A method to minimize complications in endodontic access cavity preparation.

Today's FDA : official monthly journal of the Florida Dental Association, 2008
This article presents a method of avoiding some operative errors in endodontic-access cavity preparation. Utilizing the radiograph, a line representing the coronal extension of the image of the coronal two-thirds of the root canal(s) is drawn on the facial surface of the crown (Fig. 1).
