摘要
目的用数码摄影方法研究ShoFu Vintage(松风)比色板各比色片中1/3区域的亮度(L)值及R、G、B值的分布规律,以期提高临床修复体的比色准确率。方法在5000K光源下用数码相机对ShoFuVintage比色板的各比色片进行摄影,将拍摄结果输入计算机,运行Photoshop7.0软件,记录各比色片中1/3区域的亮度(L)和R、G、B值。结果比色片的亮度(L)值及R、G、B值的分布与其A、B、C、D系列的分类有关。同系列比色片中随标号序数的增加,亮度(L)值及G、B值反而降低。R值分布表现为各系列中间序号的比色片较高。结论数码摄影能够比较真实地再现ShoFuVintage(松风)比色板的颜色,可作为临床修复体比色方法的补充。
Objective To improve the dental clinic veracity of colour-matching, we studied the distribution rule of the L and R.G,B value of the middle 1/3 of ShoFu Vintage tabs with digital photography. Methods Digital photos of 19 tabs of ShoFu Vintage under 5000K fluorescent light were taken and inputted into computer. Photoshop 7.0 was run and the RGB values of each middle 1/3 tab were recorded with Photoshop 7.0. Results The distribution of the L and R.G,B values of each tab were related with A,B,C .D classifications. In the same classification, the L and R,G.B values of each tab decreased while the label number increased, and R values of the middle label number were higher than others＇. Conclusion Digital photography can reproduce the real color of ShoFu Vintage tabs and be a supplement way of dental clinic color-matching.
