诊室内Vitapan Classical比色板的数码摄影研究

The digital study of vitapan classical shade in clinic room

目的:研究诊室内Vitapan Classical比色板各比色片中1/3部分的色度值的分布规律,以利于提高临床上的比色准确率。方法:在诊室内的光线下用数码相机对Vitapan Classical比色板进行摄影,将拍摄结果输入计算机,经Photoshop 7.0软件处理后,记录各比色片中1/3部分的亮度和R、G、B值。结果:各比色片中1/3部分的亮度和R、G、B值是不同的。结论:数码摄影能够较真实地再现诊室内Vitapan Classical比色片的颜色,可以作为临床比色方法和烤瓷材料颜色选择的补充。

Objective To improve the veracity of color-matching,we studied the middle 1/3 part of Vitapan Classical tabs in clinic room. Methods Digital photos of 16 tabs of Vitapan Classical were made under clinic room light.The RGB values of each middle 1/3 part of tab were recorded by Photoshop 7.0. Results Each middle 1/3 part of tab contains different Luminosity and RGB values. Conclusion Digital photography can reproduce the real color of Vitapan Classical tabs and be a supplement way of dental and porcelain color-matching.
