Revascularization in a maxillary lateral incisor using bioceramic sealer: case report

Abstract

Revascularization is a regenerative endodontic dental procedure, which aims to stimulate the penetration of periradicular tissue inside the root canal, allowing vascularization of necrotic teeth, leading to a tissue repair and regeneration. Currently, Biodentine cement has been used to perform this procedure. The aim of this study was to report a clinical case about the revascularization of a maxillary lateral incisor with incomplete root formation using Biodentine. The patient, male, 10 years old, attended the multidisciplinary clinic of CEULP/ULBRA accompanied by the responsible, asymptomatic, reporting trauma to element 22, sensitivity and vertical percussion tests were performed with negative results. Through periapical radiography, incomplete root formation and a radiolucent area in the periapical region were observed. The revascularization technique was performed, aiming to stimulate the root formation. In the first session, instrumentation with K-type instruments at working length and intracanal medication were performed. After 15 days, the revascularization procedure was performed with a 25/0.02 K file led beyond the working length to stimulate periapical bleeding, so the canal was filled with blood up to the cervical third. Blood clotting was awaited, Biodentine was placed, and the definitive restoration was performed with composite resin. Follow-up up to 1 year and four months was carried out and the root development was observed. Thus, in the reported case, the revascularization technique proved to be efficient, allowing the continuity of the root formation a compromised tooth.
