摘要
目的 研究比色板颜色分布情况。 方法 选用 CIE1 976 L* a* b* 颜色系统 ,按照 JISZ872 2标准 ,采用数码相机和计算机技术 ,在标准光源下采集、测试、分析 VITA比色板各区域的色度值。 结果 比色板颈部、中部、切端部色度值不一样 ,比色板色度值范围是 :L* :6 1.0～ 86 .7,a* :- 2 .3～ 7.6 ,b* :8.3～ 2 4.7。A、B、C、D四组色片缺乏统一的规律。 结论 比色板的色度值依研究手段不同而不同。数码相机和计算机技术是牙冠色彩研究的一种新手段 ,值得进一步推广运用。
Objective\ To study the color in colormeter plate.\ Methods\ The values of color degree of the cervical,body and incisor in the VITA colormeter plate were measured with the digital-camera and computer used CIE\-\{1976\} L\+*a\+*b\+* system and JISZ8722 standard.\ Results\ The values of color degree was different in cervical,body and incisor.\ The color range of VITA colormeter plate were L\+*:61 0~86 7,a\+*:-2 3~7 6,b\+*:8 3~24 7.\ There was no same rule in A,B,C,D.\ Conclusion\ The values of color degree was different following this research methods.\ The digital-camera and computer is a new method in the field of dental color study.\;
