Root Canal Components

Essentially, the root canal system can be divided into pulp chamber, located within the anatomic dental crown, and the root canal space, found inside the radicular portion of the tooth. Other important components of the internal anatomy of teeth include canal orifices, apical foramina, apical ramifications, and accessory, lateral, and furcation canals. The purpose of this chapter is to describe common features of the internal anatomy in all groups of teeth, and, in addition, to provide brief comments on its impact on diagnosis and clinical procedures.
