Physicochemical properties of pozzolan Portland cement were compared to ProRoot MTA and MTA BIO. To test the pH, the samples were immersed in distilled water for different periods of time. After the pH analysis, the sample was retained in the plastic recipient, and the electrical conductivity of the solution was measured. The solubility and radiopacity properties were evaluated according to specification 57 of the American National Standard Institute/American Dental Association (ANSI/ADA). The statistical analyses were performed using ANOVA and Tukey's test at a 5% level of significance. Pozzolan Portland cement exhibited pH and electrical conductivity mean values similar to those of the MTA-based cements. The solubilities of all tested materials were in accordance with the ANSI/ADA standards. Only the MTA-based cements met the ANSI/ADA recommendations for radiopacity. It might be concluded that the pH and electrical conductivity of pozzolan Portland cement are similar to and comparable to those of MTA-based cements.
将火山灰硅酸盐水泥的物理化学性质与ProRoot MTA和MTA BIO进行了比较。为了测试pH值，将样品在蒸馏水中浸泡不同时间。pH分析后，将样品保留在塑料容器中，并测量溶液的电导率。根据美国国家标准学会/美国牙科协会（ANSI/ADA）的规范57评估溶解性和不透射线性。使用方差分析和Tukey检验进行统计分析，显著性水平为5%。火山灰硅酸盐水泥的pH值和电导率平均值与基于MTA的水泥相似。所有测试材料的溶解性均符合ANSI/ADA标准。只有基于MTA的水泥符合ANSI/ADA关于不透射线性的建议。可以得出结论，火山灰硅酸盐水泥的pH值和电导率与基于MTA的水泥相似且具有可比性。
