【摘要】 目的　纳米材料是近年发展起来的一种新型高性能材料 ;KHFS—ZN纳米抗菌剂具有广谱、长效、低毒等特点。研究其与丁香酚混合形成凝固体后的抑菌性能。方法　应用琼脂扩散法 ,以大肠杆菌 (Escherichiacoli)AS1 90为试验菌种 ,测试该纳米抗菌剂丁香酚粘固粉的抑菌范围 ,并与普通氧化锌丁香油粘固粉比较。结果　KHFS—ZN纳米抗菌剂和普通氧化锌丁香油粘固粉均有抗菌作用 ,但用 75 %酒精及蒸馏水洗涤后 ,仅前者有抑菌作用。结论　KHFS—ZN纳米抗菌剂与丁香酚混合后 ,其纳米分散体系没有被破坏 ,仍有抑菌性能。可选作牙齿根管充填剂更多还原

【Abstract】 Objective To study the range of bacteriostastic of KHFS-ZN nanomateria eugenol cement.Methods Escherichia coli AS1.90 was chosen as the experiment bacterium;and the effects of KHFS-ZN nanomaterial eugenol cement And Zinc oxide eugenol cement were observed.Results KHFS-ZN nanomaterial eugenol cement still inhibited growth of escherichia coli after washed by 75% alcohol and distiled water.Conclusions KHFS-ZN nanomaterial eugenol cement has lasting bacteriogtastic and can be used for tooth canal filling.更多还原
