本研究通过对150名儿童恒牙5年的临床试验结果表明,氟离子导入法的防龋效果明显优于涂氟法(P<0.01)。牙釉质氟含量测定与釉质表面的扫描电镜观察结果亦表明,氟离子导入法的釉质氟含量明显高于涂氟法(P<0.01),且二者的釉质表面形貌结构有较大的差异。
In this study, the results of clinical trials of 150 children with permanent teeth for 5 years showed that the fluoride ion introduction method was superior to fluoride fluoride method (P <0.01). Enamel fluoride content and enamel surface scanning electron microscopy observations also showed that fluoride ion introduction of enamel fluoride content was significantly higher than the fluorine coating method (P <0.01), and the two enamel surface topography has a greater difference .
