Endodontic management in a rare variant of maxillary third molar with two palatal roots and root canals: a case report

Abstract

The maxillary molars, especially the third molars, have the most complicated root canal system in permanent dentition. There are many variations in root canal number system and configuration in maxillary molars. It is imperative and paramount for the clinician to seek out every possible aberration of root canal anatomy for all teeth undergoing treatment. This paper relates a case of a maxillary right third molar with a canal configuration rarely reported in the literature. The tooth had four roots with four root canals, two separate palatal roots (mesiopalatal and distopalatal) with their own distinct canals and orifices. The mesiobuccal and distobuccal roots had normal anatomy. This paper escalates the complexity of maxillary molar variation and is intended to brace clinician’s awareness of the rare morphology of root canal system.
