摘　　要：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Shofu 16色比色板和Vita 16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色比色板比色和配色,需添加其它系列或特殊颜色的瓷粉。Objective To study the clinical application on chromatometry of two shade guides.
