles. Results and Conclusions: Out of the 78 articles included, 14 were classified as moderate-risk bias and 58 as low risk. Only 20.5% had a prospective design and the male/female ratio ranged from 0.299 to 11.83. The majority of the studies described fractures (67) and only 26 reported dental injuries. The studies were distributed into five regions of countries: Asia, Africa, Latin America, Europe and Muslin regions. The results showed that road traffic accidents (55.37%) were the most frequent type of trauma, followed by assault (17.56%) and falls (10.21%). Fractures were the most prevalent injuries (84.3%). It was possible to establish an association between road traffic accidents and Asian countries. Assaults were more frequent in Africa, predominantly males, whilst falls increased with age, amongst women, in European countries. Fractures were usually observed in Muslin regions.
