Electronic apex locators use an electrical circuit through the patient's root canal and oral tissues to determine the location of the apical foramen. ... The electrical circuit is completed when the instrument is inserted into the root canal in the apical direction and touches the periodontal tissues.Aug 21, 2018
How does apex locator measure work length?
The best working length is found by subtracting approximately 0.5 mm from the length obtained with the apex locator. It is important to know that there is potential for interference of an electronic apex locator with a patient's cardiac pacemaker function.
Is apex locator accurate?
Although in the ranges 0.1 and ±0.25 mm the ApexPointer had the highest accuracy, the rank analysis showed that 39% of the measurements were beyond the foramen (Figs 4 and 6). There were no significant differences between the various types of teeth and root canals.Jul 4, 2017
Can apex locator detect perforation?
The Apex NRG and RayPex 5 also detected all perforations (100% sensitivity; 95% confidence interval [78%; 100%]). The ProPex II, Elements Apex Locator, and RayPex 6 detected 14 of 15 perforations (93% sensitivity; 95% confidence interval [68%;100%]).Dec 23, 2014
What is Endo motor in dental?
The endodontic motors are devices designed to facilitate the endodontic process, since they allow the use of mechanically driven files. This allows the endodontist a greater speed and convenience in the preparation of the endodontic canals.Feb 12, 2019

How do I choose an endo motor?
A much more preferable parameter would be the use of a specific ideal (right) torque. So choose an endomotor that offers great flexibility when it comes to speed and torque settings, as different files systems have different ideal torque values. So, before you buy an endomotor, do look for the speed and torque control.Jul 26, 2017
What is an endo procedure?
Endodontic procedures include every treatment involving the inner tissues of the teeth, otherwise known as the pulp or nerve. The word “endodontic” is derived from two stems: “endo,” meaning inside, and “odont,” meaning tooth.
