摘　　要：目的:使用激光荧光法对奥威尔牙齿脱敏剂对牙本质早期龋再矿化及抑制脱矿的作用进行评价。方法:对60颗离体牙标本建立人工龋模型后,随机分为3组,分别使用奥威尔凝胶、含氟牙膏和蒸馏水处理1h后酸蚀24h,以激光荧光诊断仪记录各时点的荧光读数。采用t检验和ANOVA方差分析进行统计分析。结果:奥威尔组和含氟牙膏组再矿化前后荧光读数有显著性差异,奥威尔组的读数显著低于含氟牙膏组。与空白对照组相比,奥威尔组和含氟牙膏组酸蚀后的读数均显著较低,但2组之间无统计学差异。结论:奥威尔凝胶具有再矿化和抑制脱矿作用,其再矿化作用优于普通含氟牙膏,而抑制脱矿作用与普通含氟牙膏相当。Objective：To evaluate the effect of Oravive on remineralization and anti-demineralization ability with a laser fluorescence system.Methods：60 premolar specimens with artificial caries lesion were divided into three groups randomly.Samples were treated with Oravive,fluoride dentifrice and distilled water for 1 h,then etched for 24 h.A laser fluorescence system was used to make a quantitative record.Results：Oravive showed a statistically significant effect on remineralization and anti-demineralization ability.There was significant difference between Oravive and fluoride dentifrice on remineralization,but no difference on anti-demineralization.Conclusion：Oravive has good remineralization and anti-demineralization effects.Oravive is better than fluoride dentifrice on remineralization but equivalent to it on anti-demineralization.
