Endodontic Management Of A Rare Case Of Maxillary First Premolar With Three Root Canals Using Dental Microscope: Case Report

Aim: The aim is to report the diagnosis and successful endodontic management of patient with anatomical variation in maxillary first premolar.

Summary: Maxillary 1st premolars have variable root canal morphology. Although it usually has two canals, it may rarely have three and this third canal can easily be missed. Thus meticulous knowledge of tooth morphology along with careful interpretation of angled radiographs, proper access cavity preparation and a detailed exploration root canal is needed to ensure a proper endodontic treatment. This article reports a rare finding of three canals in a maxillary first premolar with non well defined root outline radiographically during an elective root canal treatment.
