这篇研究是通过非破坏性试验储存和定量样本信息，以此阐明影响微拉伸粘接强度(？TBS)各种因素之间的相互关系。研究是通过10颗无龋的人磨牙预备完成？TBS试验样本，并评估影响？TBS试验样本的6个因素：界面存在的空隙，树脂的X线吸收系数，牙本质的X线吸收系数，牙本质部分的长度，粘接区域的大小和牙齿的个体差异性。所有样本在进行？TBS试验前，均非破坏性的通过光学相干断层扫描和micro-CT观察分析。？TBS试验后，影响？TBS数据的上述因素通过普通线性模型、线性混合效应回归模型和非线性回归模型及95%置信区间进行分析。结果显示，使用普通线性模型时，牙齿的个体差异性存在显著性差异( P < 0.001)。在？TBS与牙本质部分的长度之间存在显著的正相关( P < 0.001)；然而，并不存在明显的非线性( P = 0.157)。另外，在？TBS与粘接区域的大小之间存在显著的负相关( P = 0.001)，并伴随明显的非线性( P = 0.014)。在？TBS与树脂的X线吸收系数之间未发现明显的相关性( P = 0.147)，并且也不存在显著的非线性( P = 0.089)。除此

10-甲基丙烯酰氧基癸基二氢磷酸盐（MDP）所包含的底漆能够促进氧化钇稳定的四方晶氧化锆（Y-TZP）和甲基丙烯酸酯树脂之间的粘接。这篇研究的目的是为了检测水对MDP介导的氧化锆-树脂粘接的降解作用。

J Dent：牙科树脂单体对成骨细胞样细胞的体外细胞相容性研究

牙科树脂类材料广泛应用于现代口腔医学中。特别是树脂粘接剂更是享有广泛的流行趋势，并具有多种应用性。然而，树脂基质可以释放树脂单体，随后单体与周围组织相互作用会引起不良的生物学反应，在种植修复术中可能导致种植体周围的骨破坏。因此，这篇研究的目的是为了在体外检测树脂单体对成骨细胞样细胞的细胞毒性。

J Endod：牙本质替代物的粘接效果研究

牙本质替代物对于较大龋损情况下保护牙髓和减小充填材料的膨胀是十分必要的。这些材料与复合树脂修复材料分层充填。如果复合树脂与下层的牙本质替代物之间的粘接效果较差会导致微渗漏的发生，这会进一步引起牙髓损伤。这篇研究的目的是为了观察复合树脂跟牙本质替代物界面的粘接特点，并在实施动态老化后检测剪切粘接强度变化。
