[摘要]目的：探讨氟保护漆在正畸治疗中对釉质脱矿的抑制效果。方法：研究分两组，实验组在粘结托槽时，酸蚀后均匀地涂一薄层氟保护漆，30s后用粘合树脂粘结托槽。对照组粘结托槽时未做其他处理。矫治6个月后，观察两组釉质脱矿情况。结果：实验组的釉质脱矿率明显比对照组低。结论：氟保护漆对正畸治疗中的釉质脱矿有明显抑制作用。

    Abstract: Objective Discussion fluoride vanish in the orthodontic treatment on enamel demineralization inhibitory effect. Methods Study divided into two groups,experimental group in the bonded bracket, the after etching a thin layer evenly coated fluoride vanish,30 seconds after using adhesive resin bonded brackets.The control group when bonded brackets without making other treatment. Then 6 months after treatment to observe the situation of two groups of enamel demineralization. Results Experimental group of enamel demineralization was significantly lower than the control group. Conclusion The fluoride-vanish on the orthodontic treatment of enamel demineralization has significant inhibitory effect. ......
