摘要
目的:测定氟保护漆与氟化泡沫应用前、后乳牙釉质中氟的含量变化。方法:选择30例患者,以临床同一患者将要拔除的一对下颌乳中切牙为研究对象,随机将患者分为a、b2组,a组为:1颗牙拔除作为对照,另1颗涂布氟保护漆,24h后再拔除;b组为:1颗拔除作为对照,另1颗涂布氟化泡沫4min,24h后拔除。采用中子活化法测定a、b组每颗牙釉质中氟的含量,进行统计学分析。结果:a组:实验组氟化物的含量为(142.78±42.25)μg/g,对照组为(119.62±38.62)μg/g。b组:实验组釉质中氟含量为(162.36±31.36)μg/g,对照组为(126.56±38.42)μg/g;实验组中氟的含量均大于对照组(P<0.05)。结论:氟保护漆、氟化泡沫的临床应用均能有效增加牙齿釉质中氟的含量。
Objective：To determine the fluorine content in enamel before and after besmearing fluoride varnishes or fluorinated bubbles. Methods：Thirty patients whose deciduous central incisors will be extracted were divided into group a and b randomly. For the same patient, a pair of mandibular deciduous central incisor were chosen, For group a： one tooth was removed, and the other one besmeared with fluoride varnishes and removed 24 h later, For group b： one tooth was removed, and the other one besmeared with fluorinated bubbles and removed 24 h later. The fluorine contents in the enamel of every tooth were determined by neutron activation method and analyzed statistically. Results：For group a： the fluorine content in the experimental group was （ 142.78 ±42.25） ug/g, and that in the control group was （ 119.62 ±38.62 ） ug/g. For group b ： （ 162.36 ± 31.36） ug/g and （ 126.56 ± 38.42 ）ug/g respectively. The fluorine content in the enamel of tooth besmeared with fluoride varnishes or fluorinated bubbles was higher than that in the control group（P 〈0.05 ）. Conclusion：The application of fluoride varnishes and fluorinated bubbles can effectively increase the content of fluorine in the scierous tissues of tooth.
