Abstract

Abstract: Aim: The purpose for this study was to investigate and elucidate the relationships between the mandibular third molar and mandibular angle fractures. Materials and methods: This retrospective study incorporated the presence, position and angulation of mandibular third molar and prevalence of fracture of angle of mandible among patients treated in Hospital Universiti Sains Malaysia. The medical records were scanned and 427 patients with mandibular fractures from 2001 until 2016 were identified. Depending on the notes and various radiographic images, 77 of 427 patients had mandibular angle fracture. The presence or absence of impacted mandibular third molar was assessed for each patient that had angle fracture. In presence of impacted mandibular third molar, their position and angulation of the tooth were evaluated. The positions were classified using Pell and Gregory system while the angulations were classified using Winter's classification. Data were analysed using SPSS 22.0 system and applying a chi‐square test. Results: Among 77 patients with angle fracture, 67 (87%) had impacted mandibular third molar while 10 (13%) had no evidence of mandibular third molar. The incidence of mandibular angle fracture was found to be significantly greater when impacted third molar was present ( P < 0.05). Conclusion: The results of this study showed that the patients with impacted mandibular third molar have an increased risk of mandibular angle fracture compared to those without.
