添加T-ZnOw对藻酸盐印模材料抗菌性的影响

目的研究添加四针状氧化锌晶须(T-Zn Ow)对藻酸盐印模材料抗菌性的影响。方法向藻酸盐印模材料中加入质量分数为0%、1%、3%、5%、7%、10%的T-Zn Ow,采用薄膜密贴法检测其对白色假丝酵母菌的抗菌效果。结果分析数据可得,实验组与对照组相比均有统计学意义(P<0.05),随着抗菌剂量的增高,抗菌率明显增高,添加抗菌剂质量分数为5%时,抗菌率达99%以上。结论添加T-Zn Ow可增加藻酸盐印模材料的抗菌性,5%为其最佳添加量。

Effect of adding T-ZnOw on the antibacterial property of alginate impression materials

Objective To study the effect of adding Tetrapod?like Zinc Oxide Whisker ( T?ZnOw) on the antibacterial property of al?ginate impression materials. Methods T?ZnOw was added into the alginate impression materials in different proportions, including 0%, 1%, 3%, 5%, 7%, and 10%. The effect of antibacterial properties on Candida albicans was detected by sticking method. Re?sults The experimental group and the control group were statistically significant ( P<0.05) . As the dosage increased, the antibacterial rate increased. When the dosage was as much as 5%, the antibacterial rate was more than 99%. Conclusion Adding T?ZnOw can in?crease the antibacterial property, and 5% is the optimum dosage.
