粘固水泥的边缘变色可能会影响美观修复体的外观。本研究评估了当前粘合树脂水门汀在咖啡中浸泡后的颜色稳定性。对四种双固化树脂水门汀（Clearfil SA 水门汀 Automix Universal、Maxcem Elite Clear、Maxcem Elite Yellow 和 RelyX Unicem2 Automix A2）和两种化学固化树脂水门汀（Super-Bond C&B Clear 和 Super-Bond C&B Esthetic）进行了检查。使用分光光度计在白色背景上测量 2.0 毫米厚的圆盘状样品的 CIE L*a*b* (n = 6)。选择浸泡溶液和产品作为主要因素，通过双向方差分析分析在 37°C 水或咖啡中浸泡 1 天和 1 周后的颜色差异（匕首 E），然后进行 Tukey 的 HSD 测试（α = 0.05）。还评估了吸水性和溶解度。a dagger Es 的双向方差分析表明这两个主要因素及其相互作用是显着的。除 Super-Bond C&B Esthetic 外，咖啡浸泡后的匕首 Es 明显大于水浸泡后的。各产品浸水后的匕Es没有显着差异； Maxcem Elite Clear 和 Maxcem Elite Yellow 在咖啡浸泡后的浓度明显高于其他样品。吸水率和溶解度与a 匕首Es 显着相关。在咖啡浸泡1 周后检测的粘合树脂水门汀的a 匕首Es 在产品之间存在显着差异。产品表现出更大的吸水性和溶解度，显示出更大的颜色变化。当陶瓷修复体的边缘外观很重要时，应仔细选择粘合树脂水门汀。
Marginal discoloration of luting cement may affect the appearance of esthetic restorations. This study evaluated the color stability of current adhesive resin cements after immersion in coffee.Four dual-cured resin cements (Clearfil SA cement Automix Universal, Maxcem Elite Clear, Maxcem Elite Yellow, and RelyX Unicem2 Automix A2) and two chemical-cured resin cements (Super-Bond C&B Clear and Super-Bond C&B Esthetic) were examined. The CIE L*a*b* of 2.0-mm-thick disc-shaped specimens was measured using a spectrophotometer on a white background (n = 6). The color differences (a dagger E) after 1-day and 1-week immersion in 37 A degrees C water or coffee were analyzed by two-way ANOVA by selecting immersion solution and product as main factors, followed by Tukey's HSD test (alpha = 0.05). Water sorption and solubility were also evaluated.The two-way ANOVA of the a dagger Es suggested that the two main factors and their interaction were significant. The a dagger Es after coffee immersion were significantly greater than those after water immersion, except for Super-Bond C&B Esthetic. The a dagger Es after water immersion were not significantly different among the products; those of Maxcem Elite Clear and Maxcem Elite Yellow after coffee immersion were significantly greater than the others. The water sorption and solubility significantly correlated with the a dagger Es.The a dagger Es of the adhesive resin cements examined after 1-week coffee immersion were significantly different among the products. The product showing greater water sorption and solubility displayed greater color change.Adhesive resin cements should be carefully selected when the marginal appearance of the ceramic restoration is important.
