Complexity and Variability of the Endodontic System - Evolution of Root Canal Morphology Classification Systems

As stated by The American Association of Endodontists [1], the primary objective of endodontic treatment is to prevent and intercept pulpal/periradicular pathosis and to preserve the natural dentition when affected by pathosis.To achieve this goal, a thorough knowledge of the endodontic system is to be considered.This also implies having the best possible means to classify and communicate the intricate root canal morphology, in term of number of roots, root canals, root canal orifices and apical foramens.
