Surgery and radiation therapy are de main treatments for head and neck cancer. The side effects of the interaction of ionizing radiation on the tissues include dermatitis, mucositis, xerostomia, candidiasis, dysgeusia, dysphagia, caries, trismus, osteoradionecrosis. OBJECTIVE: To assess dental condition of the patients using a protocol which allows avoiding or reducing the effects of radiation in the tissues of the oral cavity. MATERIALS AND METHODS: Dental follow-up was performed before, during and up to 180 days after radiation therapy in 12 patients submitted to surgery and radiation therapy or radiation therapy alone. RESULTS: The proportion of effects such as dermatitis, mucositis, dysgeusia, and dysphagia increased from the second week of the treatment until the end of the administrations. There was a clear decrease at the end of the treatment which was close to baseline values after 180 days. The reduction of xerostomia was slower and less effective. No case of caries, trismus, and osteoradionecrosis were observed during the assessment period. CONCLUSION: Regular dental follow-up associated with preventive measures such as prophylactic management of dental and oral diseases, adequate hygiene, mouth-washing with bicarbonate water and chamomile tea, and topic fluorine application contributed to improve the recovery conditions of patients with cancer of head and neck submitted to radiation therapy.
