Endodontic management of a mandibular first molar with three distal canals confirmed with the aid of spiral computerized tomography: a case report

Oral Surg Oral Med Oral Pathol Oral Radiol Endod. 2009 Oct;108(4):e77-81. doi: 10.1016/j.tripleo.2009.06.017.

Abstract

Identification and treatment of extra canals is the cornerstone to successful endodontic practice. Over the years, many diagnostic aids have evolved to facilitate the clinician in detection of hidden canals and to familiarize with the internal radicular anatomy. This case report highlights the rare incidence of 3 canals in the distal root of a permanent mandibular first molar. A spiral computerized tomography scan was used as a noninvasive diagnostic tool to confirm the diagnosis.
