Resumo
Tema: cirurgia, radioterapia e quimioterapia são as modalidades terapêuticas usadas no tratamento de câncer bucal. Podem ser usadas isoladas ou conjuntamente. Radiação ionizante causa lesões nos tecidos normais localizados no campo de radiação. Isto se torna particularmente evidente nas regiões de cabeça, uma área complexa composta de várias estruturas diferentes que respondem diferentemente à radiação. As sequelas orais resultantes podem causar problemas substanciais durante e depois da terapia de radiação e são os maiores fatores de determinação na qualidade de vida dos pacientes. Dentre as complicações da radioterapia estão a xerostomia, osteorradionecrose, mucosite e candidose.
Objetivo: apresentar aos profissionais de saúde uma reflexão sobre as questões pertinentes às sequelas bucais da radioterapia de cabeça e pescoço.
Conclusão: o acompanhamento odontológico sistemático pode minimizar os efeitos da radiação sobre os tecidos da cavidade bucal.

Abstract
Background: surgery, radiotherapy and chemotherapy are therapeutic modalities used in the treatment of oral cancer. They can be used separately or in combination. Ionizing irradiation causes damage to normal tissues located at the radiation field. This becomes particularly evident in the head and neck region, a complex area composed of several dissimilar structures that respond differently to radiation. The resulting oral sequelae may cause substantial problems during and after radiation therapy and are major factors in determining the patient's quality of life. Xerostomia, osteoradionecrosis, mucositis and candidosis are some of radiotherapy's complications.
Purpose: introduce health professionals to reflect on issues relevant to oral sequelae of head and neck radiotherapy.
Conclusion: regular dental follow-up may reduce the effects of radiation in the tissues of the oral cavity.
