| 摘 要： | 目的观察2种不同浓度的氟制剂对牙釉质表面显微硬度值的影响。方法将牙釉质块随机分为A、B 2组,脱矿30 min后在2组牙釉质表面分别涂布0.9%中性氟化钠溶液和1.0%氟化食醋3 min,并在人工唾液中浸泡30 min,24 h后测定牙釉质表面显微硬度值。结果 2组氟制剂涂布后牙釉质表面显微硬度值均有显著提高,涂布1.0%氟化食醋组的牙釉质表面显微硬度值高于0.9%中性氟化钠溶液组,统计学分析人工唾液浸30 min时差异有统计学意义,24 h差异无统计学意义。结论 2种不同浓度的氟制剂均可使牙釉质表面显微硬度显著提高,1.0%氟化食醋效果优于0.9%中性氟化钠溶液。

| Abstract: | Objective To investigate the influence of two different concentration fluoride agents on microhardness of enamel surface. Methods Demineralized enamel blocks, randomly divided into two groups, were varnished by 0.9%neutral fluorid sodium and 1.0% fluoride vinegar for 3 min. After being immersed for 30 min and 24 h in artificial salivary, the microhardness data of enamel blocks were tested by M-style microhardness meter. Results After varnished by two fluoride agents, surface microhardness of two-group demineralized enamel blocks was improved. Enamel surface microhardness dealed with fluoride vinegar was higher than that dealed with 0.9%meutral fluoride sodium at 30 min （P〈0.05）, for 24 h （P〉0.05）. Conclusion Both different concentration fluoride agents can improve microhardness of enamel surface,the influence of 1.0% fluoride vinegar on microhardness of enamel surface is superior to that of 0.9% neutral fluoride sodium. |
