retained third molars, practices of mandibular condyle region, mandibular integrity


Purpose: Assess mandibular condylar/subcondylar and angle fracture patterns in the presence or absence of third molars. Patients and Methods: Retrospective cohort study of 234 patients with mandibular fractures. Odds ratios were calculated to determine relative risk of angle and condylar/subcondylar fractures when third molar teeth were present or absent. Results: Condylar/subcondylar fractures were twice as likely to be avoided if a third molar was present; angle fractures were twice as likely to occur with retained third molars. Conclusions: A twofold decrease occurs in the risk of condylar/subcondylar fracture if a third molar is present and a twofold increase occurs in mandibular angle fractures if a third molar is retained.
