New classification for pulp chamber floor anatomy of human molars.

Comprehensive knowledge of the entire root canal system is an essential prerequisite for successful routine endodontic treatments. The internal and external morphological configurations of roots and root canals are quite complex. Thus, several classifications have been put forth by researchers to appropriately understand the distinguishable features of root and root canal systems of multirooted teeth. Until now, the researchers have proposed new classification systems for a thorough understanding of the root canal systems, mainly concentrating on the root canal anatomy and anomalies. Moreover, with the advent of newer digital imaging systems, these classifications are more reproducible and relevant. They have further gained importance for the clinicians by acting as an aid in decision-making based on evidence-based dentistry. However, these classifications are primarily focused on the root canals, but none have assessed the anatomy of the pulp chamber floor. This review article delineates a novel Pawar and Singh molar pulp chamber floor classification© for the anatomy of maxillary and mandibular molars to ease the clinician's skills and further increase the prevailing literature for the benefit of researchers.
