| 摘 要： | 目的研究没食子对牙釉质的矿化作用,探讨没食子防龋的临床价值。方法应用离体牛牙制备人工釉质龋标本120颗,随机分为脱矿组和再矿化组各60颗,每组再分为氟化钠组、没食子组、去离子水组各20颗,分别进行脱矿和再矿化实验,行光敏荧光技术及扫描电镜检查,比较各组脱矿后及再矿化后荧光量及扫描电镜结果。结果荧光结果显示,在脱矿及再矿化实验中,没食子组和氟化钠组药物作用前后荧光量的比值比较差异无统计学意义(P>0.05),与去离子水组比较差异均有统计学意义(P<0.05);扫描电镜显示,没食子组和氟化钠组牙面均有颗粒附着,效果接近,去离子水组牙面无颗粒附着。结论没食子对离体牙釉质有再矿化、抗酸脱矿作用,对预防龋病发生有一定作用。

| Abstract: | Objective To study the effect of clinical value of Aleppo gall on preventing dental caries based on experimental observation of bovine enamel in vitro.Methods A total of 120 extracted bovine anterior teeth were prepared and randomly divided into two groups with 60 teeth in each group for demineralization and remineralization experiments.Each group was randomly redivided into three groups with 20 teeth in each group and treated with fluoride,Aleppo gall and deionized water respectively.And these three groups... |
