Efeitos da radioterapia em região de pescoço na cicatrização após extrações dentárias: relato de caso

Abstract

Radiotherapy is one of the forms of treatment for cancer, since the destruction of tumor cells, however, ends up happening, even causing damage or death to normal cells. Some of the oral repercussions of radiotherapy are xerostomia, oral mucositis, hypogeusia, osteoradionecrosis (ORN), among others. This study aims to report the case of a patient with a previous history of therapy in the neck region, who presents the healing time of the mucosa after the extraction of the lower teeth, which took place at the clinic for special needs of the Dentistry Course of the Federal University of Ceara (UFC). Noting this fact, to avoid the risk of ORN, some sessions were presented with low power LASER, until complete healing of the mucosa, where the LASER protocol suffered variation due to the tooth, use of photosensitizing agent and daily assessment of the healing process. On tooth 35, 4 sessions of PBMT were performed; on tooth 46, 3 sessions of PBMT and 2 sessions of PDT were performed, with 2 sessions being performed after three months of PDT of bone spicule on the tongue board; while on tooth 48, 6 sessions of PDT were performed. With this, it is noted the need for the dentist to be attentive when caring for previously irradiated patients, due to the risk of ORN, requiring some special care in order to reduce post-surgical sequelae.
