To assess if incorporating ethanolic extract of propolis into ceramic-reinforced glass ionomer (Amalgomer CR) might have an influence on its physicomechanical properties.
Three groups were assessed; group I: Amalgomer CR (control) and two experimental groups (II and III) of propolis added to the liquid of Amalgomer CR with 25 and 50 v/v %, respectively. Evaluation parameters were color stability, compressive strength, microhardness, and surface roughness. Representative specimens of each group were analyzed by Fourier-transform infrared spectroscopy, energy-dispersive X-ray, X-ray diffraction, and scanning electron microscopy. Analysis of variance (ANOVA) was used to compare the results, followed by a Tukey post hoc test ( < 0.05).
Nonsignificant color change for both groups of modified Amalgomer CR. Meanwhile, the two experimental groups exhibited a significant increase in both compressive strength and microhardness. Simultaneously, there was a significant difference in roughness values among groups with the lowest roughness values exhibited by the 50 v/v % propolis concentration.
Modification of Amalgomer CR with 50 v/v % propolis may increase its mechanical properties without compromising its esthetic. . Modification of Amalgomer CR by 50 v/v % propolis is supposed to be a hopeful restorative material with favorable characteristics.
评估将蜂胶乙醇提取物添加到陶瓷增强玻璃离子水门汀（Amalgomer CR）中是否会对其物理机械性能产生影响。
评估三组；第一组：Amalgomer CR（对照组），以及两个实验组（第二组和第三组），分别将25%和50%（v/v）的蜂胶添加到Amalgomer CR的液体中。评估参数包括颜色稳定性、抗压强度、显微硬度和表面粗糙度。通过傅里叶变换红外光谱、能量色散X射线、X射线衍射和扫描电子显微镜对每组的代表性标本进行分析。采用方差分析（ANOVA）比较结果，随后进行Tukey事后检验（P<0.05）。
两组改性Amalgomer CR的颜色变化均不显著。同时，两个实验组的抗压强度和显微硬度均显著增加。同时，各组之间的粗糙度值存在显著差异，50%（v/v）蜂胶浓度组的粗糙度值最低。
用50%（v/v）蜂胶改性Amalgomer CR可提高其机械性能，同时不影响其美观性。用50%（v/v）蜂胶改性Amalgomer CR有望成为一种具有良好特性的修复材料。
