Maxillary First Premolar with Three Root Canals: A Case Report

Abstract

The maxillary first premolar is the most commonly bi- rooted tooth with  occasional presentation of three roots system; it is a transitional tooth  between incisors and molars. 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, careful interpretation of angled radiographs,
proper access cavity preparation and a detailed exploration of the interior of the tooth 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.
