The radix entomolaris and radix paramolaris: An endodontic challenge

Abstract

Success of endodontic treatment depends on the proper identificationof all the canals, thorough chemomechanical preparationfollowed by three-dimensional obturation with hermetic seal.Failure of any of these steps may occur due to unusual toothmorphology. Usually mandibular molars have two roots withthree canals but in few teeth, the number of roots and canalsvary. The variation in the number of roots, if extra root locatedlingually called radix entomolaris (RE) or located bucally calledradix paramolaris (RP). This article presents successful endodontictreatment of two mandibular first molars with extra rootsone is with radix entomolaris and other is with radix paramolaris,both of which are rare microstructures.
