摘要
目的 比较相同颜色标号的光敏树脂的色度学特性。方法 以 9个公司颜色标号为A2、A3、A 3.5、B2、B3、C2、C3的光敏树脂为实验对象 ,经测色后比较相同颜色标号的光敏树脂组内任意两种光敏树脂之间颜色 3种属性的差异 ,并计算出同一组内任意两种之间的色差 (ΔE ab)的平均值。结果 不同公司颜色标号相同的光敏树脂的色度学指标有明显差异 ,色差超过肉眼可辨别的范围。结论 相同颜色标号的光敏树脂的颜色极少重合 ,为获得更好的临床颜色效果 。
Objective To compare the color characteristics of the composite resins with the same marks.Methods According to their color marks,those materials were divided into group A2、A3、A 3.5 、B2、B3、C2 and C3.Measure the color of these nine groups of composite resins with the black and white background.Results Obvious color differences were found between each pairs of composite resin partner with the same mark.In each group,the average values of color difference were higher than 3.0 (naked eyes can definitely distinguish).Conclusion Clinically,in order to obtain better color matching,several kinds of composite resins should be simultaneously prepared for selecting.
