Comparison of the sealing ability of Endocem mineral trioxide aggregate and Endoseal mineral trioxide aggregate as a furcal perforation repair material under the operating microscope: An in-vitro study

Abstract

Objective: The aim of this study was to compare the sealing ability of pozzolan-based mineral trioxide aggregate (MTA) (Endocem) cement and pozzolan-based MTA (Endoseal) when used to repair the furcal perforations in permanent molars using the stereomicroscope. Materials and Methods: The study sample comprised forty-three recently extracted permanent molars. These teeth were placed in a 5.25% sodium hypochlorite solution for 24 h and washed with tap water. Access cavities were made using a #5 round bur in high-speed handpiece. Perforations were made in the center of the floor of the pulpal chamber using a round bur. The teeth were randomly assigned into three experimental groups based on the material used to seal the perforation: Group 1 - control group, Group 2 - Endocem MTA group, and Group 3 - Endoseal MTA group. The packed materials were allowed to set for 24 h. The samples were sectioned longitudinally, and the extent of marginal adaptation was measured by stereomicroscope. Kruskal-Wallis test was used for statistical analysis using SPSS software. Results: The difference in the mean length of dye penetration between groups was statistically significant. The pair-wise comparison was done between the three groups using Mann-Whitney U-tests as post hoc analysis, which reveals the difference between Group 1 and Group 2 was statistically significant P < 0.04 and also between Group 2 and Group 3 P < 0.001. However, the mean difference between Group 1 and Group 3 was non significant P < 0.31. Conclusion: Endoseal MTA showed more microleakage than Endocem MTA. Therefore, within the limitations of this study, we suggest that Endocem has the potential to be used as a perforation repair material rather than Endoseal MTA.
