During the 6-month period from mid February 1988 to mid August 1988, 148 patients presented with 154 diagnosed cases of mandibular third molar pericoronitis. All patients were members of the recruit population stationed at the Recruit Training Command, Great Lakes, Illinois. Selected clinical parameters relating to the orientation and eruption status of these third molars were collected and analyzed. ⋯ In the population studied, risk for pericoronitis appears to increase with greater vertical orientation and height of eruption. The absence of impinging maxillary dentition did not eliminate the risk of mandibular third molar pericoronitis. These data have implications for targeting treatment needs of naval and Marine Corps personnel who may be without dental support for extended periods of time.
