Purpose: The aim of this study is to assess the effect of commercially available dentifrices with different fluoride formula on remineralisation of enamel surface. Material and Methods: Enamel blocks were ground flat with water-cooled carborundum discs 320, 600 and 1200 grit and randomly divided into seven groups. The specimens were subjected to a daily cycling regime comprising two one-minute brushing treatments; one before and one after the demineralization period of 6 hours and 18 hours, and remineralisation in artificial saliva. During the pH cycling regimen each of those seven groups were treated with different dentifrices: fluoride dentifrice Sensodyne Rapid 1040 ppm NaF, Colgate Total 1100 ppm NaF, Parodontax fluoride 1400 ppm NaF, Sensodyne fluoride 1400 ppm NaF, Pronamel Sensodyne 1450 ppm NaF, Elmex-GABA International 1250 ppm F Amine fluoride, and fluoride free Detartrine Paste Septodont. The surface microhardness SMH of those specimens was determined at baseline and after 12 days using HMV-2000 50 g, 490.3 mN, 10 s Shimadzu, Japan. Results: All specimen groups treated with fluorides showed increase in SMH compared to control group. Pronamel, Sensodyne F, Sensodyne Rapid and Colgate Total were statistically superior to other fluoride dentifrices and a fluoride-free control after 12 days pH-cycling regime. Rates of enamel microhardness at baseline and after 12 days cycling treated with Parodontax obtained increase in SMH, but it was not statistically significant p>0.05. Conclusion: The results obtained in the present study show that high fluoride toothpastes 1450 ppm effectively inhibit demineralization under experimental conditions.
