背景:这项研究的目的是评估两种新引入的基于预混合硅酸钙的根管封闭剂(AHPlusBiocamicSealer和Bio-CSealer)与基于树脂的根管封闭剂(ADseal根管封闭剂)的理化性能。
方法:溶解度,pH分析,钙离子释放,每个密封剂的膜厚度根据ISO指南进行评估。使用双向ANOVA检验检查数据。此外,进行X射线衍射(XRD)检查以研究每种类型的密封剂的结晶相。进行X-射线荧光(XRF)分析用于每种密封剂的化学元素分析。
结果:薄膜厚度最小,最高碱度,AHPlus生物陶瓷密封剂显示钙离子释放量最高。高溶解度,高碱度,中间钙离子释放,和中间膜厚度均由Bio-CSealer显示。当ADseal根管封闭剂显示最大的膜厚度时,最小溶解度,碱度,和钙离子释放。
结论:AHPlus生物陶瓷密封剂和Bio-C密封剂都表现出足够的性能,被认为是一种良好的密封剂,可以用作树脂基根管密封剂的潜在替代品。
BACKGROUND: The aim of this study was to evaluate the physicochemical properties of two newly introduced premixed calcium silicate-based root canal sealers (AH Plus Bioceramic Sealer and Bio-C Sealer) compared to a resin-based root canal sealer (ADseal root canal sealer).
METHODS: Solubility, pH analysis, calcium ion release, and film thickness of each sealer were evaluated following ISO guidelines. The data were examined using the two-way ANOVA test. Furthermore, X-ray diffraction (XRD) examination was performed to investigate the crystalline phase of each type of sealer. X-ray fluorescence (XRF) analysis was done for the chemical elemental analysis of each sealer.
RESULTS: The least film thickness, highest alkalinity, and highest calcium ion release were all displayed by AH Plus Bioceramic Sealer. High solubility, high alkalinity, intermediate calcium ion release, and intermediate film thickness were all displayed by Bio-C Sealer. While ADseal root canal sealer displayed the greatest film thickness, least solubility, alkalinity, and calcium ion release.
CONCLUSIONS: Both AH Plus Bioceramic Sealer and Bio-C Sealer represented adequate properties to be considered a good sealer that could be used as a potential alternative to resin-based root canal sealers.
