Morphological changes in teeth may adversely affect the success of endodontic treatment. The upper lateral incisors are characterized by the presence of a canal and a single root. Several studies have reported variations in the number of roots and canals. A careful interpretation of radiographs under enhanced illumination and magnification is of extreme importance for detecting these anatomic variations. this report aimed to describe a clinical case of unusual endodontic retreatment of an upper lateral incisor with two roots. The operative microscopy played a fundamental role in accomplishing the new treatment. The procedure involved the use of solvents, manual files, and ultrasonic tips to remove the obturator, and instrumentation of root canals with stainless steel type K manual files. Root canals were obturated with gutta-percha and Pulp Canal Sealer cement using the thermoplastic technique. : A favorable prognosis was confirmed after a follow-up of 216 months.
