Abstract
The objective of this in vitro study was to monitor the amount of remineralization of decalcified enamel according to the number of fluoride varnish application using quantitative light-induced fluorescence-D and polarizing microscope. Artificial white lesion induced on the sound 72 teeth, CavityShieldTM (Group I), FluroDoseTM (Group II) and Flor-Opal® Varnish (Group III) were applied 1, 2 or 3 times every two weeks. The following results was obtained: 1. In group I, II and III, ΔL were increased. From regression analysis of ΔL by the number of application, the equation was y = 3.878x + 90.612 in group I, y = 3.133x + 37.168 in group II, and y = 3.509x + 82.322 in group III(p < 0.05). 2. In group I, II and III, ΔD were decreased. From regression analysis of ΔD by the number of application, the equation was y = -2.336x + 107.235 in group I, y = -2.158x + 101.620 in group II, and y = -1.940x + 94.806 in group III(p < 0.05).3. The Pearson correlation value between the ΔL and ΔD was -0.673 in group I, -0.574 in group II, and -0.431 in group III(p < 0.05).
