J Endod:4种充填材料根尖倒充填时的缝隙大小比较:一项micro-CT评估

2018-04-18 lishiting MedSci原创

这篇研究的目的是为了评估牙本质和根尖充填材料之间缝隙的大小。

这篇研究的目的是为了评估牙本质和根尖充填材料之间缝隙的大小。这篇研究比较了4种根尖充填材料:ProRoot MTA (PRM; Dentsply Tulsa Dental, Tulsa, OK), MTA Angelus (MAG; Angelus, Londrina, Brazil), EndoCem MTA (ECM; Maruchi, Wonju, Korea)和RetroMTA (RTM; BioMTA, Seoul, Korea)。48颗拔除的人单根牙齿使用镍钛器械进行预备,牙胶尖封闭充填。切除根尖3 mm,并使用金刚砂钻预备根尖。根尖窝洞使用4种实验测试根充材料进行充填,分为4个组(n = 10)。随后,样本通过micro-CT影像扫描观察。重建样本的3维影像,并测量牙齿表面(牙本质壁)与根尖充填材料之间的缝隙大小。计算牙齿结构与根尖充填材料之间缝隙大小百分比(VG%)。采用Kruskal-Wallis和 Mann-Whitney U检验对数据进行统计学分析,显著性水平设定为95%。结果显示,PRM, MAG, ECM和RTM组的平均VG%值分别为0.00472, 0.00
