Mandibular first molar having an unusual mesial root canal morphology with contradictory cone-beam computed tomography findings: a case report.

摘要

INTRODUCTION: 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.
