| Research Abstract |
This study is to examined the reproducibility of Quantitative Light-induced Fluorescence to quantify an average fluorescence loss (ΔF), lesion area (ΔA) and mineral loss (ΔQ) in an artificial surface lesion on permanent teeth and to investigate the ΔF, ΔA and ΔQ of each tooth with and without Nd: YAG laser irradiation after acid phosphate fluoride (APF) application during immersion into a remineralization solution for 10 days. The coefficients of variance of standard deviation (ΔF, ΔA and ΔQ) for 10 indicated that were relatively small, 3.2%, 1.9% and 2.8% respectively, and the results good reproducibility was obtained. When the teeth treated with APF sol. were soaked in the remineralization solution for 10 days, it was observed that remineralization of the lesion in the enamel surface was advancing slowly. In the case of Nd: YAG laser irradiation after APF application, gradually remineralization proceeded from 2^<nd> day starting for 10 days after rapid demineralization occurred within the initial 2 days.
