The coronal leakage of bacteria and other irritants to the root canal system is one of the main factors that may result in clinical failure and affect the long term success of endodontic treatment. The Resilon/Epiphany obturation system has been developed as an alternative to gutta-percha and traditional sealers.
This study aimed to evaluate and compare the coronal leakage between Resilon obturation material and gutta-percha using the same sealer.
In this in-vitro study, 72 freshly extracted single-rooted human teeth were used, and were sectioned at CEJ with 13mm length. The roots were randomly divided into four groups. In Group I, 30 roots were obturated using Resilon and Epiphany SE sealer, Group II, 30 roots were obturated using gutta-percha and Epiphany SE. Group III and Group IV, 12 roots were used as control groups (positive and negative). The coronal leakage was measured using the dye penetration technique. Data were statistically analysed by a One-Way ANOVA test.
There was a significant difference between the two experimental groups where Resilon revealed less microleakage than gutta-percha group (p <0.05).
Resilon is a suitable replacement for gutta-percha on the basis of its increased resistance to microleakage, but it failed to provide complete hermetic coronal sealing.
细菌及其他刺激物向根管系统的冠方渗漏是可能导致临床治疗失败并影响牙髓治疗长期成功率的主要因素之一。Resilon/Epiphany根管充填系统已被开发出来作为牙胶和传统封闭剂的替代品。
本研究旨在评估和比较使用相同封闭剂时Resilon充填材料与牙胶之间的冠方渗漏情况。
在这项体外研究中，使用了72颗新鲜拔除的单根人牙，并在牙釉质牙骨质界处将其截为13毫米长。将牙根随机分为四组。第一组，30个牙根使用Resilon和Epiphany SE封闭剂进行充填；第二组，30个牙根使用牙胶和Epiphany SE进行充填。第三组和第四组，12个牙根用作对照组（阳性和阴性）。使用染料渗透技术测量冠方渗漏情况。数据通过单因素方差分析进行统计学分析。
两个实验组之间存在显著差异，Resilon组的微渗漏比牙胶组少（p <0.05）。
基于Resilon对微渗漏的抵抗力增强，它是牙胶的合适替代品，但它未能提供完全密封的冠方封闭。
