摘要：

目的研究粘固剂的色调、厚度变化对Solidex树脂试样颜色的影响。方法将不同厚度（0.1、0.2 mm）及色调（A1、A3）的粘固剂放于不同底色材料（镍铬合金、A3和C3色调的充填性树脂、遮色瓷饰面的镍铬合金）与不同厚度（0.5、1.0 、1.5 mm）的Solidex树脂试样之间，使用ShadeEye NCC测色仪测定Solidex树脂试样的颜色，计算在相同底色材料下，Solidex树脂试样采用不同厚度和色调粘固剂时的色差（△E*）。结果粘固剂的色调、厚度变化对Solidex树脂试样表面色差△E*均有显著影响，并且这种影响受到试样厚度、底色材料的交互作用（P<0.001）。粘固剂厚度变化中，A3色调粘固剂对0.5 mm厚度Solidex树脂试样表面颜色的色差△E*>2，为临床所不可接受。粘固剂色调变化中，0.2 mm厚度粘固剂对0.5 mm和1.0 mm厚Solidex树脂试样的色差△E*>2。结论粘固剂的色调及厚度变化可明显改变较薄的Solidex树脂试样表面颜色。

Abstract:

Objective To evaluate the effect of the shade and thickenss of luting agent on the final color of different thickness Solidex resin in vitro. Methods Five specimens of Solidex resin were fabricated at thickness of 0.5, 1.0 and 1.5 mm. The pieces of Ni- Cr alloy, two shade composite resin and opaque porcelain veneered Ni- Cr alloy were used as backgrounds. The CIE L*a*b* values of specimens were measured by a colorimeter（ShadeEye NCC） to determine the colorimetric difference, when different thickness of specimens were overlaid the different shade and thickness of luting agent at the same backgrounds. Results The final color difference of specimens was significantly influenced by the factors of luting agent and the interaction of specimens thickness, backgrounds and luting agent（P< 0.001）. Regarding the thickness of luting agent, A3 shade luting agents produced clinically unacceptable difference （△E*>2）in the final color of Solidex specimens at the thickness of 0.5 mm. Regarding the shade of luting agent, the color difference was more than 2 when the Solidex specimens at the thickness of 0.5 mm or 1.0 mm were against the 0.2 mm thick luting agent. Conclusion The final color of thinner Solidex specimens was significant affected by the change of the shade and thick of luting agent.
