本研究的目的是评估浸泡在酒精饮料中的复合树脂的显微硬度和表面粗糙度。使用三种复合树脂：Durafill (Heraeus Kulzer)、Z250 (3M-ESPE) 和 Z350 XT (3M-ESPE)。测量初始表面粗糙度和显微硬度。样本分为四组（n=30）：G1-人工唾液； G2-啤酒； G3-伏特加； G4-威士忌。将样品浸入饮料中，每天 3 次，持续 15 分钟，持续 30 天。浸泡期后重复表面粗糙度和显微硬度测定。通过双向ANOVA和Tukey-HSD检验对数据进行统计分析（p
The aim of this study was to evaluate the microhardness and surface roughness of composite resins immersed in alcoholic beverages. Three composite resins were used: Durafill (Heraeus Kulzer), Z250 (3M-ESPE) and Z350 XT (3M-ESPE). The inital surface roughness and microhardness were measured. The samples were divided into four groups (n=30): G1-artificial saliva; G2-beer; G3-vodka; G4-whisky. The samples were immersed in the beverages 3x a day for 15 min and 30 days. The surface roughness and microhardness assays were repeated after immersion period. The data were statistically analyzed by two-way ANOVA and Tukey-HSD test (p
