To evaluate the effect of chlorhexidine-loaded halloysite aluminosilicate clay nanotube (HNT) incorporation into a two-step etch-and-rinse (ONE-STEP) and a self-etch (XENO Ⅴ) adhesive on human dentin tensile shear strength (TSS).
Ten groups (n=12) were prepared according to the adhesive system and amount of CHX/HNT incorporated (5%, 10%, 15%) as follows: XE control(A1), XE experimental control (A2), 5% CHX/HNT-XE (A3), 10%CHX/HNT-XE (A4), 15% CHX/HNT-XE (A5), OS control (B1), OS experimental control (B2), 5% CHX/HNT-OS (B3), 10% CHX/HNT-OS (B4), 15% CHX/HNT-OS (B5). TSS testing was performed after 24 h. Scanning electron microscopy of the resin-dentin interface of selected specimens was carried out. One-way ANOVA was used to evaluate the TSS date in XE groups and OS groups. Two-way ANOVA was used to evaluate the effect of the adhesive system and the CHX/HNT content on dentin TSS with SPSS 19.0 software package.
The TSS date of 5% CHX/HNT-XE was significantly higher than the other groups. The TSS date of 10% CHX/HNT-OS was significantly higher than the other groups (P<0.05). No significant difference was detected between adhesive systems and dentin TSS. significant difference was found between CHX/HNT content and dentin TSS.
CHX/HNT addition into dentin adhesive increased bond strength to dentin.
评估将载有洗必泰的埃洛石铝硅酸盐粘土纳米管（HNT）加入两步酸蚀冲洗（一步法）和自酸蚀（XENOⅤ）粘合剂中对人牙本质拉伸剪切强度（TSS）的影响。
根据粘合剂系统以及加入的CHX/HNT量（5%、10%、15%）制备十组（n = 12），具体如下：XE对照组（A1）、XE实验对照组（A2）、5% CHX/HNT-XE（A3）、10% CHX/HNT-XE（A4）、15% CHX/HNT-XE（A5）、OS对照组（B1）、OS实验对照组（B2）、5% CHX/HNT-OS（B3）、10% CHX/HNT-OS（B4）、15% CHX/HNT-OS（B5）。24小时后进行TSS测试。对选定标本的树脂-牙本质界面进行扫描电子显微镜检查。使用单因素方差分析评估XE组和OS组的TSS数据。使用双因素方差分析，通过SPSS 19.0软件包评估粘合剂系统和CHX/HNT含量对牙本质TSS的影响。
5% CHX/HNT-XE的TSS数据显著高于其他组。10% CHX/HNT-OS的TSS数据显著高于其他组（P<0.05）。在粘合剂系统和牙本质TSS之间未检测到显著差异。在CHX/HNT含量和牙本质TSS之间发现了显著差异。
向牙本质粘合剂中添加CHX/HNT可提高与牙本质的粘结强度。
