Section snippets
Patients and Methods
Information was obtained retrospectively from clinical notes, surgical records, and radiographs. From April 1999 until July 2004, 114 patients were treated for 115 fractures of the mandibular angle by the Division of Oral and Maxillofacial Surgery at Piracicaba Dental School, State University of Campinas-Unicamp, São Paulo, Brazil. The data recorded included patient gender, age, etiology, method of surgical treatment, drug use, and short-term complications. The radiographs were evaluated with
Results
A higher prevalence of trauma was observed in Caucasian (55%) men (89%). The patients’ mean age was 27 years (range, 16 to 62 years), with some type of drug addiction (alcohol, intravenous, and nonintravenous drugs) (62%), and dentate (52%). The majority of fractures in this study were sustained in altercations (39%), followed by motor vehicle accidents (27%). Patient demographic data are shown in Table 1. No relevant medical history affecting bone healing, notably diabetes, prolonged steroid
Discussion
Fractures of the mandibular angle account for the highest percentage of mandibular fractures in many studies. The angle of the mandible is associated commonly with fractures, for several proposed reasons, including the presence of the third molar. Consistent with Ugboko et al20 and differing from other studies,8, 21, 22, 23, 24 the results of this study did not confirm an increased risk of angle fractures when the mandibular third molar was present (55%); patients reported the extraction of
