The aim of the present study was to compare the physico-chemical properties of EssenSeal with AH PLUS bioceramic and Pulp Canal Sealer EWT. Flow, solubility, film thickness, radiopacity and setting time were evaluated according to ISO 6876 (2012) specifications. External and cross-section surface characteristics were analysed under a scanning electron microscope. Statistical analysis was performed using Shapiro-Wilk's test, one-way ANOVA and the Tukey HSD test. All the sealers conformed to the ISO 6876 (2012) standards, except for the setting time for AH plus bioceramic, which exceeded more than 10% of the time indicated by the manufacturer. Statistically significant differences were found between the three study sealers regarding the physico-chemical properties tested (p < 0.05). EssenSeal demonstrated characteristics respecting the ISO 6876 (2012) standards and can be considered a predictable alternative in root canal sealing.
本研究旨在比较 EssenSeal 与 AH PLUS 生物陶瓷和 Pulp Canal Sealer EWT 的理化性能。根据 ISO 6876（2012）规范评估了流动性、溶解度、膜厚度、射线不透性和凝固时间。使用扫描电子显微镜分析了外部和横截面表面特性。使用 Shapiro-Wilk 检验、单因素方差分析和 Tukey HSD 检验进行统计分析。所有密封剂均符合 ISO 6876（2012）标准，除了 AH plus 生物陶瓷的凝固时间超过制造商规定时间的 10%。在所测试的理化性能方面，三种研究用密封剂之间存在统计学显著差异（p<0.05）。EssenSeal 表现出符合 ISO 6876（2012）标准的特性，可被视为根管密封的一种可预测的替代选择。
