摘要: 目的 探讨VINTAGE和UNIBOND技工标准比色板的颜色间隔,确定人眼在比色板各色号间的可辨色数 目。方法 利用分光光度仪,测量各色号的色度学参数,计算出相邻各色号间的色差值,再除以人在牙色范围内的 最小辨色能力,得到人眼在VINTAGE和UNIBOND技工标准比色板各相邻色号间能分辨的颜色数。结果 VIN- TAGE和UNIBOND技工标准比色板各相邻色号间人眼可分辨的颜色数为3~6个。B色号的颜色间隔较大,D色号 的颜色间隔较小;高明度区域的色号颜色间隔较大,低明度区域色号颜色间隔较小。结论 VINTAGE和UNIBOND 技工标准比色板各色号间存在着一定的颜色间隔,临床比色工作中不能完全依靠比色板进行牙色的表达。

Abstract:

Objective To research the color space of the standard color board, guide the clinic work of color match, and es- tablish an foundation for deeper researching.Methods Through taking analysis of reflecting spectrum and spectral tristimulus, each parameter of the color on standard boardwas found out. The color difference between border upon colors on boardwasworked out throughmatchingthe color parameters. The number of color space between each border upon color on standard color board, di- vided byΔE=1.5, was found.Results The number of color space between each border upon colorwas 3~6. The color space was bigger in group B, but smaller in group D. The color space was bigger in high lightness area, but smaller in low lightness ar- ea.Conclusion Some color space has been found between standard color borders of VINTAGE and UNIBOND. Color of natural teeth is unable to be completely included into standard color border, especially in clinical care.
