Relação entre terceiros molares inferiores e risco de fratura do ângulo mandibular: revisão integrativa da literatura

Abstract

Objective: To verify, through an integrative literature review, the relationship between lower third molars and the risk of mandibular angle fracture. Material and Methods: Data were obtained through searches in the Public Medicine Library (PubMed), Scopus and Web of Science databases, during April 2023. Inclusion criteria were retrospective observational studies, performed with humans with angle fractures, whose etiology was trauma, published between 2013 and 2023, in English. Exclusion criteria were review studies, case reports, books, letters and editorials, studies in animal models and 3D models, and angle fractures caused by iatrogenic injury. Data extraction and analysis was performed using Microsoft Excel®. Results: Twelve studies were analyzed, comprising 3,272 patients, of which 81.05% were men, with a mean age of 30.27 years and 1,436 angle fractures, the main etiology of which was a traffic accident. Lower third molars classified as Class II and Position B according to Pell and Gregory were the most associated with angle fractures. Final considerations: Lower third molars increase the risk of fracture of the mandibular angle, especially if they are partially impacted in males.
