Abstract The purpose of this study was to compare the level of apical leakage between canals filled with gutta-percha/AH-Plus (GP) and the Resilon/Epiphany System (RES), when submitted to two filling techniques. Seventy extracted teeth were instrumented and randomly divided into four experimental groups in accordance with the material and techniques used [lateral condensation and Hybrid technique (HT)] and two control groups. After 7 days in an oven (37°C, 100% humidity), the teeth were immersed in India ink and cleared. Leakage was measured by the NIH imageJ program. With respect to the presence of leakage, there was no difference between the filling techniques (p > 0.05), but there was a statistically significant difference when RES was compared with GP (p < 0.05), which leaked more than RES. With RES, leakage was confined to the apical third and HT could be used to thermoplasticize RES with satisfactory results.
