Abstract

The present study evaluated the antibacterial effect and inhibition ability of enamel demineralization of S-PRG composite material in a microcosm biofilm model.

The bovine tooth was sectioned and embedded in a cylindrical acryl mold. To fill the dental materials, single hole was drilled on the enamel. Each of the two restorative materials, composite resin, S-PRG composite material was filled the hole. The specimens were incubated in the basal medium mucin(BMM) as microcosm model. After 7 days, surface hardness and red/green value (red fluorescence intensity) was measured using Vickers hardness tester and QLF-D. Changes in red fluorescence and surface microhardness were analyzed using one-way ANOVA and Tukey post hoc, with a significance level of 0.05.

There was no significant difference in changes of the red fluorescence intensity among the groups according to maturation time. The mean ΔVHN was-31.6 ± 13 for the control group, -30.9 ± 5.17 for the resin group, and-15.4 ± 9.8 for the S-PRG groups. The differences between the S-PRG group and the other two groups were statistically significant (p < 0.05).

The S-PRG filler showed a significantly lower demineralization effect than the other groups. S-PRG composite material may inhibit the demineralization of enamel owing to its ion emissioncapability.
