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). This line determines the proper angulation of the bur to facilitate entry into the pulp chamber in proper mesio-distal orientation, thereby reducing the likelihood of mesial and distal gouging and perforating. Marking the tooth to be treated prior to rubber-dam placement help in preventing treatment of an incorrect tooth. Two studies utilizing Nova Southeastern University College of Dental Medicine (NSUCDM) second-year dental students (D-2), one utilizing University of Florida, College of Dentistry (UFCD) second year dental students (D2) and one utilizing NSUCDM Advanced Education in General Dentistry (AEGD) faculty and students were undertaken to evaluate the method. Evaluation was by endodontic teachers. Results indicate use of the line-drawing method may facilitate more ideal access cavities than those prepared without the method. Welch's t-test, chi-square test and estimating equations were employed. One study showed significant difference between control and test groups (p less than 045). All studies indicated a difference. Further testing of the method is indicated. This valuable tool should be considered for use in teaching and practice.
