摘要: 目的:研究载银纳米二氧化钛(Nano.Ag-TiO2)对玻璃离子水门汀(glass ionomer cement,GIC)抑菌性的影响。方法:向玻璃离子水门汀中添加质量比为0%、1%、2%、3%、4%、5%的载银纳米二氧化钛,通过机械方法搅拌均匀后,调和并快速填入模具中。观察试件对变形链球菌的抑菌效果和抑菌长效性。结果:随着载银纳米二氧化钛质量分数的增加,对变形链球菌的抑菌率提高了,其较空白组有显著差异(P<0.05);自然老化组的抑菌率没有明显变化。添加载银纳米二氧化钛为3%组的抑菌率达到90%以上。结论:添加载银纳米二氧化钛的玻璃离子具有良好的抗菌性,且抗菌效果持久稳定。

Abstract: Objective: To study the effect of Nano. Ag-TiO2 on the antibacterial property of glass ionomer cements. Methods: Nano.Ag-TiO2 was added into the glass ionomer cement with the mass ratio of 0%, 1%, 2%, 3%, 4% and 5%. After stirred by mechanical means, the mixed cement was filled in the mold quickly. The inhibitory effect and antibacterial durability of specimen were observed on Streptococcus mutans. Results: With the increased content of Nano. Ag-TiO2, the inhibition rate of mixed cement on the Streptococcus mutans raised, which was significant different from the control group (P<0.05); The inhibition rate of the natural aging group did not change significantly. The inhibitory rate of the group with 3% Nano.Ag-TiO2 was more than 90%. Conclusion: Glass ionomer cement added with Nano.Ag-TiO2 has good antibacterial effects with lasting stability.
