Mandibular permanent first molar with six conduits – A case report.

Success in the non-vital pulpal therapy in permanent teeth can be achieved after a complete and thorough cleaning and shaping of all the canals and achieving hermetic seal through restoration of those prepared canals. This clinical case describes the unusual morphological configuration of the root canals in the mandibular permanent first molar. This case report adds to the available literature on various anatomical variations in the root canal system of mandibular first molars and emphasizes the importance of dealing with rare morphological variations while performing pulpal therapies to have a successful outcome in them.
