INTRODUCTION: Endodontic surgeries contribute to the resolution of complications resulting from conventional endodontic treatment. Root resection, a type of endodontic surgery, consists of partial root removal followed by canal preparation and filling with adequate material. In case of perforations, mineral trioxide aggregate (MTA) has often been used for retrograde sealing of the root canal, which prevents microorganism infiltration and byproducts. Moreover, MTA is a biocompatible material that adheres and adapts to the walls after preparation, it is insoluble in tissue fluids and dimensionally stable. METHODS: This report describes a case of conservative treatment of tooth #26 whose mesiobuccal canal was perforated during endodontic treatment, with probable change of internal canal anatomy. Mesiobuccal root cervical third resection was recommended. RESULTS: At one-year follow-up, root end resection and MTA sealing showed satisfactory clinical and radiographic results. Additionally, the treated tooth was asymptomatic and functional. CONCLUSION: Root resection and sealing using MTA repaired endodontic perforation, suggesting this technique may be used in similar cases with a good chance of success, thus avoiding premature tooth loss.
