The endodontic treatment aims a correct instrumentation, cleaning and modeling of the root canal having a complete removal of necrotic tissues and bacterial infiltration. Procedural failures and intercurrences may be related to the emergence of therapy failures, requiring retreatment. In this way the present study aimed to report the endodontic retreatment in a patient with extensive periradicular lesion and presence of root perforation in the middle / cervical thirds. Retreatment of 21, 22 and 23 teeth were performed through the use of ultrasonic inserts and rotational instrumentation, It was possible to detec perforation in the cervical and middle third region of element 22. The perforation treatment was performed using the operating microscope, with adequate decontamination and MTA filling. It was followed for 6 months. After this period we can observe signs of neoformation of the bone matrix in the region affected by the lesion and the patient presented asymptomatic.
