Summary
Various methods have been used in the history of endodontics, to determine the length of the root canals (working length), such as tactile sensation and X-rays. Recently, apical locators have acquired importance, due to their precision. The use of Cone Beam has now also been incorporated. Because there are many ways to measure this length, it is necessary to test them and see if they resemble the standard gold measurement technique defined in the literature as the electronic apex locators. The purpose of this research is to determine whether there are statistically significant differences in the working length between the electronic apex locators, and the use of Cone Beam processed with the Software 3D Endo by Dentsply Sirona. For this, 30 extracted pre-molars were selected, for Cone Beam tomography and 3D endo Software analysis, to measure the working length. Once this was carried out, cavity preparation was performed manually, and the cervical third approached with gates glidden drills 1 and 2. Subsequently, the teeth were placed in a Pro Train model, which resembled the properties of the teeth in the oral cavity, to allow the use of the electronic apex locators to determine the working length.Once the data were obtained, they were compared through the proportions Test (p = 0.05 hypothetical), resulting in p = 0.2, indicating that there are no statistically significant differences in the working length between the two methods.
KEY WORDS: software, 3D endo, working length, preoperative, endodontic treatment.
