Despite the excellence properties of mineral trioxide aggregate sealer (MTAS), it may have some influence in its sealing ability. The purpose of this study was to analyze and compare sealing ability of MTAS and resin epoxy sealer (RES). Thirty-two extracted human lower premolar teeth had their canals prepared with ProTaper Universal. This group divided into two groups, group 1, the root canals were filled using guttaperca with MTAS and Group 2 root canals were filled using guttaperca with RES. All samples were incubated at the temperature of 370C for 24 hours with 100% humidity. Then the whole sample were immersed in India ink for 7 days. Samples were washed and decalcified until became transparent. The penetration of India ink was evaluated by using a stereo microscope, and the scores are were given by criteria: score 1: 0-0.5 mm ink penetration; a score 2: ink penetration 0.51- 1mm; and a score 3: ink penetration > 1 mm. Score 1 in the group RES 37.5%, and 21.9% MTAS group, score 2: RES (3.1%) and MTAS (12.5%), score 3: RES 9,4% and MTAS 15,6%. The data was analyzed using ANOVA SPSS 17 at 5% significance level. Statistical analysis between the two groups showed no significant difference. As a conclusions the sealing ability of MTAS showed the same level with RES.
