ABSTRACT
OBJECTIVES:
We retrospectively evaluated the impact of mandibular third molars on the occurrence of angle and condyle fractures. MATERIALS ANDMETHODS:
This was a retrospective investigation using patient records and radiographs. The sample set consisted of 440 patients with mandibular fractures. Eruption space, depth and angulation of the third molar were measured.RESULTS:
Of the 144 angle fracture patients, 130 patients had third molars and 14 patients did not. The ratio of angle fractures when a third molar was present (1.26 1) was greater than when no third molar was present (0.19 1; odds ratio, 6.58; P<0.001). Of the 141 condyle fractures patients, the third molar was present in 84 patients and absent in 57 patients. The ratio of condyle fractures when a third molar was present (0.56 1) was lower than when no third molar was present (1.90 1; odds ratio, 0.30; P<0.001).CONCLUSION:
The increased ratio of angle fractures with third molars and the ratio of condyle fractures without a third molar were statistically significant. The occurrence of angle and condyle fractures was more affected by the continuity of the cortical bone at the angle than by the depth of a third molar. These results demonstrate that a third molar can be a determining factor in angle and condyle fractures.
