Abstract

Endodontic retreatment is a procedure performed on a previously treated tooth, which for some reason was unsuccessful, presenting clinical and/or radiographic repercussions and which can be performed in a single session when well indicated. One of the signs that there has been an irregularity is the presence of an intraoral fistula, which suggests persistence or recurrence of an infection in the periapical tissue. The objective of this work was to present a clinical case of endodontic retreatment in a birooted tooth with intraoral fistula, in which the patient T.M.B.C, female, attended the Clínica Escola de Postgraduate em Odontologia da Faculdade do Amazonas (IAES) with a main complaint of “a little ball on top of the tooth” that had lasted 3 to 4 weeks. Radiographic examinations and fistulography were performed to identify the origin of the infection. The system of choice for retreatment was PRO T from MK Life, with the aid of the Motor Easy Bassi iRoot® endodontic motor and Finepex Schuster® apical locator using the instrumentation sequence S2, F1, F2 and F3 (Pro T – MK Life), alternating with hand files type K #10 and #15 (Dentsply®) with the working length of the canals being buccal 19 mm and palatal 18 mm, with 2.5% sodium hypochlorite irrigation (Asfer – Brazil) and aspiration. It is concluded that the technique used was effective as it promoted the preservation of the affected tooth, contributing significantly to improving the patient's quality of life.
