The purpose of this study was to compare and evaluate the remineralization effect of three types of fluoride varnishes on demineralized enamel of primary teeth.
40 primary teeth were decalcified by soaking them in artificial acidic solution and stored at 37¡É for 7 days. Then 3 varnishes - Cavity shield¢â, V varnish¢â and MI varnish¢â were applied respectively one time a week, for 3 weeks on the demineralized enamel surface.
For the first week, MI varnish¢â showed the highest microhardness value, V varnish¢â was in second position, and Cavity shield¢â showed the lowest microhardness value. However, there was no significant difference among the three groups(p > 0.05).
For the second week, V varnish¢â showed the highest microhardness value, and MI varnish¢â came next in second position noting no significant difference (p > 0.05). Cavity shield¢â was significantly lower than the other groups (p < 0.05).
For the third week, V varnish¢â showed the highest microhardness value, noting a significant difference from the other groups (p < 0.05). MI varnish¢â came next, while Cavity shield¢â showed the lowest microhardness value. However, there was no significant difference between MI varnish¢â and Cavity shield¢â (p > 0.05).
The increase in the microhardness of groups V varnish¢â and MI varnish¢â were higher than that of group Cavity shield¢â (p < 0.05), while no significant difference was noted between groups V varnish¢â and MI varnish¢â (p > 0.05).
