title: Unusual maxillary first molar with 2 palatal canals within a single root: a case report.
abstract: A case report is presented regarding a maxillary first molar with 5 canals. The morphology is atypical because it is characterized by a single palatal root with 2 canals with separate orifices joining in the apical third. A literature review pertaining to the morphology of maxillary first molars is discussed. Modifications to the normal access opening and examination of the pulpal floor for additional canals are stressed.
