Effect of the Fluoride Varnishes Comparing to CPP-ACP Complex on Human Enamel Demineralization/Remineralization

Aim: This in vitro study was conducted to investigate the effect of fluoride varnishes comparing to CPP-ACP complex on the inhibition of enamel demineralization. Materials and methods: Enamel blocks were ground flat, allocated into five groups and subjected to a daily cycling regime. Three groups were treated within the period of 10 min with fluoride varnishes: Fluoridin N5, Bifluorid 12 and Fluor Protector, one was treated only with GC Tooth Mousse (Recaldent CPP-ACP 10.0%)and one control group. Fluoride varnishes were coated once a week before the demineralization period. All specimens were stored in artificial saliva between and after cycles. The surface microhardness (SMH) of the specimens was determined at baseline and after 12 days using HMV-2000 (Shimadzu, Japan). The percentage of SMH change (%SMC) was calculated before and after cycling regime. Data were analysed by t-test for individual comparisons (p < 0.05). Results: Statistical analysis by t-test showed significant difference between SMH before and after fluoride treatment in all groups. All groups treated with fluoride varnishes and GC Tooth Mousse showed increase in SMH. The highest values of increase in SMH were observed for the Fluoridin N5. There was no significant statistical difference between the %SMH of the enamel between groups. Conclusion: The results obtained in the present study showed that high fluoride varnishes and Tooth Mousse effectively inhibit demineralization under experimental conditions.
