Make sure that you are getting your initial reading by taking your file a little long to read the PDL, then back up your file short of working length, then re-advance it to your zero zero. This will “calibrate” your apex locator and will give you a more accurate reading.Mar 8, 2018

How accurate is apex locator?
What is the use of apex locator?
An electronic apex locator is an electronic device used in endodontics determine the position of the apical constriction and thus determine the length of the root canal space.
What is an advantage of using an electronic apex locator?
According to the endodontic literature, using an electronic apex locator is more accurate than radiographs in determining the location of the apical constriction.Jul 14, 2014
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%]).Dec 23, 2014
How does the apex locator work?
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 working length (WL) is the length from a coronal reference point to the apical limit of the preparation. The optimal end point for root canal preparation and obturation is to the apical constriction. This in theory would create the smallest wound.Jan 5, 2021
