Comparación in vitro de la efectividad en la obturación con el uso de dos sistemas de obturación: sistema ProFile Vortex y condensación lateral en frio, utilizando el estereoscopio

Abstract

The aim of this study was to determine the highest percentage of gutta-percha-filled area (PGFA) in the apical third of root canals after filling with cold lateral condensation technique and gutta percha carrier system, Profile Vortex Endodontic Obturators (Dentsply Tulsa Dental, Tulsa, OK). Twenty-eight extracted human single root premolars with minimum curvature based on Schneider"™s technique, were prepared with ProFile Vortex rotatory files up to apical file 35, taper 0,06, and randomly divided into two groups of 14 teeth each for both obturation techniques. The teeth were sectioned horizontally at 5 mm from the apex and observed under a stereo microscope at 40x. The total cross-sectional area of each canal was measured and the areas of guttapercha were calculated and converted to percentages of total surface area using Photoshop CS5.1. Finally, data was subjected to the non-parametric Wilcoxon test. The results show that at 5 mm, the carrier system ProFile Vortex Endodontic Obturators (Dentsply Tulsa Dental, Tulsa, OK) produced significantly higher gutta-percha filled areas (p<0,05), and as a result exhibited a more complete obturation of the root canals compared to cold lateral condensation.
