摘要
目的:比较3种国内纳米级载银无机抗菌剂对口腔病原菌的抗菌活性。方法:采用微量板液体稀释法.测定GKJ-R、Conval PAg-40、TiO2/Ag3种纳米级载银无机抗菌剂对变形链球菌(ATCC25135)、乳酸杆菌(ATCC393)、黏性放线菌(ATCC19246)、牙龈卟啉单胞菌(ATCC33277)的最小杀菌浓度(MBC)。结果:3种纳米级载银无机抗菌剂对变形链球菌、乳酸杆菌、黏性放线菌、牙龈卟啉单胞菌均有良好的杀菌效果,且抗菌能力没有显著区别。结论:为纳米载银无机抗菌剂在牙科抗菌材料领域应用提供理论依据。
AIM：To Compare the antibacterial activity on oral pathogens among three types of nano - silver base inorganic antibacterial agents. METHODS ：The oral pathogens selected were Streptococcus mutans（ ATCC25135 ） , Lactobacillus（ ATCC393 ） ,Actinomyces viscosus （ ATCC19246 ）, Candida Albicans （ ATCC33277 ）. Minimal bactericidal concentration （MBC）was determined by liquid dilution method. RESULTS ： Nano -silver base inorganic antibacterial agents had bactericidal activity against oral pathogens. The general antibacterial activity was nearly equal. CONCLUSION：It is possible that nano- silver base inorganic antibacterial agents can be used in dental antibacterial materials.
