[Systematic preservation of teeth and prophylaxis of dental decay on irradiated patients]

200 patients were irradiated on the oral cavity and on salivary glands with doses of 3,000 Rads and up. Teeth were preserved. A prophylactic treatment of dental decay was made using 5 minutes daily a fluoride gel into a carrier. The results showed an incidence of 5% for dental decay and 1% for osteo-radionecroses. Details are given about the selection of patients, the dental work-up and dental care before, during and after radiation therapy.
