Dental extractions in relation to radiation therapy of 224 patients.
The case histories of 224 patients treated with radiation therapy for head and neck malignancies at the Radiotherapy Clinic of the University Central Hospital in Turku during the years 1974-77 are reviewed. Of the 92 patients surviving for 5 years, 90 were available for re-examination. The median radiation dosage was 61 Gy in 6 to 8 weeks in patients with squamous cell carcinoma and other solid tumours and 43 Gy in 5 weeks in patients with lymphoma. The oral status of the patients was examined clinically and radiographically. From these patients, 45 teeth had been extracted before irradiation and 94 after irradiation. In no case had this resulted in osteoradionecrosis of the jaws. It is evident that the repairing of patient's teeth before radiation treatment, coupled with continuous preventive care of caries, will prevent serious complications from arising.
