The aim of this study was to evaluate the effect of proanthocyanidin and C. sinensis-polyphenols on microtensile bonding properties of prepared teeth with resin-modified glass ionomer cement (GIC).
This was an in vitro study.
Seventy-eight maxillary premolars were selected and mounted into auto-polymerizing acrylic resin blocks. The samples were prepared and metal crowns were fabricated. The samples were randomly divided into three groups. Samples under Group 1 were not treated with any of the extracts and followed conventional bonding protocol. Samples under Group 2 and Group 3 were treated with proanthocyanidin and C. sinensis-polyphenols, respectively. After dentin treatment, these samples were luted to metal crowns using resin-modified GIC. Universal testing machine was used to measure the load at which the crowns were debonded and microtensile bond strength in MPa was calculated.
The results were statistically analyzed using one-way ANOVA and post hoc Tukey HSD.
Samples treated with C. sinensis polyphenols (Group 3) had maximum bond strength followed by Group 2, where the samples were treated with proanthocyanidin.
C. sinensis polyphenols due to their anti-proteolytic and antioxidant properties showed improved bond strength compared to proanthocyanidin, a cross-linking agent, followed by conventional bonding protocol.
本研究旨在评估原花青素和枳实多酚对用树脂改良型玻璃离子水门汀（GIC）预处理牙的微拉伸粘结性能的影响。
这是一项体外研究。
选择 78 颗上颌前磨牙并将其安装到自聚合丙烯酸树脂块中。对样本进行制备并制作金属冠。将样本随机分为三组。第 1 组样本未用任何提取物处理，并遵循常规粘结方案。第 2 组和第 3 组样本分别用原花青素和枳实多酚处理。在用树脂改良型 GIC 将牙本质处理后的样本粘接到金属冠上后。使用万能试验机测量冠脱落的负荷，并计算以兆帕为单位的微拉伸粘结强度。
使用单因素方差分析和事后 Tukey HSD 对结果进行统计分析。
用枳实多酚处理的样本（第 3 组）具有最大的粘结强度，其次是用原花青素处理的第 2 组，而第 1 组样本未用任何提取物处理。
由于枳实多酚具有抗蛋白水解和抗氧化特性，与交联剂原花青素相比，表现出改善的粘结强度，其次是常规粘结方案。
