Eficácia de protocolos coadjuvantes (XP-ENDO FINISHER E XPENDO FINISHER R) na remoção de material obturador em raízes mesiais de molares inferiores

Abstract

The present study aims to compare the effectiveness of removing obturator material during endodontic retreatment by means of different systems. Thus, forty lower molars with mesial roots separated from distal roots, and mesial roots separated between itself. After this selection, endodontic treatment of the roots and filled with gutta percha and endodontic cement. Later it was endodontic retreatment was performed with the aid of the Reciproc system, and after completion, these teeth were randomized into two groups where each a standard a different instrument for removing the restorative material remaining: the first group was instrumented with XP-endo Finisher and the second group with XP-endo Finisher R. After all the steps have been completed, were analyzed through Computed Microtomography, the which evidenced the amount of remaining filling material, as well as the effectiveness of the formatting of the root canals with regard to transport and centralization of preparation for each group, thus comparing the results. THE percentage of gutta percha removed after the supporting step was 75% for Xp-endo Finisher and 82% for XP-endo Finisher R, with no differences between groups (p> 0.05). None of the channels were exempt from remaining material, regardless of the instrument used.
