Precisão e confiabilidade de um novo localizador foraminal eletrônico – Estudo in vivo

Abstract

The determination of the actual length work is essential for successful treatment root canal. We evaluated the accuracy and in vivo reliability reading locator foraminal electronic Joypex 5 ®. We screened patients with indication for extraction for orthodontic and periodontal reasons, which resulted in a sample of 14 root canals. The teeth were radiographed in advance with the intention of detect calcifications ,punctures, and previous endodontic treatment. Performed the access cavities, the cervical and middle thirds were prepared and conducted themselves readings at the corresponding point on the display of apical foramen. After obtaining the measure file was removed and subtracted from 1mm length read digital caliper in order to then set the instrument and perform the extraction. In one sequence was performed wear on the walls at the apical region, aiming visualize the instrument tip and the continuity of apical foramen. The distance between the tip file and the actual output foraminal was measured with SEM. The average of the measurements was 0.87 mm (± 0.42 mm) The T for independent samples revealed that the data were similar (p> 0.05) between values experimental found (the tip of the instrument foramen) and tested hypothetical value of 1 mm. The study concluded that the electronic locator foraminal 5 Joypex ® proved to be accurate and reliable.
