The present study was aimed to evaluate and compare the apical sealing ability of two endodontic root-end filling materials namely, iRoot SP (ceramic based) and ProRoot MTA using the bacterial leakage system.
A total of fifty recently extracted, single rooted teeth with a single straight canal were selected for the study. The teeth were chemo mechanically prepared. The apical 3mm of the root was resected and root end cavities were prepared. The teeth were randomly divided into two groups of twenty teeth each for the experimental root end filling materials namely, iRoot SP and ProRoot MTA. A two-chamber model was constructed using pippeter tips and plastic vials. The pipetter tips with the teeth were suspended in these caps and the entire assembly was reattached to the vial. The upper chamber was seeded with. An Enterococci-selective broth was used in the lower chamber. Leakage was assessed for 90 days and compared using survival statistics.
The ProRoot MTA filled root end samples leaked within 30-72 days. The iRoot SP filled root end samples leaked within 51-69 days.
Under the parameters of this study, it can be concluded that all the tested materials showed significant apical sealing ability as root-end filling materials over a period of 90 days. iRoot SP exhibited the most effective apical sealing ability as compared to ProRoot MTA.

本研究旨在使用细菌渗漏系统评估和比较两种牙髓根尖充填材料iRoot SP(陶瓷基)和ProRoot MTA的根尖封闭能力。
共选择50颗近期拔除的、单根单根管的牙齿用于本研究。对牙齿进行化学机械预备。切除根尖3mm的牙根并制备根尖腔。将牙齿随机分为两组,每组20颗,分别用于实验性根尖充填材料iRoot SP和ProRoot MTA。使用移液器吸头和塑料小瓶构建双腔模型。将带有牙齿的移液器吸头悬挂在这些瓶盖中,并将整个组件重新连接到小瓶上。在上腔接种。在下腔使用肠球菌选择性肉汤。评估90天的渗漏情况,并使用生存统计进行比较。
ProRoot MTA充填的根尖样本在30 - 72天内发生渗漏。iRoot SP充填的根尖样本在51 - 69天内发生渗漏。
在本研究的参数下,可以得出结论,在90天的时间内,所有测试材料作为根尖充填材料均显示出显著的根尖封闭能力。与ProRoot MTA相比,iRoot SP表现出最有效的根尖封闭能力。根尖封闭能力、细菌渗漏、iRoot SP、ProRoot MTA、根尖充填。
