背景:AHPlus,环氧树脂基密封剂,广泛用于牙髓实践,由于其良好的物理性能,赋予长期的尺寸稳定性和良好的粘附牙本质。然而,它有引发炎症的倾向,尤其是在它刚刚混合的状态下,已被广泛记录。植物化学物质,如Petasin,赤霉酸,姜黄素,和Shilajit以其抗炎和镇痛作用而闻名。本研究旨在分析和确定这些天然产物对AHPlus密封剂掺入密封剂时的物理性质的影响。
方法:将AHPlus(AHR)封口剂与10%petasin混合,0.75%的胞嘧啶,0.5%和6%的shilajit获得AHP,AHA,AHC和AHS的比例分别为10:1和5:1。评估每种材料的五个样品的凝固时间,溶解度,流量,和尺寸稳定性符合ISO6876:2012标准。通过扫描电子显微镜(SEM)对密封剂进行了表征,X射线能量色散谱,X射线衍射(XRD)和傅里叶变换红外(FTIR)光谱。统计评估涉及Kolmogorov-Smirnov和Shapiro-Wilks正态检验和单向ANOVA检验进行分析。
结果:在这项调查中,表征分析显示,在所有的实验根管封闭剂的微观结构相对相似。所有实验组,不包括对照组,在10:1的比例下,流量从11.9增加到31.4%。同样,对于5:1的比例,增幅由12.02至31.83%不等。在尺寸稳定性方面,与对照组相比,10:1比例的所有组均显示下降.以10:1的比例向AHR中添加天然试剂导致凝固时间减少8.9-31.6%,以5:1的比例,下降幅度为8.1%至31.5%。然而,关于溶解度,天然药物的添加没有引起任何显著的改变.
结论:根据本研究的结果,可以得出结论,所有测试的根管密封剂的性能均符合ISO6876:2012标准化中概述的可接受标准.
BACKGROUND: AH Plus, an epoxy resin-based sealer, is widely used in endodontic practice, owing to its good physical properties that confers longstanding dimensional stability and good adhesion to dentin. Nevertheless, its propensity to trigger inflammation, especially in its freshly mixed state, has been extensively documented. Phytochemicals such as Petasin, Pachymic acid, Curcumin, and Shilajit are known for their anti-inflammatory and analgesic effects. This
study aimed to analyze and determine the effect of these natural products on the physical properties of AH Plus sealer when incorporated with the sealer.
METHODS: AH Plus (AHR) sealer was mixed with 10% petasin, 0.75% pachymic, 0.5% and 6%shilajit to obtain AHP, AHA, AHC and AHS in the ratio of 10:1 and 5:1 respectively. Five samples of each material were assessed for setting time, solubility, flow, and dimensional stability in accordance with the ISO 6876:2012 standardization. Sealers were characterized through scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy, X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy. Statistical evaluation involved the Kolmogorov-Smirnov and Shapiro-Wilks tests for normality and the one-way ANOVA test for analysis.
RESULTS: In this investigation, the characterisation analysis revealed a relatively similar microstructure in all the experimental root canal sealers. All experimental groups, excluding the control group, exhibited an increase in flow ranging from 11.9 to 31.4% at a 10:1 ratio. Similarly, for the 5:1 ratio, the increase ranged from 12.02 to 31.83%. In terms of dimensional stability, all groups at the 10:1 ratio showed a decrease compared to the control group. The addition of natural agents to AHR in 10:1 ratio led to a reduction in setting time by 8.9-31.6%, and at a 5:1 ratio, the reduction ranged from 8.1 to 31.5%. However, regarding solubility, the addition of natural agents did not induce any significant alterations.
CONCLUSIONS: Based on the results of this
study, it can be concluded that all tested root canal sealers exhibited properties that met the acceptable criteria outlined in the ISO 6876:2012 standardization.
