两种常用比色板的临床色度学研究

目的从临床角度探讨两种比色板色度学的变化。方法用Shade Eye EX电脑比色仪分别测试Shofu16色比色板和Vita16色比色板的比色片，获得比色片的色调、彩度、明度、色相和瓷粉配方。结果两组比色片的B色调全测为A系列，大多数比色片的色相测为R系列；多数Vita比色片的彩度高于Shofu比色片；两组比色片的明度排列次序不符合Vita 16色比色板的明度排列次序指示，Shofu比色片的明度普遍高于Vita比色片；绝大多数比色片的颜色复制需用偏红色调瓷粉，或需添加偏红色调及红色瓷粉。结论用Shofu 16色比色板或Vita 16色比色板比值和配色，需添加其他系列或特殊颜色的瓷粉。

Clinical Study on Chromatometry of Two Shade Guides

Objective To study the clinical application on chromatometry of two shade guides.Methods Each shade tab of Shofu Vitage-Unibond shade guide and Vita classical shade guide was measured with Shade Eye-EX.Results Most incorrect shade matchs were existed in B shades of two shade guides.The color of many shade tabs of two shade guides tended to be red hue.Value arrangement of two shade guides measured dosen't match that of Vita classical shade guide. Conclusion To match color of these shade tabs of two shade guides,other shade porcelain powders were chosen and the specical color porcelain powders should be added.
