Uso de localizadores apicais eletrônicos na terapia endodôntica: uma revisão de literatura

Abstract

INTRODUCTION: Working length is the standard measurement used for endodontic instrumentation. For endodontic treatment to be successful, this measurement needs to be achieved as precisely as possible. In an attempt to achieve this purpose, studies have associated the use of electronic apex locators. OBJECTIVE: To carry out a survey, through a literature review, about the effectiveness of electronic apex locators in determining the real working length during endodontic treatment. MATERIALS AND METHODS: A selection of files published on the Pubmed platform was carried out, taking into account the period from 1986 to 2023, in order to analyze a more comprehensive number of articles. RESULT: It was noted that electronic apex locators are an effective alternative to determine the working length during endodontic treatment compared to apical radiographs and the use of cone beam computed tomography. Furthermore, they are an excellent tool for detecting perforated root canals, however, they have limitations in cases where a glass fiber or post is present in the region, creating an obstacle to diagnostic accuracy. CONCLUSION: The choice to use the electronic apex locator is an advantageous alternative for the success of endodontic treatment, mainly due to its accuracy in determining the working length for endodontic therapy with a better prognosis for the patient.
