Teaching model for artificial teeth and endodontic apex locators

Artificial teeth are a useful teaching aid during endodontic education. This article describes the development of a simple and inexpensive model that can be equipped with artificial teeth. It shows that working length determination in artificial root canals using electronic apex locators is possible and that the embedding media has no influence on measurements. The model supports the application of current endodontic techniques and facilitates a validated evaluation of the treatments between students. Artificial teeth can be removed for visualization and replaced for further endodontic exercises.
