| 摘 要： | 目的:研究含氟牙膏对脱矿离体恒牙釉质的再矿化作用。方法:选取24颗牙齿硬度在285 kg/mm2左右的脱矿离体牛恒牙,随机分为A、B、C 3组。A组用含氟的纳爱斯营养维C牙膏处理,B组用不含氟的纳爱斯鲜浓果味牙膏处理,C组不作任何处理,同时将3组标本用人工唾液涂抹。然后用自动转塔数显显微维氏硬度计测定每颗牙齿硬度并记录。结果:A组脱矿后恒牙硬度平均值285.2±4.3与再矿化后牙齿硬度平均值356.9±7.9比较,有统计学差异(P<0.05);B组脱矿恒牙的硬度平均值284±5.2与再矿化后牙齿硬度平均值302.3±3.8比较无统计学差异(P>0.05);C组脱矿恒牙的硬度平均值285.3±5.1与再矿化后牙齿硬度平均值272.0±6.6比较无统计学差异(P>0.05)。再矿化后A组牙齿硬度平均值显著高于B、C两组(P<0.05)。结论:含氟牙膏能有效促进脱矿离体恒牙釉质的再矿化。

| Abstract: | Objective: To explore the effect of fluoride toothpaste on enamel re-mineralization of extracted permanent teeth.Methods: Twenty-four enamel specimens of bovine intact permanent teeth were selected based on the hardness data of about 285 kg/mm2 and were randomly divided into group A,B and C.Group A was treated with fluoride toothpaste,group B was treated with non-fluoride toothpaste,while group C was selected as the control group with non-treatment.All specimens were smeared with artificial saliva.The ename... |
