这篇研究的目的是为了制备和呈现一种全新的采用聚亚己基双胍(PHMB)进行改良并符合ISO 6876:2001标准的根管封闭剂,并评估其物理和抗菌特性。

改良的封闭剂是将适量的氧化锌与含有不同浓度PHMB (0.05, 0.1, 0.2, 0.4, 0.6 and 0.8%)的丁香酚按照1:1的比例进行混合而成(w/v)。材料固化后评估其固化时间、流动性、膜厚、溶解度和3维变化。结果表明,改良的封闭剂其物体特性符合ISO 6876:2001标准。采用改良直接接触试验(DCT)评估其抗粪肠球菌的抗菌活性。结果显示,当PHMB浓度为0.05, 0.1和0.2%时,改良根管封闭剂的物理和抗菌活性最佳。
