Background and Aim: the study of antibacterial properties of resin cements and modified glass ionomers is of great importance. The aim of this study was to determine the antibacterial effect of resin-modified glass ionomers and resin cements on cariogenic bacteria, Streptococcus mutans, Streptococcus sabrinus and Lactobacillus acidophilus. Materials and Methods:In this experimental laboratory study, samples of Streptococcus mutans, Streptococcus sabrinus and Lactobacillus acidophilus were used. 7 samples were prepared from each of glass ionomer and resin cements. After drying and sterilizing the samples, the quality control operations of the samples were performed and cultured in culture media at 37 ° C for 48 hours. According to the antimicrobial halo around each disk, its measurement the growth or non-growth of bacteria was examined. Data were analyzed using t-test and two-way ANOVA Results: The diameter of growth inhibition zone of the three studied bacteria in the presence of three materials SDI seT PP, Natural Elegance and GC Fugi Plus was significantly different (p <0.001). The diameter of GC Fugi Plus stunted halo in all three types of bacteria was larger than other groups and the stagnation halo diameter of Lactobacillus acidophilus was larger than that of Streptococcus mutans without any difference with Streptococcus sabrinus. Conclusion: The antibacterial effects of glass ionomer cement are more than the other two types of resin cements. Also, the antibacterial effects of the investigated cements on Lactobacillus acidophilus were higher than other bacteria.
