Endodontic Management Of Aberrant Root Canal Anatomy In Mandibular Premolars

For the success of endodontic treatment, an understanding of root canal anatomy and morphology is very important. Proper endodontic management would require a thorough debridement, disinfection and obturation of the root canal. Mandibular premolars are termed as “enigma to endodontists” as they are believed to possess aberrant root canal anatomies such as multiple root canals, apical deltas and lateral canals. Such aberrant anatomies depend on various factors like ethnic background, age and gender of the population. These variations in anatomies can be identified using various radiographic techniques and under magnification. Failure to identify and disinfect additional canals would result in flare ups and failures. This article reports the aberrant mandibular premolar anatomies and discusses the treatment recommendations for a successful endodontic outcome.
