添加T-ZnOw对藻酸盐印模材料抗菌性的影响

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

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。

Objective To study the effect of adding Tetrapod-like Zinc Oxide Whisker （T-ZnOw） on the antibacterial property of alginate 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. Resuits 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.
