Introduction: The possibility of additional root canals should be considered even in teeth with a low frequency of abnormal root canal anatomy, therefore demanding more attention of the clinician during root canal treatment. Objective: This article reports a relatively uncommon clinical case of a mandibular first premolar with two roots and three canals which was successfully treated with root canal therapy. Methods: After initial radiograph, the presence of two roots was detected. Additional care was taken to explore the root canals, confirming the presence of three canals with the aid of a microscope. The root canals were instrumented using a hybrid rotary technique advocated by the School of Dentistry from Piracicaba, and obturated using Sealer 26 and cold lateral compaction. Conclusion:b> In order to achieve the best possible outcome in root canal treatment it is important to have a good knowledge of the root canal system morphology in addition to appropriately using the diagnostic tools.
