摘　　要：目的:烤瓷牙龈比色板研制及颜色分析。方法:选用金属牙龈瓷粉G1~G5和染色剂Akz01~Akz20,按10∶1质量比混合后分组,G1与Akz01~Akz20混合标记为A组、G2与Akz01~Akz20混合标记为B组、G3与Akz01~Akz20混合标记为C组、G4与Akz01~Akz20混合标记为D组、G5与Akz01~Akz20混合标记为E组,采用Vita Easyshdy4. 0比色仪测量5组色片的L*、C*、H*值,并与牙龈色度值进行比较。结果:5组烤瓷牙龈比色板的L*值的分布范围为10. 10~26. 90、C*值的分布范围为0. 50~14. 20、H*值的分布范围为0. 80~72. 40;同天然牙龈相比较,5组定制比色板的色度值范围在天然牙龈色度值范围内(P <0. 01)。结论:定制比色板的颜色能基本模拟天然牙龈的颜色,对于临床牙龈颜色传递有一定意义。Objective：To research and analysis the gingival colorimetric plate for porcelain. Methods： Vita company products of gingival porcelain powder G1～G5 and coloring agent Akz01～Akz20 were selected and grouped according to mixed at 10 ∶1 mass ratio. The mixture of G1 and Akz01-Akz20 was recorded as Group A; G2 and Akz01-Akz20 were recorded as Group B; G3 and Akz01-Akz20 were recorded as Group C; G4 and Akz01-Akz20 were recorded as Group D; G5 and Akz01-Akz20 were recorded as Group E.Electronic weighing scales, weighing paper bag, each packet contains 21samples, Sintering on Ni-CD alloy to form a colorimetric sheet. The L＊, C＊ and H＊ values of 5 sets of color plates were measured by Vita Easyshdy 4.0 colorimeter, and gingival color values were compared. Results： The L＊ value of the porcelain gingival colorimetric plate was in the range of 10.10-26.90 ;C ＊ 0.50-14.20 and H ＊ 0.80-72.40. Compared with gingiva, the color value range of custom-made colorimetric plate of the five groups is in the range of natural gingival color （ P〈 0.01）. Conclusion： The color of the custom colorimetric plate can basically simulate the color of the natural gingiva.It has some significance for the color transfer of clinical gum.
