AN UNUSUAL CASE OF BILATERAL INFLAMMATORY external/internal root resorption developed in the maxillae of a 28 year-old female approximately 4 years following routine segmental orthognathic surgery. The patient experienced dental pain in a tooth adjacent to a segmental osteotomy cut 8 months postsurgery, however, the tooth later became asymptomatic. A definitive diagnosis of inflammatory cervical root resorption was not established until nearly 4 years later on routine dental examination. The external/internal resorptive lesions were located 4 to 6 mm apical to the connective tissue attachment on 3 of the 4 tooth roots adjacent to osteotomy cuts. Two of the affected teeth required non-surgical root canal therapy due to pulpal communication with the resorptive defects. The lesions were accessed by flap surgery, thoroughly debrided, and obturated with an intermediate restorative material until definitive restorative therapy could be completed. All sites healed uneventfully and the patient has been closely observed for approximately 2 years without symptoms or recurrence of the resorptive lesions. Dental health care providers should be alert to the possible occurrence of inflammatory root resorption in sites adjacent to osteotomy cuts over extended periods of time. Routine radiographic examination may be beneficial in the postoperative management of the segmental orthognathic surgery patient.
