目的：评价全瓷贴面用不同类型树脂粘接并加速老化后的颜色稳定性和不透光度变化。方法：用IPS e．max PressA1色瓷块制作厚0．4 mm、直径10 mm的瓷片28片，随机分为4组（n＝7），分别用BEAUTIFIL Flow、DEO-Link SE、Panavia F、Vi-riolink N粘接，LED光固化灯照40 s。将0．5 mm厚瓷贴面树脂复合体放入环境模拟器中加速老化，数字比色仪测量老化前后的颜色值，用CIE L*a*b*颜色系统计算颜色值变化量ΔE和不透光度变化值ΔO，用ANOVA，LSD（L）进行统计学分析。结果：所有材料均有明显的颜色值和不透光度变化。ΔE范围0．6～2．29，其中BEAUTIFIL Flow颜色变化最小，DEO-Link变化较大。ΔO为0．46～2．55。Panavia F不透光度增加最多（P＜0．05）。结论：加速老化可导致所有测试材料颜色变化，但变化量在临床可接受范围之内（ΔE＜3）。

Objective:To assess the effect of accelerated aging on the color and opacity of veneers bonded resin.Methods:28 discs were made with IPS e.max Press A1 shade with the thickness of 0.4 mm.Ceramic discs were divided into 4 groups(n=7). BEAUTIFIL Flow A1 ,DEO-Link SE Transparent,Panavia F Light color and Viriolink N transparent resin cements were applied on the porcelain discs with a thickness of 0.1 mm.Curing was performed with a calibrated LED curing-light for 40 seconds.Color and opac-ity differences of the porcelain substructures after 65 h(150 kJ/m2 )of UV ageing test were examined with a colorimeter.The results were analysed statistically with One-way ANOVA,LSD(L)test.Results:All samples showed significant changes in color and opaci-ty.The ΔE of all materials ranged from 0.6 to 2.29.DEO-Link SE showed the highest color change,while BEAUTIFIL Flow the lowest.The opacity changes ranged from 0.46 to 2.55 and its variation was not significant among groups except for Panavia F.Con-clusion:The accelerated ageing may lead to color changes of ceramic veneer bonded by resins in a clinically acceptable range(ΔE<3).
