BACKGROUND
The aim of this in vitro study was to evaluate the depth of penetration of 4 different endodontic resin sealers into the radicular dentinal tubules with the aid of confocal microscopy.
METHODS
Eighty single-rooted teeth were instrumented and divided into 4 groups composed of 20 teeth each. The samples were obturated with AH Plus, RealSeal, EndoRez, and RoekoSeal resin sealers, respectively. The core material in all the groups was Resilon. The teeth were sectioned at the coronal, middle, and apical thirds and viewed under confocal microscope to determine the depth of penetration of the sealer into the dentinal tubules.
RESULTS
The results showed that the maximum penetration was exhibited by RealSeal resin sealer, followed by AH Plus, RoekoSeal, and EndoRez. The coronal third showed the maximum penetration, followed by middle third and least at the apical third.
CONCLUSION
Under the parameter of this study, RealSeal resin sealer exhibited the maximum penetration.
背景
本体外研究旨在借助共聚焦显微镜评估 4 种不同根管封闭剂在根管牙本质小管中的渗透深度。
方法
将 80 颗单根牙进行器械处理并分为 4 组，每组 20 颗牙。分别用 AH Plus、RealSeal、EndoRez 和 RoekoSeal 树脂封闭剂对样本进行填充。所有组的核心材料均为 Resilon。在根管牙本质中，将牙齿在冠、中、根尖三分之一处进行切割，并在共聚焦显微镜下观察，以确定封闭剂进入牙本质小管的深度。
结果
结果表明，RealSeal 树脂封闭剂的最大渗透深度最大，其次是 AH Plus、RoekoSeal 和 EndoRez。冠部三分之一处显示最大的渗透深度，其次是中部三分之一，根尖三分之一处最少。
结论
在本研究参数下，RealSeal 树脂封闭剂显示出最大的渗透深度。
