The present study aimed to comparatively evaluate the shear bond strength (SBS) of one light-cure and two dual-cure resin cement to bond lithium disilicate veneers.
Thirty maxillary central incisors ( = 30) were procured and randomly divided into three groups of adhesive/resin cement systems, into groups of 10 each ( = 10); Group A: Adper Single Bond 2/RelyX Veneer Cement, Group B: Prime and Bond NT/Calibra, and Group C: Excite DSC/Variolink II. All the tooth samples were etched and respective bonding agent was applied. Similarly, all the laminate veneer specimens were etched, silanated, and treated with respective bonding agents before cementation with the respective resin cement. The SBS was measured in a universal testing machine with a cross-head speed of 1 mm/min.
Data obtained were analyzed using the one-way analysis of variance and post hoc Tukey's test at a 5% significance level.
The highest SBS was demonstrated by Group C (18.8 ± 0.92 Mpa), followed by Group B (18.4 ± 0.74) Mpa, and the least by Group A (17.4 ± 0.75 MPa). Significant differences were found between Group A, Group B, and Group C, respectively. However, Group B and Group C did not differ significantly from each other.
Dual-cure resin cement have higher SBS than the light-cure variants.
本研究旨在比较评估一种光固化树脂水门汀和两种双固化树脂水门汀对二硅酸锂贴面的剪切粘结强度（SBS）。
获取30颗上颌中切牙（n = 30），随机分为三组粘结剂/树脂水门汀系统，每组10颗（n = 10）；A组：Adper Single Bond 2/RelyX Veneer Cement，B组：Prime and Bond NT/Calibra，C组：Excite DSC/Variolink II。所有牙齿样本均进行酸蚀并应用相应的粘结剂。同样，所有层压贴面标本在与相应的树脂水门汀粘结之前均进行酸蚀、硅烷化处理并使用相应的粘结剂处理。在万能试验机上以1 mm/min的十字头速度测量SBS。
所获数据采用单因素方差分析和事后Tukey检验进行分析，显著性水平为5%。
C组的SBS最高（18.8±0.92 Mpa），其次是B组（18.4±0.74）Mpa，A组最低（17.4±0.75 Mpa）。A组、B组和C组之间分别存在显著差异。然而，B组和C组之间无显著差异。
双固化树脂水门汀的SBS高于光固化树脂水门汀。
