Third molar position as predisposing factor for mandible angle fracture

ABSTRACT

The aim of the study was to assess the position of 3rd molar as a predisposing factor in the fracture of the mandible at the angle. Age and sex distribution was also studied. Out of 125 mandibular fractures at the angle, during a study from 1991-97 at Khyber College of Dentistry, Peshawar, 108 [86.4%] cases had 3rd molar present while in 17 [13.6%] cases it was absent. In 108 angle fractures, 23[18.4%] were fully erupted, 42[33.6%] were partially vertically erupted, 3[2.4%] were partially erupted distoangular, 15[12%] partially erupted mesioangular, 13[10.4%] were unerupted vertically, 7[5.6%] were unerupted mesioangular and 5[4%] were unerupted horizontally. High prevalence was seen in the third decade i.e.46%. Male to female ratio was 41
