Medición electrónica de la longitud de trabajo en forámenes inmaduros simulados. Un estudio ex vivo.

Abstract

Introduction: The precise determination of an endodontic treatment is to achieve a certain disinfection, cleaning and filling of the root canal system. For this, the most accurate location of the working length is needed to avoid over-instrumentation. Several experimental studies have reported that one of the most reliable results for the determination of LT (working length) is the apical locator demonstrating an accuracy of approximately 94% Objective: To evaluate its accuracy, effectiveness and efficiency by electronically measuring the working length between the groin method and the different types of apical locators. Materials and Methods: An experimental ex vivo study was conducted. 50 upper molars were used taking palatine roots into account. The sample was divided into five groups, where holes were made in the apical third resembling an open apex for the working length comparing the measurement techniques. Results: Comparison of the precision between real length, Ingle method and locators is made. APPICAL PROPEX II, PROPEX PIXI, RAYPEX VI). Obtaining 80% compared to the method of Ingle 60% and 50% in real length.Conclusion: In teeth with open apices, the tactile and electronic method offer a precise alternative to the traditional methods for determining the length of work
