Introduction: The thorough knowledge of the internal anatomy of tooth is one of the determining factors for the success of endodontic treatment. Three-rooted second maxillary premolars represent a rare occurrence during endodontic treatment, making its description in the literature an important contribution. This paper describes the endodontic treatment of maxillary second premolar with three separated root canals. Case report: The patient exhibited a right maxillary second premolar affected by continuous pain that was exacerbated by cold testing. Periapical radiograph analysis suggested the presence of three separated roots, which was confirmed during the careful access to the pulp chamber. The tooth was treated with manual instrumentation technique and filled through lateral condensation technique. One and two-years follow-up visits revealed absence of clinical and radiographic signals. Conclusion: The presence of three root canals in second maxillary premolars may compromise endodontic treatment success. Meanwhile, a conscious knowledge of anatomy and a careful diagnosis do not exclude the treatment of anatomic variations by a general dentist without the use of technological resources.
