Endodontic Coronal Cavity Preparation

As you have read before, endodontic preparations deal with both coronal and radicular access, each of which is achieved separately but ultimately flow together into a single preparation. The principles of endodontic coronal cavity preparation (access opening) can be enumerated as:

1) Outline form

2) Convenience form

3) Removal of the remaining carious dentin (and defective restorations), and

4) Cleansing of the cavity.
