Mandibular first molar having an unusual mesial root canal morphology with contradictory cone-beam computed tomography findings: a case report.
BACKGROUND
The objective of this article is to highlight the importance of having a thorough knowledge about the root canal anatomy and the possibility of misleading findings in the cone-beam computed tomography (CBCT) images.


METHODS
This case report presents the endodontic management of a right mandibular first molar with 2 roots and 2 canals. A CBCT imaging was performed to ascertain this rare root canal anatomy.


RESULTS
The clinical and radiographic diagnosis of the existence of a single root canal within the mesial root of mandibular first molar did not correlate with the CBCT findings.


CONCLUSIONS
The confirmative diagnosis should be based on cognitive deduction of the clinical picture and intelligent interpretation of radiologic information.
