Maxillary first molar with five canals

Abstract

Maxillary first molar usually has three roots namely, mesiobuccal, distobuccal, and palatal. The incidence of four canals in maxillary first molar ranges from 50.4% to 95%, the fifth canal is 2.25%, and few authors have reported cases with six and seven canals too. With this varying number of canals and canal configurations, endodontic treatment of the maxillary first molars is always a challenge. This clinical article describes a case report of a maxillary first molar with the unusual anatomy of five root canals and its endodontic management.
