The purpose of this investigation was to compare the compressive and diametral tensile strengths of two silver-reinforced and three conventional glass-ionomer cements of different powder-to-liquid ratios at 1 and 24 hours. ANOVA (P < 0.001) and Tukey's Studentized Multiple Range Test indicated significant differences between the compressive strengths of several of the cements tested (P < 0.05). No significant differences were noted between any of the cements for the diametral tensile strength test (alpha = 0.05).
本研究的目的是比较两种银增强型和三种不同粉液比的传统玻璃离子水门汀在1小时和24小时时的抗压强度和径向拉伸强度。方差分析（P < 0.001）和Tukey氏学生化多重极差检验表明，几种受试水门汀的抗压强度之间存在显著差异（P < 0.05）。在径向拉伸强度试验中，任何一种水门汀之间均未观察到显著差异（α = 0.05）。
