Endodontic Management of a Tooth with Radix Entomolaris and Five Root Canals

Success of endodontic treatment depends on the proper identification of all the canals, thorough chemo-mechanical preparation followed by three dimensional obturation with hermetic seal. Failure of any of these steps may occur due to unusual tooth morphology. The endodontic treatment of a mandibular molar with aberrant canal configuration can be diagnostically and technically challenging. Radix Entomolaris (RE) is one such aberration where an extra root is present on the distolingual aspect of mandibular first molar (molar with 3 roots). This article presents a case report of mandibular first molar with extra distal root and five root canals.
