Mandibular premolars with aberrant canal morphology: An endodontic challenge

Abstract

Complete cleaning and shaping is the key to successful endodontic treatment. A thorough understanding of the internal anatomy and morphology of the root canal system is an important consideration when performing cleaning and shaping procedures. Mandibular premolars are one of the most difficult teeth to treat endodontically because of aberrant root canal anatomy. This article describes case series of mandibular premolars with variations in root canal anatomy treated successfully by conventional endodontic treatment.
