目的研究常用的9种牙膏在体外对口腔毛滴虫的作用效果,为正确选择牙膏提供一定理论基础。方法通过体外传代培养口腔毛滴虫,以甲苯胺蓝染液为指示测试不同牙膏及相同牙膏不同浓度在体外对口腔毛滴虫的作用效果。结果在浓度分别是3%、5%、7%、9%浓度下不同的牙膏对口腔毛滴虫的致死时间差距很大。结论在体外对口腔毛滴虫杀伤效果最好的是完美夜用装,最差的是冷酸灵去渍亮白。 Objective To study the effects of nine commonly used toothpaste on Trichomonas vaginalis in vitro and to provide a theoretical basis for the correct choice of toothpaste. Methods The oral Trichomonas vaginalis was subcultured in vitro and the effects of different toothpaste and different concentrations of the same toothpaste on Trichomonas phasostris were tested in vitro with toluidine blue stain. Results The differences in the lethal time of different oral dentifrices to Trichomonas vaginalis at the concentrations of 3%, 5%, 7% and 9% were quite different. Conclusion In vitro Trichomonas oral Trichomonas kill the best effect is the perfect night loaded, the worst is cold acid spirit to stain bright.
