In root canal treatment, the foundation on which all surgical procedures are performed is a thorough knowledge of the anatomy of the pulp chamber and the root canal system. The endodontic triad comprises biomechanical preparation, microbial control and complete obturation of the root canal space. Knowledge of the pulp chamber floor anatomy is important in locating the numbers and orifices of root canals present within the tooth being root canal treated. This is particularly important while treating teeth that are heavily restored, mal-positioned, or calcified. The current review attempts to explain the complex anatomy of the pulp chamber floor and its significance in root canal treatment.
CPD/Clinical Relevance: To allow the location of all root canal orifices in the pulp chamber and to perform successful root canal treatment, knowledge of pulp chamber floor anatomy is essential. The clinician should consider that, as the external morphology of the tooth varies in individuals, so does the internal morphology.

The pulp complex should be visualized as beginning occlusally at the pulp horns and ending at the apical foramina. In order to remove pulp tissue entirely from the pulp complex, the coronal portion must be accessed in a manner that will permit pulp removal and facilitate the location and debridement of the root canals without unnecessarily compromising the strength of the coronal enamel and dentine. The variation of the pulp chamber floor, especially in multi-rooted teeth, is a constant challenge for diagnosis and subsequent root canal treatment.1 Attempting to treat the root canal system without detailed anatomical information could be potentially disastrous. There is an abundance of literature describing root canal anatomies, but the studies that have considered pulp chamber anatomy have been very generic and offer little insight on how to determine the orifice number and location of root canals.2
