What is an apex locator used for?
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 apex locator resistance?
1st generation Apex locators: These are also known as Resistance Apex locators. This measures the opposition to flow of direct current i.e resistance. It is based on the principle that resistance offered by periodontal ligament and oral mucous membrane is the same i.e. 6.5 K ohms.

How accurate is apex locator?
Figure 4
| Apex locators | Constriction | |
|---|---|---|
| ±0.1 mm | ±0.5 mm | |
| Mini Apex Locator® | 49% (38–59%) | 98% (92–99%) |
| ProPex® II | 49% (38–59%) | 95% (88–98%) |
| Prototype (VDW) | 38% (29–49%) | 90% (82–95%) |
How do apex locators work?
Essentially, electronic apex locators work by using the body to complete an electrical circuit. One side of the apex locator is connected to the oral mucosa (via a lip clip) and the other side to the file.
Does apex locator hurt?
Conclusions: There is no difference in postoperative pain between working length measurement methods by using an electronic apex locator or digital radiography.
Who invented apex locator?
Current history would have you believe that the evolution and development of the electronic apex locator for use during root canal procedures emanated from the work of Suzuki in 1942, which was developed as a product by Sunada in 1962.
Which size of file is the best with an apex locator?
size 15 K-
Based on this result, it can be suggested that size 15 K-file is a more suitable size for determining working length using Raypex 5 apex locator. The range of ± 0.5 mm to the foramen has been considered as the strictest acceptable range. Thus, measurements attained within this tolerance are considered highly accurate.
Is apex locator useful?
Apex locators are easy to use, speed up treatment time and can also be used repeatedly without exposure to radiation. They make root canal treatment more predictable and are an important part of the endodontic armamentarium.
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%]).
