comparative study of antimicrobial efficacy of glass ionomer cement and reinforced zinc oxide eugenol cement on causative microorganisms of early childhood caries: an in vitro study

ABSTRACT

The aim of the present study was to compare antimicrobial efficacy of Glass Ionomer Cement GIC and Reinforced Zinc Oxide Eugenol Cement ZOE; IRM on Strepeptococcus mutanas, lactobacillus and veillonella which is the causative microorganisms of early childhood caries. A marked bacterial inhibition of streptococcus mutans, lactobacillus and veillonella were detected after one and three days for both materials. At the same time, it was clear that the inhibition effect of GIC and ZOE were increasing with time. Moreover, GIC showed a higher percentage of bacterial inhibition. From the results of our study, it could be concluded that both Glass ionomer cement and zinc oxide eugenol cement had marked inhibitory effect on streptococcus mutans, lactobacillus and veillonella which believed to be the causative microorganisms of early childhood caries [ECC]
