摘要： 目的:评价外源性染色剂对6种树脂水门汀颜色、透明度和表面粗糙度的影响。方法:每种树脂水门汀试样随机分为4组,分别染色于去离子水、可乐、咖啡和红酒。使用色度计和表面粗糙度仪分别测量各组试样染色前及染色48、96、144、192、240和288 h后的色度值(CIE L*、a*、b*)和表面粗糙度值(Ra),据测得色度值计算色差值(ΔE)和透明度参数(TP),用重复测量方差分析和单因素方差分析评估染色时间、染色液和材料对色差值、透明度参数和表面粗糙度值的影响。结果:随染色时间增加,所有材料出现色差值增加、透明度参数降低,表面粗糙度值没有显著性变化。在咖啡和红酒中染色288 h后所有材料染色均超出临床可接受范围(ΔE>3.3),其中红酒染色最明显(ΔE为7.89～12.25)。RelyX U200具有较好的颜色稳定性和透明度稳定性。结论:外源性染色剂对树脂水门汀颜色和透明度的影响具有材料依赖性。288 h后6种树脂水门汀均出现肉眼可察觉的变色(ΔE>1)。

Abstract: Objective: To evaluate the effect of staining solutions on color, translucency, and surface roughness of contemporary resin cements. Methods: Six commercially available resin cements were investigated in the present study. For each material, twenty cylinder-shaped specimens with 10 mm in diameter and 1 mm in thickness were prepared and randomly divided into four groups. The specimens were immersed in 4 different solutions (deionized water, cola, coffee, and red wine) for 288 hours. The color parameters and surface roughness of specimens were measured before and after staining solutions for 48 h, 96 h, 144 h, 192 h, 240 h and 288 h. The color differences (ΔE values) and translucency parameter (TP) between baseline and post-treatments were calculated. Repeated measures ANOVA and one-way ANOVA with a significance level of 0.05 was used to evaluate the effect of immersion time, staining solutions, and materials on color difference (ΔE), translucency parameter (TP) and surface roughness (Ra). Results: Immersion in staining solutions produced similar behavior in time for all tested materials that ΔE was increased, TP was decreased and surface roughness did not change obviously. After 288 h immersion in coffee and red wine, all materials showed color changes above the clinically accepted value (all ΔE>3.3) and red wine induced the most pronounced color differences (ΔE=7.89~12.25). RelyX U200 showed higher color and TP stability compared to the other resin cements. The color stability of most light-cured resin cements was superior to that of dual-cured type. Conclusion: The effects of staining solutions on the color and translucency of resin cements are material dependent. However, all specimens show discoloration after completion of the test period which is visually perceptible (all ΔE>1).
