摘要
目的:观察不同树脂水门汀对模拟四环素牙瓷贴面修复体色彩学的影响。方法:制备四环素牙模拟背景后,使用不同的树脂水门汀(包括A1、A3色RelyX veneer光固化树脂水门汀,浅色、白色Panavia F双重固化复合树脂水门汀)进行瓷贴面修复,测量修复前后瓷贴面试件表面的L*a*b*值。结果:使用不同树脂水门汀对瓷贴面试件表面的L*a*b*值有影响(P(0.05),Dunnett-t检验结果显示Panavia F白色组的L*a*b*值与对照组之间的差异无统计学意义(P>0.05);使用Panavia F白色树脂水门汀黏结前后,瓷贴面试件表面颜色的色差△E(1.5,不易为肉眼识别;使用其余各树脂水门汀时,瓷贴面试件表面颜色的色差均>1.5,肉眼可以分辨。结论:在四环素牙贴面修复过程中可通过调节树脂水门汀的颜色来调整修复体的颜色,用Panavia F白色树脂水门汀进行黏结,可使修复体达到更理想的修复效果。
AIM：To observe the influence of different resin cements on the esthetic results of veneer restorations for tetracycline stained tooth. METHODS： Ceramic veneers were bonded to artificiallly stained background with different resin cements, including A1-and A3-shade of the RelyX veneer light-curing system, light-and opaque-shade of Panavia F double-curing system, and opaque-, A2-and A3-shade of the RelyX Unicem double-curing system. The L^＊a^＊b^＊ values of different restorations were recorded and compared. RESULTS： L^＊a^＊b^＊ values were significantly different （P0.005） among different groups. Dunnett-t results showed that there was no statistical significance between the L^＊a^＊b^＊ values of control group and opaque-shade of Panavia F group.The total color difference △E between control group and opaque- shade of Panavia F group was﹤1.5, whereas △E was﹥1.5 among the others groups. CONCLUSION：The esthetic outcome of veneer restorations for tetracycline pigmentation tooth can be adjusted by trying resin cements with different colors. Opaque-shade of Panavia F double-curing cement shows nicer masking capability as compared with other resins.
