摘要： 目的:研究载银纳米二氧化钛(Ag-TiO2)抗菌剂对藻酸盐印模材料抗菌性能的影响,分析其最佳添加比例。方法:常温下将载银纳米TiO2粉末按不同质量分数0~3.5%加入藻酸盐印模中,采用薄膜覆盖法检测藻酸盐印膜材料的抗菌性。结果:分析实验数据可知实验组与对照组比较差异均有统计学意义(均为P<0.05),并且随着Ag-TiO2抗菌剂添加质量比的增高,抗菌率明显增高 ,在抗菌剂质量分数达到2.0%时,藻酸盐印膜材料抗菌率达到99%以上,2.0%为其最佳添加比例。结论:添加Ag-TiO2抗菌剂对藻酸盐印模材料具有抗菌性,且2.0%为抗菌剂的最佳添加质量比。

Abstract: Objective: To study the effect of Ag-embedded nano-TiO2 (Ag - TiO2) antibacterial agent on the antibacterial of alginate impression materials, to analyze the appropriate ratio of the antibacterial agent to the alginate impression material. Methods: The Ag-embedded nano-TiO2 powder were added into the alginate impression materials according to different contents, including 0%, 0.5%, 1%, 1.5%, 2%, 2.5%, 3%, 3.5%,Their antibacterial activities were tested by film adhesion method. Results: Data showed the experimental group had statistically significant difference control group (all P<0.05). The difference increased with Ag-TiO2 antibacterial agent added mass ratio. The antibacterial efficiency was beyond 99% when the adding ratio of antibacterial agent was 2.0% or beyond 20%. Conclusion: Adding Ag-TiO2 antibacterial agent in alginate impression materials had antimicrobial potential, and the best adding ratio of the Ag-TiO2 antibacterial agent was 2.0%.
