摘要:

背景:关于藻酸盐印模材料的消毒方法一直存在争议。
目的:分析LZB-GC纳米载银抗菌剂在藻酸盐印模材料中的最佳添加比例。
方法:将LZB-GC抗菌剂分别以0.125%,0.25%,0.5%,1%,1.5%,2%,2.5%的比例添加到藻酸盐印模材料中,以未添加LZB-GC抗菌剂的藻酸盐印模材料为对照,采用薄膜密着法测试其对金黄色葡萄球菌和大肠杆菌的抗菌性能。
结果与结论:随着LZB-GC抗菌剂添加量的增加,对金黄色葡萄球菌和大肠杆菌的抗菌率随之增大(P < 0.05),当添加量达到0.5%及以上,抗菌率可达到99%以上。说明LZB-GC抗菌剂在藻酸盐印模材料中的最佳添加比例为0.5%。

Abstract:

BACKGROUND: The disinfection method of alginates impression materials has been controversial.   
OBJECTIVE: To analyze the appropriate ratio of the LZB-GC nano-silver-filled antibacterial agent to the alginate impression material.
METHODS: The LZB-GC antibacterial agents were added into the alginate impression materials according to different contents, including 0.125, 0.25%, 0.5%, 1%, 1.5%, 2% and 2.5%. The alginate impression materials without the LZB-GC antibacterial agents served as a control. Their antibacterial activities were tested by film adhesion method, including Staphylococcus aureus and Escherichia coli.
RESULTS AND CONCLUSION: The antibacterial efficiency was increased as the adding ratios of antibacterial agent against two tested bacteria strains increased (P < 0.05). The antibacterial efficiency was beyond 99% when the adding ratio of antibacterial agent was 0.5% or beyond 0.5%. It was indicated that the best adding ratio of the LZB-GC antibacterial agent in the alginate impression material was 0.5%.
