Abstract：AIM: To examine the effect of a fluoride varnish product on the remineralization of bovine enamel using Quantitative Light-induced Fluorescence (QLF) in vitro. MEHTODS: Twenty extracted bovine anterior teeth were used in this study. On the labial surface of each tooth, 4 artificial subsurface lesion windows (2 mm ×2 mm) were created by immersion in demineralizing solution. The windows were randomly divided into 4 groups (n =20/group) and were treated with fluoride varnish, a commercially available toothpaste containing 900 ppm F~-, 1% sodium fluoride solution and deionized water, respectively. The average fluorescence loss F (%) and lesion size (mm~2) were determined with QLF at the 4th, 8th, 16th and 32nd day after treatments. Another variable, delta Q, which was defined as the fluorescence loss integrated over the lesion size (%, mm~2),was calculated. RESULTS: The results showed that the fluoride varnish significantly (P < 0.05) increased the remineralization size and reduced delta Q values as compared with the other 3 groups. CONCLUSION: These findings suggested that fluoride varnish might be useful to enhance the remineralization in vivo.
