TEODORO, Maria Kaline Romeiro et al. Success of periradicular surgery in persistent endodontic infection resolution with CT control of 2 years. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2014, vol.14, n.4, pp. 71-76. ISSN 1808-5210.

This case report aims to describe and discuss the treatment of a right maxillary central incisor tooth, endodontically treated, with presence of an internal root resorption and periradicular radiolucency. On clinical examination the patient presented a sinus tract at the apical buccal mucosa of this tooth. The periapical radiograph and cone beam computed tomography detected the presence of radiolucent area inside root canal (apical third). This area showed to be inaccessible to adequate chemical-mechanical preparation, so, the endodontic retreatment would give an uncertain prognosis. Thus, the periradicular surgery was the indicated therapy for this case, including apicectomy, retropreparation and root canal retrofilling, with the use of appropriated ultrasonic inserts and Mineral trioxide aggregate (MTA), respectively. After two years of follow-up, the endodontic infection control was observed. The treatment was considered a success, as the patient was asymptomatic, with no sinus tract and with complete regression of periapical radiolucency and bone formation. It can be concluded that the periradicular surgery was an effective treatment for the patient, allowing a degree of disinfection compatible with periradicular cure.
