Assessment of the Antibacterial Property of Mineral Trioxide Aggregate and Glass Ionomer Cement Mixt

Mineral trioxide aggregate (MTA) is an experimental material used, as well as a root end filling material, for pulp capping. Due to its elevated mechanical strength and antibacterial function, glass ionomer cement (GIC) is a frequently used dental restorative. The aim of this study is to evaluate MTA's antibacterial property when combined with GIC. Four groups of five samples each were included in the study: Group A (MTA), Group B (GIC), Group C (MTA+GIC+MTA Liquid) and Group D (MTA+GIC+GIC Liquid). Using the Agar well diffusion method in Tryptone soya agar, all samples were screened against Enterococcus faecalis. Using the Statistical Package for Social Sciences (SPSS) for MacOS (Version 19, 2010), with the degree of significance set at P<0.05, the One-way ANOVA test was used. The average group A inhibition zone was 18.6 ± 1.714 mm, group B 0.4 ± 0.548 mm, group C 18.6 ± 2.608 mm and group D 12.8 ± 2.168 mm, respectively. The statistical significance of the data was F(3,16)=11.631, P<0.001. When combined with GIC and MTA liquid, the antibacterial activity of MTA and MTA is comparable, but stronger than that of other study groups.
