A case report on unusual root anatomy: endodontic management of mandibular Second premolar with three canals

Dental anatomical variations play a significant role in the diagnosis and a successful treatment outcome in endodontics. Presence of extra roots and canals should be considered before initiation of  root canal treatment for the success of endodontic treatment. It is essential for the clinician to have a
clear picture and understanding of the pulpal anatomy and its variations. A mandibular second premolar with three separate roots is very rare and its prevalence has been reported to be around 0.1%.The aim of the present article is to report a case about the successful diagnosis, and clinical  management of a mandibular second premolar with two independent roots and three root canals.
