Objective: to report a clinical case of root perforation, caused by iatrogeny in the cervical and middle third of an upper central incisor, tooth 21, with presence of periapical bone lesion. Case report: clinically, there was no edema and fistula. Facing the evaluation of the pulp condition and the periradicular tissues, the tooth presented pain on palpation, absence of mobility and pain on vertical and horizontal percussion. After the imaging exams, obtained by cone-beam computed tomography (CBCT; Prexion 3D), extensive periradicular lesion, obliterated root canal and root perforation were observed in the buccal face after attempted surgical access. As a choice of treatment, we chose to recover the original path of the canal in order to obtain intracanal access, chemicomechanical preparation and obturation by the single-cone technique to later promote proper sealing of the perforation with MTA Repair HP (Angelus, Londrina, PR, Brazil). After six months, the tooth was asymptomatic and, radiographically, the repair of the periapical lesion was observed. Final considerations: the correct planning, knowledge of the materials used and therapeutic approach were of paramount importance for the proper management of the case.
