Research on Vital Bleach TechniquesThe purpose or this study was to determine the bleaching efficacy with different light sources on artificially discolored bovine teeth. Extracted bovine mandibular anterior teeth were soaked in a Fuchsine Basic 0.5% solution for 3days to prepare artificially discolored teeth. Three chairside bleaching agents, Apollo Secret In-Office whitening (DMD, CA., USA), Hi-Lite (Shofu, Kyoto, JAPAN) and Quasar Brite (Inter Dent, CA., USA) were employed and two types or light unit, Wite-Lite (300mW/cmィイD12ィエD1, with halogen lamp) and Plasma Arc Curing: PAC (1400mW/cmィイD12ィエD1, with xenon lamp) were used. After baseline color measurement with a calorimeter, these teeth were divided into 5 groups. Group or Apollo Secret were irradiated with PAC for 30sec, Hi-Lite groups with PAC 30sec, or with White-Lite 60sec and l80sec and Quasar Brite with PAC for 30sec. The bleaching procedure were repeated 3 times. We also measured pH change or bleaching paste during irradiation and bleached surfaces were observed by SEM.Hi-Lite had low pH value of 3.9 to 4.2, Apollo Secret and Quasar Brite has 7.2 to 8.0. No morphological difference was recognized by SEM observation before and after bleaching. Bleaching effect was determined by calculating delta E value (CIELab color system).The highest color difference was achieved Quasar Brite with PAC 30sec. ANOVA revealed that Hi-Lite with PAC 30sec had significantly higher value comparing Hi-Lite with Wite-Lite 180sec. Apollo Secret with PAC30sec and Hi-Lite with Wite-Litel80sec had no significant difference.

关于重要的漂白技术或本研究的研究是为了确定人为变色的牛牙的不同光源的漂白效率。将提取的牛下颌骨前牙浸入紫红色的基本0.5％溶液中，用于3天，以准备人为变色的牙齿。 Three chairside bleaching agents, Apollo Secret In-Office whitening (DMD, CA., USA), Hi-Lite (Shofu, Kyoto, JAPAN) and Quasar Brite (Inter Dent, CA., USA) were employed and two types or light unit, Wite-Lite (300mW/cmII D12E D1, with halogen lamp) and Plasma Arc Curing: PAC (1400mW/cmII使用D12E D1，带有Xenon灯）。用量热计测量基线颜色后，将这些牙齿分为5组。将30秒的PAC，HI-Lite组辐射为PAC 30sec，或与PAC 60sec和Quasar Brite一起使用PAC的组或Apollo Secret，供PAC进行30秒。重复3次漂白过程。我们还测量了辐照过程中的pH变化或漂白糊状，并通过SEM观察到漂白的表面。Hi-lite较低的pH值为3.9至4.2，Apollo Secret和Quasar Brite和Quasar Brite的pH值为7.2至8.0。在漂白之前和之后，SEM观察结果没有识别形态学差异。通过计算delta e值（Cielab颜色系统）来确定漂白效果。用PAC 30sec实现了最高的颜色差异。 ANOVA显示，与Wite-Lite 180sec相比，PAC 30sec的Hi-Lite具有更高的值。带有PAC30SEC的Apollo Secret和Wite-Lite80sec的Hi-Lite没有显着差异。
