Apex Locator Dental by Scantrik

Features:

• Electronic device
• An apex locator is a device that uses electronic circuitry to determine the position of the apical foramen and the length of a root canal space. 
• Impedance-based
• Some apex locators use impedance to work, which is based on the idea that the walls of a root canal have electrical impedance due to the presence of dentin. 
• Accurate
• Apex locators can be reliable and accurate in determining working length. For example, one study found that using an apex locator to measure the apical constriction was more accurate than radiographs. 
• Displays file progress
• When an apex locator is used, a series of bars on the display show the file's progress as it moves through the root canal. 
• Audible warning
• Some apex locators have an audible warning with volume control. 
• Self-test
• Some apex locators have a built-in self-test to quickly check their function. 
• Some early apex locators had poor accuracy in the presence of fluids and pulp tissue, and needed to be calibrated.
