This study was to measure the color coincidence and difference of resin cement and its try-in paste.
3 shades of a resin cement and its try-in paste were measured and analyzed by CIE Lab* on a reflection spectrophotometer.
For shade 200, vulue of delta E* was less 1.4 in comparison between try-in paste and self-cured resin.
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.
本研究旨在测量树脂水门汀及其试戴糊剂的颜色一致性和差异。
在反射分光光度计上，采用CIE Lab*对3种色度的树脂水门汀及其试戴糊剂进行测量和分析。
对于200号色度，试戴糊剂与自凝树脂之间的ΔE*值小于1.4。
200号色度的试戴糊剂与自凝树脂水门汀匹配良好，但试戴糊剂比光固化树脂水门汀颜色更浅且更偏黄。100号色度的树脂水门汀比试戴糊剂颜色更深且更偏黄；300号色度的树脂水门汀比试戴糊剂颜色更浅且更偏黄。
