Abstract
INTRODUCTION
Making use of 3D printed teeth models in teaching students offers an innovative approach. The mistakes made by the students at the access cavity stage were assessed with the aid of 3D models, and their overall, hands-on learning progress was evaluated.
MATERIAL AND METHODS
Ninety 3D models of teeth were constructed using stereolithographic technology and then randomly divided into 9 groups. One dentistry student was randomly assigned to each group and then performed primary access cavity in 10 identical 3D models. Then the teeth were evaluated in the order of their preparation, relative to the model tooth.
RESULTS
The material of 14 (15.5%) out of 90 teeth models sustained significant damage during the preparation. As regards the remaining 76 (84.5%) 3D models, the students committed the greatest number of mistakes on the incisors, and fewer on the molars and the least in the premolars. The difference in the number of errors between particular groups of teeth was statistically significant (P = .0001). The number of errors committed in subsequent repetitions amongst all students was significantly different for the incisors (P = .00215) and premolars (P = .00383), whereas insignificant in the case of molars (P = .77116).
CONCLUSIONS
Thanks to perfect representation of teeth anatomy; making use of 3D models in the teaching of endodontics may well be recommended as holding substantial potential in improving overall quality of training at the pre-clinical stage, with a view to appreciably reducing overall risk of encountering complications during the actual clinical work.
