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.

Key Words: Cone beam computed tomography imaging, mandibular molar, middle mesial canal
