Endodontic Access Cavity Preparation

INTRODUCTION :

A well-designed access preparation is essential for a quality endodotic result.

The objective of an access preparation is to create a smooth, straight-line path to the canal system and ultimately, the apex.

Careful cavity preparation and cavity obturation are the keystones of ideal root canal therapy success.

Access preparation may be divided into visual and the assumed. The coronal anatomy is the first indication of the assumed and is the first key to the root position and root canal system. Before entry, the clinician must visualize the expected location of the coronal pulp chamber and canal orifice position to avoid unnecessary tooth removal.
