Teeth harbor complex root canal systems that commonly communicate with the attachment apparatus furcally, laterally, and often terminate apically into multiple portals of exit. It is critical to respect the mechanical objectives for preparing canals.

Shaping facilitates cleaning and disinfection, and promotes filling root canal systems in three dimensions.
