主 题：Dental resin composites silicone hydrophobicity anti-biofilm physicochemical property
摘 要：Novel branched silicone methacrylate was *** mechanical and biological properties of the resin system were investigated to select the formula proportion with the best overall *** novel silicone-containing monomers were combined with an incremental sequence of glass filler concentrations in commonly used Bis-GMA/TEGDMA(50/50,wt./wt.)dental resin *** properties,surface properties,antibacterial adhesion effect,anti-biofilm effect,protein adsorption,and cytotoxicity were *** results showed that BSMs did not affect the double bond conversion of dental resin,but could reduce volumetric shrinkage(p0.05).The BSM containing resins can resist protein and bacteria adhesion(***)because it has increased hydrophobicity and a lower free energy surface(p0.05).However,there were no statistically significant differences in cytotoxicity,surface roughness,and double bond conversion ***,the results indicate that changes in a material’s properties are not strictly proportional to its *** silicone resin methacrylate can reduce the polymerization shrinkage,have low surface energy and anti-adhesion *** composite resin containing 70%matrix has the best comprehensive *** silicone methacrylate composite represents an innovative method to improve the properties and reducing secondary caries.
