摘要
目的:以单质银作为抗菌剂,采用真空等离子法喷涂羟基磷灰石涂层,研究其对变形链球菌的抗菌性能。方法:采用真空等离子喷涂技术,在钛基材表面制备含银颗粒的羟基磷灰石涂层材料。按添加银粉的重量百分比,分为HA0组(0%)、HA1组(1%)、HA3组(3%)和HA5组(5%)。采用薄膜密着法检测抗菌剂对变形链球菌的抑菌作用,并分析比较抗菌剂添加比例与抗菌性能的相关性。结果:采用真空喷涂法,当单质银重量百分比>3%时,试验样品有抑菌作用。结论:采用单质银作为抗菌剂,进行钛表面真空喷涂,该涂层对变形链球菌有杀菌作用。
PURPOSE： To study the antibacterial activity of plasma sprayed silver-containing hydroxyapative （HA） coatings. METHODS： Silver-containing HA coatings were prepared on titanium substrated by vacuum plasma spraying （VPS）. The samples were divided into 4 groups according to weight percent of the antimierobiah group HA0 （0%）,group HA1 （1%）,group HA3 （3%） and group HA5 （5%）. The antimicrobial properties against Streptococcus mutans were assayed with the pelliele-stieking method. RESULTS： When the weight percent of the silver was 〉3%, the silver-containing HA coatings exhibited significant anti-bacterial effects against Streptococcus mutans. CONCLUSION： The silver-containing HA coating has good inhibitory effect on Streptococcus mutans.
