Abstract : The success of root canal therapy depends on cleaning of all the infected root canals and three- dimensional hermetic seal of the canals. For this, the knowledge of the root canal anatomy plays a vital role. However, the root canal anatomy is not always predictable. It is complex due to various anatomic variations and recognizing it and cleaning it thoroughly is a challenge to clinicians. This case report presents root canal treatment of unusual anatomy of maxillary first molar with six root canals, two mesio-buccal, two disto- buccal and two palatal canals.

Keywords : Disto-Palatal, Maxillary First Molar, Mesio- Palatal, Six Canals.
