This study aims to evaluate the physicochemical properties of a new experimental alginic acid-incorporated bioceramic-based sealer (Bio-G) compared to commercialized BioRoot RCS.
Bio-G sealers with 0%, 3%, and 5% alginic acid concentrations were formulated and tested for flowability, film thickness, radiopacity, working time, setting time, solubility, dimensional stability, and pH. Standardized methodological methods were used and statistical analysis was performed using the one-way ANOVA with post hoc Tukey's HSD.
All Bio-G sealer groups met standards for flow (>20 mm) and film thickness (<50 μm). Bio-G (0%-algin) exhibited the highest flow, solubility, and longest setting time, while Bio-G (3%-algin) and Bio-G (5%-algin) had comparable solubility with BioRoot RCS. Radiopacity was lower in all Bio-G sealers than in BioRoot RCS but exceeded the required minimum standard. Moreover, all Bio-G sealer groups maintained an alkaline pH.
The incorporation of alginic acid influenced the physicochemical properties of Bio-G sealers, supporting their potential as alternative bioceramic materials for endodontic applications.
本研究旨在评估一种新型实验性含藻酸生物陶瓷基封闭剂（Bio - G）与商业化的BioRoot RCS相比的物理化学性质。
配制了藻酸浓度为0%、3%和5%的Bio - G封闭剂，并对其流动性、膜厚度、射线不透性、工作时间、凝固时间、溶解度、尺寸稳定性和pH值进行了测试。采用标准化方法，并使用单因素方差分析和事后Tukey's HSD进行统计分析。
所有Bio - G封闭剂组均符合流动性（>20 mm）和膜厚度（<50μm）标准。Bio - G（0%-藻酸）表现出最高的流动性、溶解度和最长的凝固时间，而Bio - G（3%-藻酸）和Bio - G（5%-藻酸）与BioRoot RCS具有相当的溶解度。所有Bio - G封闭剂的射线不透性均低于BioRoot RCS，但超过了所需的最低标准。此外，所有Bio - G封闭剂组均保持碱性pH值。
藻酸的加入影响了Bio - G封闭剂的物理化学性质，支持了它们作为牙髓治疗应用中替代生物陶瓷材料的潜力。
