摘　　要：目的测定分析试色糊剂与相应颜色的树脂粘结剂间颜色的一致性和差异。为全瓷修复时应用此种材料提供经验和依据。方法应用光电比色仪及ＣＩＥＬａｂ色度系统，对Ｖａｒｉｏｌｉｎｋ三种颜色的试色糊剂与相应颜色的树脂粘结剂进行颜色测量和分析。结果２００号试色糊剂与相应的化学固化树脂的颜色相比，△Ｅ＜１．４。其余树脂粘结剂与相应的试色糊剂相比较，△Ｅ值均大于３３。结论２００号试色糊剂与化学固化树脂粘结剂的颜色一致性最好，但试色糊剂较光固化树脂粘结剂略亮、略黄。与试色糊剂相比，１００号树脂粘结剂略暗、略黄，３００号树脂粘结剂略亮、略黄，颜色均有明显差异。Objective This study was to measure the color coincidence and difference of resin cement and its try in paste.Methods 3 shades of a resin cement and its try in paste were measured and analyzed by CIE L  a  b  on a reflection spectrophotometer.Results For shade 200, vulue of △E  was less 1.4 in comparison between try in paste and self cured resin.Conclusion The try in paste of shade 200 matched the self cured resin cement very well, but the try in paste was lighter and more yellow than the light cured resin cement. The resin cement of shade 100 was darker and more yellow than try in paste; resin cement of shade 300 was lighter and more yellow than try in paste.
