Abstract
BACKGROUND: Nano-silver inorganic antimicrobial agent has the characteristics of broad spectrum antimicrobial and antibacterial ability which is one of the hotspots of oral inorganic antibacterial materials research. OBJECTIVE: To study the antibacterial properties and antibacterial mechanism of nano-silver inorganic antimicrobial materials in order to provide reference information for the basic experimental research and the clinical application. METHODS: The antibacterial properties of various oral nano-silver inorganic antimicrobial materials to the common pathogens, such as Streptococcus mutans, Candida albicans and Actinomyces viscosus were analyzed, the antibacterial properties included the minimum bactericidal concentration and antibacterial rate, and the comparative analysis of them was performed. The antibacterial mechanism of nano-silver inorganic antimicrobial materials was researched to clear its advantages and disadvantages. RESULTS AND CONCLUSION: The oral nano-silver inorganic antimicrobial materials had a broad antibacterial spectrum, and had strong antibacterial properties to Streptococcus mutans, Lactobacil us, Actinomyces viscosus, Candida albicans, Porphyromonas gingivalis Aeromonas, Staphylococcus aureus and Escherichia coli. It had the lower minimum bactericidal concentration and the higher antibiotic rate. However, the antibacterial properties of the same nano-silver inorganic antibacterial material for different pathogens were different, showing the different minimum bactericidal concentrations and the different antibacterial rates. On the other hand, different nano-silver inorganic antibacterial materials for the same pathogen had different minimum bactericidal concentrations and different antibacterial rates.关键词
