Dentistry has found practically the best available aesthetic answer, is ceramic restoration. There are various factors that contribute to the success of ceramic veneers, like colour of underlying tooth, thickness if ceramics and the type of underlying luting cement. Shade selection and matching remains still challenge, however the shade of luting agent used for cementation of veneers produces a change in resultant shade of veneers.
To compare and analyze the spectrophotometric effect of opaque and transparent luting agent on resultant shade of ceramic veneers made of 2L1.5 shade (Vitapan 3D-Masters) and B2 shade (Vitapan Classic).
Out of 15 ceramic veneers of 2L1.5 shade (VITAPAN 3D- Master), seven teeth cemented with opaque cement and eight teeth with transparent cement shade of dual cure resin cement (Variolink II(TM)). Out of 10 ceramic veneers of B2 shade (VITAPAN Classic), five teeth were cemented with opaque cement and other five teeth with transparent cement shade of dual cure resin cement (Variolink II(TM)). Spectrophotometric (Macbeth U.S.A.) analysis of all ceramic veneer crowns done with optiview software and readings were recorded in Commission Internationale de I' Eclairge {CIELAB} system and dE value was calculated.
Statistical analysis was done by using Paired t-test.
Spectrophotometric analysis of all the veneers cemented with opaque luting agent were lighter in shade due to significant change in dL value. Veneers cemented with transparent luting agent were darker in shade due to significant change in the dL value.
Opaque luting agent gives lighter shade and transparent luting agent gives darker shade to ceramic veneers fabricated with 2L1.5 and B2 shades.
牙科领域几乎找到了最佳的美学解决方案，即陶瓷修复。有多种因素会影响陶瓷贴面的成功，比如基牙的颜色、陶瓷的厚度以及底层粘结水门汀的类型。选色和配色仍然是一项挑战，然而用于贴面粘结的粘结剂颜色会使贴面的最终颜色发生变化。
比较和分析不透明和透明粘结剂对由2L1.5色（维他灵3D-Masters）和B2色（维他灵经典版）制成的陶瓷贴面最终颜色的分光光度影响。
在15个2L1.5色（维他灵3D-Masters）的陶瓷贴片中，7颗牙用不透明粘结剂粘结，8颗牙用双固化树脂粘结剂（Variolink II™）的透明粘结剂粘结。在10个B2色（维他灵经典版）的陶瓷贴片中，5颗牙用不透明粘结剂粘结，另外5颗牙用双固化树脂粘结剂（Variolink II™）的透明粘结剂粘结。使用Macbeth美国分光光度计和optiview软件对所有陶瓷贴面冠进行分光光度分析，并在国际照明委员会（CIELAB）系统中记录读数，计算dE值。
采用配对t检验进行统计分析。
用不透明粘结剂粘结的所有贴面的分光光度分析显示，由于dL值的显著变化，颜色更浅。用透明粘结剂粘结的贴面由于dL值的显著变化，颜色更深。
对于用2L1.5色和B2色制作的陶瓷贴面，不透明粘结剂会使其颜色变浅，透明粘结剂会使其颜色变深。
