PortuguêsAbstract
The maxillary first molar has the highest failure rates in endodontic treatment due to the high prevalence of a fourth canal, the mesiobuccal 2 (MB2) canal. Failure to locate or properly treat this canal often results in treatment failure. Objective: To report a case of endodontic treatment in a maxillary first molar with MB2 and highlight the importance of identifying and treating the fourth canal, along with discussing potential anatomical variations. Case Report: A 37-year-old female patient presented at the Dental Clinic of the Postgraduate Course in Endodontics at IOA – Chapecó/SC, referred by the Esthetics Course, with complaints of severe pain in a left maxillary tooth. After anamnesis, clinical and radiographic evaluation, and sensitivity tests, a diagnosis was established, indicating endodontic treatment of the maxillary first molar (tooth #26). The treatment was completed in three sessions. In the first session, the main canals were prepared, and the MB2 canal was located. Subsequent sessions focused on further preparation and the complete obturation of the root canal system. Final Considerations: Dentists performing endodontic treatments must thoroughly understand root canal anatomy and its variations. Staying updated on current technologies that assist in planning and executing treatments is crucial for achieving favorable prognoses and high success rates. Proper localization of canals during the initial treatment minimizes the need for retreatments, thus enhancing the overall success of endodontic therapy.
