Adequate bond strength between glass ionomer cements and composite resin is necessary for the success of the sandwich technique.
This study assessed the micro-shear bond strength of composite resin to glass-ionomer cements (GIC) using self-etch adhesives with different pH values.
One hundred specimens (6×4×2 mm) were made using Fuji II and Fuji II LC GICs and treated with different adhesives as follows: Group 1:Fuji II+ Adper Prompt L-Pop, Group-2: Fuji II+SE bond, Group-3: Fuji II + AdheSE, Group-4:Fuji II+ Protect bond, Group-5: Fuji II + Single bond, Group-6:Fuji II LC+ Adper Prompt LPop, Group-7: Fuji II LC+SE bond, Group-8:Fuji II LC+ AdheSE, Group-9: Fuji II LC+ Protect bond, and Group-10: Fuji II LC+ Single bond. Each group consisted of 10 specimens. A cylinder of Z100 composite resin was placed on each sample and light cured. After 24 hours of water storage (37°C), the specimens were subjected to micro-shear bond strength tests (0.5 mm/min). Data were analyzed using two-way ANOVA and Tukey's test.
The mean micro-shear bond strength of groups 1-10 was 11.66±1.79, 16.50±1.85, 18.47±1.77, 13.95±1.77, 15.27±1.49, 15.14±0.90, 20.03±1.19, 17.48±3.00, 16.24±1.98 and 16.03±1.49 MPa, respectively. There were significant differences between groups 1 and 7 (P<0.05). No significant difference was observed between other groups (P>0.05). Fuji II LC showed higher bond strength than Fuji II (P<0.05).
Type of self-etch adhesive had no significant effect on micro-shear bond strength of glass-ionomer to composite resin. Resin modified glass ionomer cement (RMGIC) exhibited higher bond strength than the conventional GIC.
对于夹层技术的成功而言，玻璃离子水门汀与复合树脂之间具备足够的粘结强度是必要的。
本研究使用具有不同pH值的自酸蚀粘结剂评估复合树脂与玻璃离子水门汀（GIC）的微剪切粘结强度。
使用富士II型和富士II型LC玻璃离子水门汀制作100个样本（6×4×2毫米），并使用不同的粘结剂进行处理，如下所示：第1组：富士II型+Adper Prompt L-Pop，第2组：富士II型+SE粘结剂，第3组：富士II型+AdheSE，第4组：富士II型+Protect bond，第5组：富士II型+Single bond，第6组：富士II型LC+Adper Prompt L-Pop，第7组：富士II型LC+SE粘结剂，第8组：富士II型LC+AdheSE，第9组：富士II型LC+Protect bond，第10组：富士II型LC+Single bond。每组包含10个样本。将Z100复合树脂圆柱体放置在每个样本上并进行光固化。在37°C的水中储存24小时后，对样本进行微剪切粘结强度测试（0.5毫米/分钟）。使用双向方差分析和Tukey检验对数据进行分析。
第1 - 10组的平均微剪切粘结强度分别为11.66±1.79、16.50±1.85、18.47±1.77、13.95±1.77、15.27±1.49、15.14±0.90、20.03±1.19、17.48±3.00、16.24±1.98和16.03±1.49兆帕。第1组和第7组之间存在显著差异（P<0.05）。其他组之间未观察到显著差异（P>0.05）。富士II型LC显示出比富士II型更高的粘结强度（P<0.05）。
自酸蚀粘结剂的类型对玻璃离子与复合树脂的微剪切粘结强度没有显著影响。树脂改性玻璃离子水门汀（RMGIC）表现出比传统玻璃离子水门汀更高的粘结强度。
