Abstract:

BACKGROUND: Silver-carrying antibacterial agent has become a research hotspot in inorganic antibacterial agents for oral cavity, because of high biosafety, super antibacterial activity and no drug toletance.
OBJECTIVE: To summarize the structure and silver-carrying principle of some common anti-bacterial agent as well as their modification way (silver-carrying approach, silver-carrying environment) on the anti-bacterial effect, improving the defects of raw materials.
METHODS: A computer-based online search of CNKI and OVID database from 2000 to 2010 was performed for articles about the silver-carrying anti-bacterial agents and their carriers.
RESULTS AND CONCLUSION: No matter traditional zeolite, phosphate and other carriers, or new nano-silver, people are continuously modifying the self characteristics and silver-carrying of the materials so as to obtain a silver-carrying antibacterial agent, through the modification, we hope that the dosage can be reduced and the antibacterial activity can be increased beside their shortage. The expectant silver-carrying antibacterial agent can not only depend on the nanotechnology, but also the combine material, sustained-release and becoming an accessory.
