Effects of Ionizing Radiation in the Human Oral Cavity and Oropharynx

Abstract

Recognition of the existing controversy over the use of oral prostheses in patients treated for malignant tumors of the head and neck led to the formulation of a questionnaire for radiotherapists and prosthodontists. The purpose of the survey was to compare the opinions of two disciplines on the management of the oral cavity after megavoltage therapy. The survey attempts to obtain the opinion of therapeutic radiologists and prosthodontists as to whether or not intraoral prosthesis might increase the incidence of osteoradionecrosis in patients who have received radiotherapy to the oral region. Questions related to response of the oral mucosa to therapeutically administered radiation, as well as questions on the effects of varying absorbed doses, are included. Paterson (10) believed that a necessary consequence of irradiation in malignant tumors of the head and neck was a certain incidence of osteoradionecrosis and that it could only be prevented by inadequate dosage. It is usually accepted that trauma and ...
