项目摘要

The conventional method of teeth whitening, office bleaching, uses high concentrations of hydrogen peroxide. The objective of this study was Application for the vital bleaching of HClO solution. Both pH 6.5 Campher^<TM> were examined Effective chlorine density and biocompatibility. The grouth of oral epithelial cells and fibroblast cells were not affected by Campher^<TM>. Campher^<TM> with HAP residual chlorine density was not found a decrease. It was suggested that clinical application was possible by perception Campher^<TM> was safer and adding HAP as a result of these. Dentin and Enamel treated by Campher^<TM> and 35%H2O2 for 1 hour. Microhardness was measured at surface. A decrease in microhardness was found at dentin treated by both agent and enamel treated by 35%H_2O_2. Perception Campher^<TM> decreased hardness of the dentin surface, but it was suggested was not found a decrease on the enamel. As for perception Campher^<TM>, the adaptation to the walking bleach method is not appropriate than this and bleaching materials suitable for vital bleaching. In addition, a bleaching effect was accepted for the stained surface about the bleaching effect, but, as for the bleaching effect for the tooth discolouration, an effect was not accepted. The bleaching experiment using the fresh withdrawal tooth was not made have difficulty in acquisition this time. The experiment by the human fresh extracted tooth is necessary.

牙齿美白，办公漂白的常规方法使用高浓度的过氧化氢。这项研究的目的是应用HCLO溶液的重要漂白。两种pH 6.5 Campher^<tm>均已检查有效的氯密度和生物相容性。口服上皮细胞和成纤维细胞的gro氏不受Campher^<tm>的影响。没有发现具有HAP残留氯密度的Campher^<tm>降低了。有人认为，通过感知campher^<tm>可以使用临床应用，因此增加了HAP。 Campher^<TM>和35％H2O2处理1小时的牙本质和搪瓷。在表面测量了微硬度。在牙本质和牙釉质治疗35％H_2O_2治疗的牙本质上发现了微硬度的降低。感知凸轮^<tm>牙本质表面的硬度降低，但建议没有发现牙釉质减少。至于感知Campher^<tm>，对步行漂白方法的适应不适合此，并且是适合重要漂白的漂白材料。此外，关于漂白效果的染色表面也接受了漂白效果，但是，对于牙齿变性的漂白效果，不接受效果。这次没有使用新鲜戒断牙齿的漂白实验难以获取。人类新鲜提取的牙齿是必要的。
