【摘要】 目的 :研究用松风 Shade- eye- EX电脑比色仪测量比色板颜色时的稳定性。方法 :用松风 Shade- eye- EX电脑比色仪测量 Vintage Halo(松风 )、VITA及 Vita 3D- master比色板的每个比色片 ,每片测量 9次 ,分别用松风 Shade- eye- EX自然牙及瓷牙测量模式测量 ,3人次每人重复完成一次。结果 :(1)瓷牙测量模式测量时 ,Shade- eye- EX对 Vita 3D- master、VITA及 Vintage Halo(松风 )比色板测量结果绝大多数表现为同一数字结果。(2 )测量比色板时 Shade- eye- EX应用瓷牙测量模式较自然牙测量模式准确率高。(3)在两种模式测量比色板下 ,同一次测量的三次按键时 ,测量头位置保持不动 ,结果显示数字的同一性较高 ;测量头位置每次都动时 ,结果显示数字变动性较大 ;(4)无论采取任何方式 ,三种比色板的结果总会有一些结果显示不同。结论 :松风 Shade- eye- EX电脑比色仪测量颜色时 ,测量模式与需测量对象相符 ,否则 ,结果会有很大的差异 ,甚至比色失败更多还原

【Abstract】 Objective :To stusy the stability of color in shade guide measured with Shade-eye-EX.Method:Each tab of shade guide of the Vintage Halo,the VITA and the Vita 3D-master nine times measured was with Shade-eye-EX, in tooth mode and in po-crown mode. Result:The same color result of the tabs of each shade guide was obtained in Vita 3D-master,VITA and Vintage Halo with Shade-eye-EX in po-crown mode. The examine which was repeated three times just before the instrument was removed gave more accurate result than that when the instrument was removed and reset each time in two modes. Conclusion : Shade-eye-EX can give the true color of shade guide .更多还原
