Advancement and role of electronic apex locators

Abstract

The electronic apex locators are the devices that are used in measuring the working length of canal which is very much needed for root canal treatment in the practice of endodontics. Apart from this, they also play important role for other conditions of tooth. They have passed through the evolution from 1st generation to 6th generation with their own merits and demerits. These devices are very much needed before starting the treatment the root canal treatment in the practice of endodontics and reduce the requirement of taking multiple radiographs for the same. Though they can’t replace radiograph for the purpose measuring working length with much accuracy but of course they do support to a great extent for the same.
