ABSTRACT
The focus of this article was to highlight the importance of having a thorough knowledge about the root canal anatomy and treating the tooth successfully. This article presents the management of a maxillary first molar with three roots and seven canals with the detection of the seven canals using cone-beam computed tomography (CBCT) scanning. The palatal and disto-buccal roots have a Vertucci type II canal pattern and the mesio-buccal root shows a Sert and Bayirli type XV canal configuration. This article describes and discusses the different variation in canal morphology of maxillary first molar and the use of latest development in technologies in successfully diagnosing and treating them.
