To evaluate the effect of ethanolic extracts of propolis (EEP) addition in different proportions to glass ionomer cement (GIC) on microleakage and microhardness of GIC.
The cement was divided into four groups: one using the original composition and three with 10%, 25%, and 50% EEP added to the liquid and then manipulated. For microleakage assessment, sixty primary molars were randomly divided into four groups (n=15). Standard Class II cavities were prepared and then filled with EEP in different proportions added to GICs. Microleakage test was performed using a dye penetration method. The data were analyzed using one-way ANOVA and Mann-Whitney U tests (α = 0.05). Disc shaped specimens were prepared from the tested GIC to determine Vickers hardness (VHN). The data were analyzed using one-way ANOVA and post hoc Tukey test (α = 0.05).
There were no statistically significant differences between the groups in terms of microleakage (p > 0.05). There were statistically significant differences between the VHN values of groups (p < 0.05). Increasing addition of EEP to GIC statistically significantly increased VHN value of GIC (p < 0.05).
The addition of EEP to GIC increased the microhardness of the GIC and did not adversely affect the microleakage. Thus, it might be used during routine dental practice due to its antibacterial properties.
评估不同比例的蜂胶乙醇提取物（EEP）添加到玻璃离子水门汀（GIC）中对GIC微渗漏和显微硬度的影响。
将水门汀分为四组：一组使用原始成分，另外三组分别向液体中添加10%、25%和50%的EEP，然后进行调配。为评估微渗漏，将60颗乳牙随机分为四组（n = 15）。制备标准II类洞型，然后用添加了不同比例EEP的GIC进行填充。采用染料渗透法进行微渗漏测试。数据采用单因素方差分析和曼-惠特尼U检验进行分析（α = 0.05）。从测试的GIC制备圆盘状试件以测定维氏硬度（VHN）。数据采用单因素方差分析和事后Tukey检验进行分析（α = 0.05）。
各组之间在微渗漏方面无统计学显著差异（p > 0.05）。各组的VHN值之间存在统计学显著差异（p < 0.05）。向GIC中增加EEP的添加量可使GIC的VHN值有统计学显著增加（p < 0.05）。
向GIC中添加EEP可提高GIC的显微硬度，且不会对微渗漏产生不利影响。因此，因其抗菌特性，它可能可用于常规牙科治疗。
