Abstract

Introduction: The purpose of this in vitro study was to investigate the effect of incorporating silver nanoparticles (AgNPs) of herbal origin into mineral trioxide aggregate (MTA) on the push-out bond strength (PBS) and compressive strength (CS) in simulated furcal area perforations.

Materials and methods: In this in vitro study, simulated furcal area perforations (1.3 mm in diameter and 2 mm in depth) were created in 40 extracted human lower molar teeth, which were divided into two groups (n=20): MTA alone and MTA combined with AgNPs (2% wt). Using a universal testing machine, PBS was evaluated by performing push-out tests, while CS was assessed using cylindrical specimens. The normal distribution of data was checked using the Kolmogorov-Smirnov test, and statistical analysis was performed using two-way ANOVA.

Results: The CS results showed no significant difference between the MTA group at 4 and 21 days (P=0.297), but a significant difference was observed in the nanosilver/MTA group (P=0.013). However, there was no significant difference in the push-out bond strength among the study groups (P>0.05).

Conclusion: The incorporation of herbal origin silver nanoparticles did not significantly affect the PBS or CS of MTA.

草药源银纳米颗粒对矿物三氧化物骨料抗压和推出粘结强度的影响。

摘要:本实验旨在探讨将草药银纳米颗粒(AgNPs)掺入三氧化二矿骨料(MTA)中对模拟裂孔区穿孔的推出键强度(PBS)和抗压强度(CS)的影响。材料与方法:在体外实验中，在40颗拔除的人下磨牙上制造直径为1.3 mm、深度为2mm的模拟分叉区穿孔，将其分为单独MTA组和MTA联合AgNPs组(2% wt)两组(n=20)。使用通用试验机，通过进行推出试验来评估PBS，而使用圆柱形试样来评估CS。数据的正态分布检验采用Kolmogorov-Smirnov检验，统计分析采用双因素方差分析。结果:MTA组第4天和第21天CS结果差异无统计学意义(P=0.297)，而纳米银/MTA组CS结果差异有统计学意义(P=0.013)。但各研究组间推出粘结强度差异无统计学意义(P>0.05)。结论:中药银纳米颗粒的掺入对MTA的PBS和CS无显著影响。

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.
