Studies on the treatment of enamel lesion by the remineralization using by laser

本研究旨在研究定量光诱导荧光法定量测定恒牙人工表面病变的平均荧光损失(ΔF)、病变面积(ΔA)和矿物质丢失(ΔQ)的重复性，并观察酸性磷酸盐氟化物(APF)再矿化液浸泡10天后，经与未经激光照射的恒牙ΔF、ΔA和ΔQ的变化。10个样品的标准偏差(ΔF、ΔA和ΔQ)的变异系数较小，分别为3.2%、1.9%和2.8%，结果重现性好。当用APF溶胶处理牙齿时。在再矿化液中浸泡10天，观察到牙釉质表面病变的再矿化进展缓慢。在应用APF后进行激光照射的情况下，在最初的2d内发生快速脱矿后，从2d开始逐渐再矿化，并持续到10d。

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.
