这篇研究的目的是为了评估不同损伤封闭疗法对人造非窝洞釉质损伤的纳米微渗漏。研究使用32颗人的前牙作为试验对象。在牙齿唇面人为构建釉质表面下损伤。随后,样本随机分为3组(n=10):组1-应用Clinpro Sealant;组2-应用ExciTE F adhesive resin;组3-应用ICON resin infiltrant。每组进一步再分为2个亚组:对照组和热循环组。通过数字影像分析软件对纳米微渗漏进行评估。结果显示,在对照组和热循环组中,对于组1/2/3之间未发现显著性差异(p>0.05)。仅在组3中的对照组和热循环组微渗漏值之间存在明显的差异(p=0.027)。结论:ICON infiltrant可以作为牙齿粘接剂以及封闭最初非窝洞釉质损伤的隐裂封闭剂的一种替代选择。但是随着时间的推移,树脂比其他材料更易受到吸水作用的影响。另外,还需更多的研究来评估树脂渗透剂的长期耐久性。原始出处:Arslan S, Lipski L, et al.
