不同浓度氟化泡沫对牙釉质再矿化影响的对比研究

目的 探讨不同浓度的氟化泡沫对人离体牙牙釉质再矿化的影响.方法 在人牙釉质标本上形成早期龋后随机分组,分别涂布0.60%、0.92%、1.23%氟化泡沫和蒸馏水.用激光荧光诊断仪对人工龋损进行定量诊断检查.结果 在使用不同浓度的氟化泡沫实验组与对照组之间,对减少牙釉质脱矿作用,增强牙釉质的再矿化具有显著性差异(P＜0.01),而前磨牙同一条件下0.6%氟化泡沫与0.9%氟化泡沫对对减少牙釉质脱矿作用,增强牙釉质的再矿化作用相比较无显著性差异(P＞0.05).结论 由于0.60%氟化泡沫与0.92的氟化泡沫对牙釉质的再矿化影响比较接近,以选择0.60%的氟化泡沫进行牙病群体防治较为安全.

Comparative studies of remineralization effects of fluoridated foam with different concentration on human enamal of teeth

Objective To investigate the effects of fluoridated foam with 3 different concentration on remineralization of the human enamal of teeth.Methods Human enamal specimens who were demineralized were divided into groups randomly.Samples were treated with 0.60%,0.92%,1.23% fluoride foam and distilled water respectively.Made a quantitative diagnosis of the artificial caries with a laser fluorescence system.Results The results showed significant differences in reducing the decalcification with boosting up the remineralization from the enamel of teeth between the experiment team and antitheses team with different concentration of fluoride foam(P<0.01).But the results showed no significant differences in reducing the decalcification with boosting up the remineralization from the enamel of teeth between premolar teeth with 0.60% fluoride foam and premolar teeth with 0.92% fluoride foam(P>0.05).Conclusion On account of the effect of 0.60% fluoride foam and 0.92% fluoride foam on the acid resistance of enamel of teeth is close,so we can take safety of usingin fluorine into account to select 0.60% fluoride foam to increase the safety at employment caries of prevention and cure in colony for the future.
