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.
