摘　　要：目的：研究人活体前牙色度学分布。方法：采用数码照像计算机色度分析系统采集、分析132例受试者上前牙色度值及Vita比色板各色片的色度值。结果：正常人前牙色度值范围为L^＊ 62．64-81．24、a^＊ 4．67-11．74、b^＊ 14．45～24．09，上中切牙亮度值（L^＊值）最大，侧切牙次之，尖牙亮度值最小，上中切牙彩度值（a^＊和b^＊值）最小，侧切牙次之，尖牙彩度值最大，Vita比色板的色度值范围为L^＊ 62．09-73．41、a^＊ 0.67～2．74、b^＊ 8．09～18．08。结论：正常人前牙色度分布具有规律性，Vita比色板的色度值范围与正常人前牙色度值范围不匹配。AIM： To study the color of human maxillary anterior teeth in vivo. METHODS： One hundred and thirty- two subjects were included. Color analysis system of digital camera and computer were used to measure L^＊ , a^＊ and b^＊ values of the tooth and Vita colormeter plate. RESULTS ： L^＊ values of tooth were 62.64 - 81.24, a^＊ values were 4.67 - 11.74 and b^＊ values were 14.45 - 24.09. L^＊ values of maxillary central incisor were the highest, L^＊ values of maxillary lateral incisor were were slightly lower, and L^＊ values of maxillary cuspid were the lowest, but a^＊ and b^＊ values of maxillary central incisor were the lowest, a^＊ and b^＊ values of maxillary lateral incisor were slightly higher, and a^＊ and b^＊ values of maxillary cuspid were the highest. L^＊ values of Vita colormeter plate were 62.09 - 73.41, a^＊ values were 0.67 -2.74 and b^＊ values were 8.09 - 18.08. CONCLUSION： The color distributing of human maxillary incisor in vivo has a rule.
