Comparação entre dois localizadores foraminais eletrônicos na determinação da odontometria: estudo in vitro.

Abstract

In the last years, positive technological advances have been noted in relation to electronic apex locators. It is known that conventional radiographic methods can be used to define the working length during endodontic treatment, however, electronic foraminal locators have proved to be very effective and reliable, helping the dental surgeon, optimizing the work and performing a more precise odontometry. The high cost of these locators justifies their use not being so widespread. This study aims to compare two brands of electronic foraminal locators, identifying the accuracy of each one of them and establishing, according to the results, a definition of which device has greater precision and reliability among those studied. For the study we will use 20 extracted teeth and two equipments: Propex Pixi™ manufactured by Dentsply Indústria e Comércio LTDA; and Sensory manufactured by Schuster Comércio de Equipamentos Odontológicas LTDA. These electronic devices have the function of finding the apical foramen based on the difference in the tissues found inside the root canal. During the performance of odontometry on the teeth under analysis, they will be annotated with the contribution of the excel program (Microsoft, USA) and later the methods of execution will be evaluated and compared to obtain the results. It is expected that with the conclusion of this applied work, the best tool for performing odontometry in endodontic treatments will be established. It is also expected that the most accurate and reliable instrument among the devices used during the performance of the work will be defined.
