Morphologic Variations of Maxillary Molars Palatal Root and the Importance of Its Knowledge for Endodontic Practice: A Case Series

Abstract

ABSTRACT Aim The present report describes and discusses root canal variations in the internal morphology of maxillary molars. Background Dental internal anatomy is directly related to all the technical stages of the endodontic treatment. Even though, in some situations a typical anatomical characteristics can be faced, and the professional should be able to identify them. Case descriptions This clinical report describes five cases with different pulpar and periapical diagnostics where the endodontic treatment was performed, in which during the treatment the unusual occurrence of two or three canals in the palatal root ‘or even two distinct palatal roots’ of first and second maxillary molars, were described and important details for achieving treatment success were discussed. Conclusion The knowledge of tooth internal anatomy must be considered during clinical and radiographic examinations. This should be valued not only to find atypical canals but also to enable calcified canals cleaning and shaping, once they are frequently omitted during endodontic therapy. Clinical significance Anatomic variations can occur in any tooth, and palatal roots of maxillary first and second molars are no exception. The complexity of the root canal system and the importance of identifying its internal anatomy for planning endodontic treatment increase the chances of success.
