Eficacia del localizador apical en dientes con lesiones tratados en el posgrado de la UCSG.

Abstract

Introduction: The determination of the length of the root canal using apical locators and periapical radiographs are key steps for a successful root canal treatment. However, there may be factors such as: apical lesions, dental malformations, inadequate environments, etc., that directly influence the correct functioning of the locator. Objective: to evaluate the efficacy of the apical locator in teeth with lesions treated in the postgraduate course at UCSG. Materials and methods: cross-sectional - prospective, descriptive research in which 50 patients treated at the UCSG postgraduate endodontics clinic were evaluated. The Proper Pixi apical locator (Dentsply Mailefer) was used, comparing the result of the locator with the millimetric ruler of the software used to reveal Sidexis (Dentsply) periapical radiographs in order to corroborate the length and extension of the file. Results: it was shown that the percentage of successful sockets was 84%, and the other 16% did not have an exact socket due to root injuries and moisture in the canal. Discussion: The correct handling of the apical locator in the operative field helps the professional operator to carry out a correct and successful treatment, however, factors such as root apical lesions can directly influence the failure of this length measurement.
