Abstract

Introduction: Achieving a three-dimensional seal in the apical, lateral, and coronal regions of the root canal is a key objective in endodontic treatment. This study aimed to compare the apical sealing ability of NeoSealer Flo, MTA-Fillapex, and AH-26 over different time intervals using the fluid filtration method.

Materials and methods: In this in vitro study, 58 single-rooted premolars (n=18 per group; 2 positive and 2 negative controls) were selected and prepared using the ProTaper system up to file F3. Canals were obturated with the single-cone technique using one of the three tested sealers. Apical microleakage was measured at 24 hours, 1 week, and 4 weeks using the fluid filtration method. Data were analyzed using one-way ANOVA, repeated measures ANOVA, ANCOVA, and Tukey's HSD post hoc test (P<0.05).

Results: The results indicated that sealer type, time, and their interaction had a statistically significant effect on apical microleakage (P<0.001). NeoSealer Flo showed the lowest and AH-26 the highest leakage values across all time intervals. In all three groups, microleakage decreased over time. This reduction was statistically significant from 24 hours to 1 week in the NeoSealer Flo and MTA-Fillapex groups (P<0.001), and from 1 week to 4 weeks in the AH-26 group (P<0.05).

Conclusion: Within the limitations of this study, NeoSealer Flo demonstrated superior apical sealing ability at all time points. Under single-cone obturation conditions, bioceramic sealers such as NeoSealer Flo may provide more predictable long-term apical sealing compared to resin-based alternatives.

生物陶瓷和树脂基密封剂的尖端密封性能比较：流体过滤分析。

在根管的根尖、侧边和冠状区域实现三维密封是根管治疗的关键目标。本研究旨在通过流体过滤法比较NeoSealer Flo、MTA-Fillapex和AH-26在不同时间间隔内的根尖密封能力。材料和方法：在体外研究中，选择58颗单根前磨牙（每组18颗，阳性对照2颗，阴性对照2颗），使用ProTaper系统制备至锉F3。使用三种测试封口剂中的一种，用单锥技术封闭根管。分别于24小时、1周和4周采用液体滤过法测量根尖微漏。数据分析采用单因素方差分析、重复测量方差分析、方差分析和Tukey’s HSD事后检验（结果：封口剂类型、时间及其相互作用对根尖微渗漏有统计学显著影响）。结论：在本研究的局限性内，NeoSealer Flo在所有时间点都表现出优越的根尖密封能力。在单锥封闭条件下，生物陶瓷密封剂（如NeoSealer Flo）与树脂基密封剂相比，可以提供更可预测的长期根尖密封。

期刊介绍： The Iranian Endodontic Journal (IEJ) is an international peer-reviewed biomedical publication, the aim of which is to provide a scientific medium of communication for researchers throughout the globe. IEJ aims to publish the highest quality articles, both clinical and scientific, on all aspects of Endodontics. The journal is an official Journal of the Iranian Center for Endodontic Research (ICER) and the Iranian Association of Endodontists (IAE). The Journal welcomes articles related to the scientific or applied aspects of endodontics e.g. original researches, systematic reviews, meta-analyses, review articles, clinical trials, case series/reports, hypotheses, letters to the editor, etc. From the beginning (i.e. since 2006), the IEJ was the first open access endodontic journal in the world, which gave readers free and instant access to published articles and enabling them faster discovery of the latest endodontic research.
