Cirurgia do periápice associada a enxerto com biomaterial : estudo de caso.

Abstract

Periapical surgery belongs to endodontic surgeries’ discipline. It’s considered a treatment option in cases of teeth affected by chronic apical lesions, in which the conventional endodontic treatment can’t be executed or when it evidences failure. The surgical method allows to remove the pathologic tissue, resulting in a conduit without exudate and a regeneration of supporting tissues. In this case study, the periapical surgery was performed on the tooth 22 of a male patient. He had fistula and an extensive intra-root core. In that surgical procedure, the pathologic tissue was removed and, along the procedure, bone graft made of biomaterial (OsteoGen®) was used in order to achieve an improvement in the bone repair. The patient was advised to return to university’s Ontological clinic to clinical and radiographic attendance every 3 months. The goal of this work is to evaluate the regeneration of bone tissue and the involution of lesion after the curettage of apical lesion jointly with biomaterial graft, in order to preserve the tooth in the mouth. Based on clinical and radiographic control, we can conclude that insertion of biomaterial on the bone cavity was effective in healing of bone defect. However, we can realize tooth’s resorption, and it may indicate bacterial presence.
