Abstract

Our dental school allocates time to endodontic practicals to 4^th-year students who have completed the 3^rd-year course in endodontics. In this term, students practice access opening on extracted upper human single root premolars. All of the teeth were donated by students and the effectiveness of this approach for teaching was analyzed. Although all students were able to find the canal orifices of teeth with one root canal orifice, they could correctly find both orifices in 84.6% of teeth with two root canal orifices. Perforation occurred in 9.3% of the upper premolars. Knowledge of tooth anatomy is essential for students studying endodontic practice. Future efforts should be directed at improving endodontic education to ensure that failure does not occur in practice.
