BACKGROUND
New endodontic sealers are frequently introduced; hence, understanding the properties of each sealer and choosing the most appropriate one is essential for clinical decision-making.
AIM
This study aimed to assess the physicochemical properties of a new zinc oxide eugenol-based sealer (EssenSeal) compared with three other sealers: a calcium hydroxide-based sealer (Hydrosealer), a bioceramic silicone-based sealer (Roeko GuttaFlow), and an epoxy resin-based sealer (AH Plus).
MATERIALS AND METHODS
The evaluation included pH, flow, radiopacity, and solubility according to the ISO 6876/2012 standard. pH levels were measured at various time intervals in deionized water (1, 3, 24, 72, 168, 336, and 504 h). Radiopacity was assessed radiographically in millimeters of aluminum, while solubility was determined after 7 days of immersion in deionized water and quantified by mass loss (%). Data analysis involved ANOVA, Kruskal-Wallis, and pairwise comparison tests, with statistical significance set at < 0.05.
RESULTS
EssenSeal exhibited the highest flow and solubility ( < 0.001), while AH Plus showed the highest radiopacity and the lowest pH and solubility ( < 0.001). Except for AH Plus, all sealers demonstrated alkalinization and radiopacity in compliance with ISO 6876 standards.
CONCLUSION
EssenSeal showed promising physicochemical properties, but did not fully comply with ISO 6876/2012 standards.
背景
新型牙髓封闭剂不断涌现；因此，了解每种封闭剂的性能并选择最合适的封闭剂对于临床决策至关重要。
目的
本研究旨在评估一种新型氧化锌丁香酚基封闭剂（EssenSeal）与其他三种封闭剂的物理化学性能，这三种封闭剂分别是：氢氧化钙基封闭剂（Hydrosealer）、生物陶瓷硅基封闭剂（Roeko GuttaFlow）和环氧树脂基封闭剂（AH Plus）。
材料与方法
根据ISO 6876/2012标准进行评估，包括pH值、流动性、射线不透性和溶解性。在去离子水中不同时间间隔（1、3、24、72、168、336和504小时）测量pH值。通过铝的毫米数进行射线照相评估射线不透性，而在去离子水中浸泡7天后测定溶解性，并通过质量损失（%）进行量化。数据分析采用方差分析、Kruskal-Wallis检验和两两比较检验，统计学显著性设定为<0.05。
结果
EssenSeal表现出最高的流动性和溶解性（<0.001），而AH Plus表现出最高的射线不透性以及最低的pH值和溶解性（<0.001）。除AH Plus外，所有封闭剂均表现出符合ISO 6876标准的碱化和射线不透性。
结论
EssenSeal显示出良好的物理化学性能，但未完全符合ISO 6876/2012标准。
