Abstract
Background and OverviewThe purpose of this article is to present the variations in maxillary molar palatal root canals and provide a reference for the possible variations in root canal treatment. Case DescriptionFive rare cases with palatal canal variation presented in this case series received nonsurgical endodontic treatment successfully. These case reports highlight that understanding and managing the different types of canal configurations in palatal roots of maxillary molars is essential to successful root canal treatment. We tried 2 methods of examining the palatal canal variation to provide examples for clinicians in diagnosing and treating similar cases. Conclusions and Practical ImplicationsThe outline form of the access cavity and the shape of the pulp chamber floor are important factors for identifying variations in root canal number. Moreover, cone-beam computed tomography can help in detecting variations in root canals.
