Maxillary first molar with seven root canals diagnosed with cone-beam computed tomography scanning: a case report

Abstract

Introduction: The purpose of this article was to emphasize the importance of having a thorough knowledge about the root canal anatomy.

Methods: This case report presents the endodontic management of a maxillary first molar with three roots and seven canals. The clinical detection of the seven canals was made using a surgical operating microscope and confirmed using cone-beam computed tomography (CBCT) scanning.

Results: CBCT axial images showed that both the palatal and distobuccal root have a Vertucci type II canal pattern, whereas the mesiobuccal root showed a Sert and Bayirli type XV canal configuration.

Conclusion: This report describes and discusses the variation in canal morphology of maxillary first molar and the use of latest adjuncts in successfully diagnosing and negotiating them.
