Dental apex locator is a precision dental device that is calculated the distance from the tip of the file to the foramen. The device helps to measure the distance by calculating the changes in impedance between two electrodes. Apex locator is equipped with precision components and parts, which make it a reliable and long-lasting device. Dental apex locator is widely used in dentistry. Our patrons can approach us to offer the apex locator at a cost-effective price.

The apex Locator is an electronic device for measuring the length of the root canal. Currently, the fourth-generation product is commonly used clinically to calculate WL for the ratio of resistance of various AC signals in the root canal. The principle is based on the constant resistance value of 6.5K ω between the oral mucosa and the apical orifice

The accuracy of the instrument was mainly affected by the size of apical orifice, the degree of dryness and humidity in the root canal, the root canal washing solution (normal saline, sodium hypochlorite solution), the shape and size of the guide file and the suitability of the diameter of apical orifice, the electrical conductivity of the medullary cavity and so on. For example, sodium hypochlorite solution is a highly conductive liquid, which makes the measured working length less than the actual working length.
