Maxillary First Molar with Two Palatal Canals: A Rare Case Report

Thorough knowledge of clinician about the internal anatomy and its possible variations is very important for the success of root canal therapy. Variations in the no. of roots, root canals and configurations make the therapy more difficult to perform. Missed and non-negotiable canals during the treatment could affect the outcome of treatment. Clinician should be careful while treating maxillary first molars because of its root curvatures, additional canals and variations in internal morphology. Finding the MB2 canals in the mesiobuccal root is routine. Palatal canal is usually single, large canal which is broad mesiodistally and mirrors the root in which it houses. Rarely there are modifications in palatal canal. This paper presents a rare case report of endodontic management of a maxillary first molar with 2 palatal canals.
