Molar Endo Access: CEJ is your Guide

This is one in a series regarding endodontic access using some of the more recent literature articles that have been published. This clip is based on the lit article by Deutsch and Musikant, titled: Morphological measurements of anatomic landmarks in human maxillary and mandibular molar pulp chambers. If you google those exact words, you should be able to find a pdf of the article somewhere on the internet (other than the abstract). Essentially, these gentlemen concluded that from the cusp tip to the pulp chamber ceiling is 6.0,,, distance from the pulpal floor to the furcation is 3mm, and the average height of the pulp chamber is 1.5-2mm. The pulp chamber ceiling is found at the level of the CEJ 97 and 98% of the time. Remember - this doesn't mean that this will be true for all teeth. This can be especially helpful with less of tactile perception due to calcifications. Thanks also to Dr. Hargreaves for the tip provided to us during his lecture.
