title: Osteoradionecrosis related to mastication and parafunction.
abstract: This article discusses mastication and parafunctional habits as possible etiologic factors in the development of osteoradionecrosis. From the three case reports presented it was noted that bone necrosis can occur after extended periods after radiation therapy, is seen most frequently in the mandible, and occurs most often at dosage levels exceeding 6500 rad. Recommendations after treatment to patients receiving 6500 rad or more should include caution regarding consistency of diet, use of existing prostheses, and the potential harmful effects of parafunctional habits.
