The aim is to investigate the effect of resveratrol on micro-shear bond strength (µSBS) of adhesive to enamel after 40% hydrogen peroxide application. For µSBS test, 50 teeth were obtained, 2/3 of crowns were embedded into acrylic resin. After application of hydrogen peroxide twice, teeth were randomly allocated to control group and 9 groups (n = 15) according to concentrations (0.5, 1, 2 µM) and application periods (10, 30, 60 min) of resveratrol. Following, composite resin was placed onto enamel surfaces using 3 tygon tubes for each tooth. µSBS test was performed and failure modes were displayed. To analyze µSBS values, Kruskal Wallis and Mann-Whitney U tests were performed. µSBS values of 1 µM resveratrol for 10 min applied group were statistically higher than control group (p < 0.05). 1 µM resveratrol showed higher µSBS values than 0.5 µM and 2 µM (p < 0.05). No significant difference was detected between application periods (p > 0.05). The improvement of µSBS values with 1 µM resveratrol application may be promising for clinical problems related to reduced bond strength after bleaching.
目的在于研究白藜芦醇对经 40%过氧化氢处理后的牙釉质微剪切粘结强度（µSBS）的影响。为进行 µSBS 测试，获得 50 颗牙齿，牙冠的 2/3 嵌入丙烯酸树脂中。经两次过氧化氢处理后，根据白藜芦醇浓度（0.5、1、2 µM）和应用时间（10、30、60 分钟），将牙齿随机分配至对照组和 9 个实验组（n = 15）。随后，使用 3 个 tygon 管将复合树脂置于牙釉质表面。进行 µSBS 测试并显示失效模式。为分析 µSBS 值，进行了 Kruskal Wallis 和 Mann-Whitney U 检验。应用 10 分钟、浓度为 1 µM 的白藜芦醇的实验组 µSBS 值明显高于对照组（p < 0.05）。1 µM 白藜芦醇的 µSBS 值高于 0.5 µM 和 2 µM（p < 0.05）。各应用时间之间无显著差异（p > 0.05）。应用 1 µM 白藜芦醇可提高 µSBS 值，这对于解决与漂白后粘结强度降低相关的临床问题可能具有前景。
