Two Rooted Mandibular First Molar with Three Distal Canals - A Case Report

Background: The Mandibular first molar is the tooth that requires root canal treatment most often. It usually has two roots with two canals mesially and one or two canals distally. A mandibular first molar with more than four canals represents a rare anatomical variation, especially when the three canals are found in distal root. With increasing reports of aberrant canal morphology, the clinician needs to be aware of this varied anatomy. This case report discusses endodontic management of 2 rooted mandibular molar with 3 distal canals (disto-buccal, middle-distal, disto-lingual) and 2 mesial canals.
