With the purpose of preparing an anti-bacterial adhesion dental resin, two silicone methacrylates (SMAs) were synthesized. After being confirmed by the FT-IR and ¹H-NMR spectra, the SMAs were incorporated into commonly used Bis-GMA/TEGDMA (50/50, wt./wt.) dental resin systems with an incremental series of concentrations. Physicochemical properties, anti-bacterial adhesion effect, and protein adsorption were tested. The results showed that SMAs had no influence on the double bond conversion of dental resin, and could decrease volumetric shrinkage of dental resin. Because of the increased hydrophobicity and reduced surface free energy, SMAs containing cured resin had resistance to mucin adsorption and anti-adhesion effect against S. mutans. However, flexural properties, water sorption and solubility of dental resin were impaired after introducing SMAs. Therefore, further research should be undertaken to improve these properties by utilizing appropriate inorganic fillers.

为了制备一种抗菌粘附牙科树脂，合成了两种甲基丙烯酸硅树脂 (SMA)。在通过 FT-IR 和¹ H-NMR 光谱确认后，SMA 被纳入常用的 Bis-GMA/TEGDMA（50/50，wt./wt.）牙科树脂系统，并具有一系列递增的浓度。测试了理化性质、抗菌粘附作用和蛋白质吸附。结果表明，SMAs对牙科树脂的双键转化没有影响，可以降低牙科树脂的体积收缩率。由于疏水性增加和表面自由能降低，含有固化树脂的SMA具有抗粘蛋白吸附和对变形链球菌的抗粘附作用. 然而，在引入 SMA 后，牙科树脂的弯曲性能、吸水性和溶解性受到损害。因此，应进一步研究通过使用适当的无机填料来改善这些性能。
