Endodontic management of maxillary first molar with an anatomical variation of two palatal canals: A case report

An in-depth knowledge of the root canal anatomy is important for any successful root canal treatment; however, complexities exist within the root canal morphology. The maxillary first molar has variations in its root morphology and canal configurations. In literature, this variation is only observed in an estimated 1.12%-1.17%. One such case is described in this case report which provides the endodontic management of a left maxillary first molar with two palatal canals using loupes magnification.

Management of maxillary first molar with six canals using operating microscope

The purpose of this article was to highlight the importance of having a thorough knowledge about the root canal morphology. This case report highlights the unusual anatomy of a maxillary first molar with three mesiobuccal (MB) canals, two palatal canals, and one distobuccal canal which is extremely rare. The use of operating microscope was crucial, both for the detection and for the management of the additional canals. The use of surgical operating microscope and digital radiograph showed that MB root had Type 3-1 of Gulabivala classification and palatal canal showed Vertucci's Type II canal morphology This report describes and discusses the identification of variation in canal morphology of maxillary first molar and the use of latest adjuncts in successfully diagnosing and negotiating them.
