FREQUENCY OF UNERUPTED MANDIBULAR THIRD MOLAR IN MANDIBULAR ANGLE FRACTURES
AbstractBackground: Fractures of the mandibular angle are common and comprise 31% of all mandibularfractures. Multiple recent studies report a 2–3 fold increased risk for mandibular angle fractureswhen un-erupted mandibular third molars are present. The objective of this study was to assess thefrequency of un-erupted mandibular third molar in mandibular angle fractures. Methods: This crosssectional study was conducted at the Department of Oral and Maxillofacial Surgery, Ayub MedicalCollege, Abbottabad from April to October 2009. One hundred and two patients were included bothfrom the outdoor and ward on consecutive non-probability sampling base. Data were recorded on astructured Performa and analysed using SPSS-16. Results: A hemi-mandible containing un-eruptedmandibular third molar was seen to have a 1.41 times the risk of mandibular angle fracture then ahemi-mandible containing an erupted mandibular third molar. Conclusion: The presence of unerupted mandibular third molar is associated with an increased risk for mandibular angle fracture.Keywords: Maxillofacial trauma, mandibular third molar, mandibular angle fracture
