摘要：

背景：牙齿修复过程中，色彩是决定修复体是否成功的重要标志。
目的：对3种比色板在3种光源下的色度范围进行比较分析，并与中国人牙色度范围相比较。
方法：采用国际照明委员会1976L*a*b*色度系统，用数码相机及计算机色度分析系统采集、分析Vita Classial，ShoFu Vintage，Ivoclar Chromascop比色板在不同光源下的色度值。
结果与结论：Vita Classial比色板a*值偏低，并且a*，b*值范围过窄，说明Vita Classial比色板缺乏饱和度大的红色调和黄色调色片；而ShoFu Vintage比色板、Ivoclar Chromascop比色板缺少b*值较小的色片，即ShoFu Vintage比色板、Ivoclar Chromascop比色板缺饱和度较小的蓝色调片；各比色板在不同光源下的色度值也有变化，自然光、荧光灯主要差别体现在明度上，而舞台灯与自然光、荧光灯的差别体现在明度上和彩度上。

Abstract:

BACKGROUND: Color is an important sign to test whether the restoration is successful during dental repair.
OBJECTIVE: To compare the color ranges of three kinds of shade guides under three different lights, and compare these color ranges with that of Chinese teeth.
METHODS: Chroma values of Vita Classial, ShoFu Vintage and Ivoclar Chromascop shade guides under different lights were collected and measured by digital camera and computer software on International Commission on Illumination 1976L*a*b*color system.
RESULTS AND CONCLUSION: Vita Classial shade guide was lack of red and yellow shade chips with large saturation because of its low a* value and narrow a* and b* value ranges. ShoFu Vintage and Ivoclar Chromascop shade guides were lack of color chips with lower b* value which was blue shade chip with small saturation. Chroma values of each shade guide under different lights changed, the difference between natural light and fluorescent light was reflected in lightness, while the differences between stage light and natural light or fluorescent light were reflected in lightness and chroma.
