Identification of independent middle mesial canal in mandibular first molar using cone-beam computed tomography imaging

Abstract

Introduction: The root canal treatment of a mandibular molar with aberrant canal configuration can be diagnostically and technically challenging.

Methods: This case report presents the clinical management of a mandibular first molar with three separate mesial canals including middle mesial canal, which was confirmed by cone-beam computed tomography (CBCT) images.

Results: Posttreatment images revealed three independent root canals in the mesial root obturated efficiently to the accepted lengths in all three canals.

Conclusion: This case report highlights the usefulness of CBCT imaging for accurate diagnosis and management of the unusual canal morphology.
