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


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