Methods: The clinical data of 37 patients with mandibular angle fracture admitted between Jan 1987 to Aug 1999 were analyzed, which focused on the cause of fracture. Results: Of 37 patients, occlusion and masticatory function was normal. The third molars on the line of fracture had important effect on the mandibular angle fracture.Conclusion: The strength, direction and position of the force were the decisive factors of the mandibular angle fracture. The presence and position of the mandibular third molar may be risk factors for angle fracture.
