Endodontic management of a maxillary first molar with three roots and six root canals.

Variations in the root canal anatomy of a maxillary first molar are often challenging to diagnose and treat; thus, clinicians must have a thorough knowledge of the same. This case report highlights the successful nonsurgical endodontic management of a maxillary first molar with an unusual morphology of three roots and six root canals. A total of six root canals (mesiobuccal [MB] 1, MB2, MB3, distobuccal [DB] 1, DB2, and palatal) were detected after initiating root canal therapy and access cavity preparation. Conventional root canal treatment was completed, and postoperative cone-beam computed tomography scanning was done to verify the total number of canals and ensure the adequacy of root canal fillings. Managing such cases with rare variations in the root canal systems could be arduous and thus, clinicians should be well-versed in the methods to identify and manage such complexities to facilitate the successful outcomes of endodontic treatment.
