Introduction: In addition to the use of materials and techniques to promote the endodontic treatment success, it is essential the knowledge of the internal anatomy of the pulp cavity because the changes in relation to the number, direction, appearance, size, and section may interfere with the cleaning and shaping process, including the mandibular bicuspid, which may have three canals, and its occurrence represents a very difficult clinical situation to the dentist. Objective: The purpose of this clinical case report is the description of the endodontic treatment of a mandibular bicuspid with three root canals, which highlights the need for knowledge of the anatomic variations present at this dental group and the difficulties that this situation imposes for its realization. Methods: In the endodontic treatment of a first mandibular premolar, with three root canals, was carried out, after the coronal opening, the exploration of the root canals and it was possible to identify the existence of three canals. Next, we proceeded to the biomechanical preparation through inverted mixed technique and the case was completed with the obturation by the lateral condensation technique. Conclusion: The complexity of the mandibular first premolar anatomy is responsible for many cases of clinical failure, whereas in some cases these teeth have more than two root canals, which are difficult to identify. In this respect, the knowledge of tooth anatomy and the use of diagnostic tools represent great importance regarding the efficiency of the treatment.
