LZB-GC纳米载银抗菌剂在藻酸盐印模材料中的抗菌性
Antibacterial properties of LZB-GC nano-silver-filled antibacterial agents used in alginate impression materials
摘要
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%.关键词
