Enxerto de tecido conjuntivo subeptielial para recobrimento radicular em paciente submetido à radioterapia

Abstract

Radiotherapy (RT) is one of the treatments capable of causing changes at the cellular level and preventing the replication of cancer cells. It is currently widely used in cancer treatment in general. However, it brings a series of complications to healthy tissues due to its non-specificity, especially when administered in the head and neck region, it causes several dental complications to the patient. This study sought to evaluate the effectiveness of subepithelial connective tissue grafting in a patient irradiated with low doses of RT for the treatment of Hodgkin's Lymphoma. Using the Langer&Langer technique, the furcation region associated with gingival recession of a maxillary first molar was covered with a subepithelial connective graft obtained from the palate region after basic periodontal therapy. No postoperative complications were observed, a control and a 90-day periogram reevaluation was performed, where partial root coverage of the recession was noted. In this way, root coverage of extensive gingival recession and furcation involvement can improve the prognosis and contribute for stabilization and maintenance of the teeth in function, in addition to avoiding the need for extractions and the risk of developing osteoradionecrosis ORN.
