Abstract
The purpose of this study was to evaluate the effect of fluoride varnish on prevention of enamel demineralization. Eighty bovine enamel blocks were divided randomly into 4 groups of 20 specimens: Group I served as the control with no topical application of fluoride. Group II was treated with APF gel for 4 minutes. Group III was treated with Fluor Protector. Group IV was treated with CavityShield. After 24 hours of treatment, samples were brushed with a soft bristled tooth brush to stimulate normal mechanical wear of varnish. Early caries lesions were produced by placing each specimen into demineralization solution at pH 4.0 for 48 hours. Then the optical density of the lesions were measured by light fluorescence induced by plasma light and the surface microhardness were measured by the vicker's hardness test.
The results were as follows:
1. The optical density of group III, IV were significantly higher than that of group II, but no significant difference was noted between group III and IV.
2. The surface microhardness of group IV was the highest, followed by group III, II, and I(p<0.05).
3. There were no significant differences between group III and IV in optical density. However, the surface microhardness of group IV was significantly higher than that of group III.
The results of present study indicate that the fluoride varnish is more effective than APF gel for prevention of dental caries.
