Teaching Model for Electronic Apex Locators
The determination of working length in one of the most important steps in root canal treatment. Failure in determining the correct working length increases the failure probability of RCT. The anatomic apical constriction is located approximately 0.5-1 mm short of major foramen and this makes it difficult to accurately localize the foramen and constriction radiographically. Electronic apex locators are a boon in locating anatomic apex. However it requires intensive practical exercises, before performing endodontic procedures on patients for the first time. The major challenge is to simulate a condition that helps students to transfer their knowledge acquired from pre-clinical labs to the clinical setups. The aim of this study is to develop an accurate, reliable endodontic teaching model which enables the use of EAIs to allow accurate evaluation of endodontic working length.
