摘　　要：目的对氟保护漆与含氟自酸蚀光固化粘结剂(自酸蚀处理剂内含活性氟离子)抑制脱矿进行临床比较。方法分别用氟保护漆和含氟自酸蚀光固化粘结剂2种方式处理牙面,应用DIAGNOdent龋齿检测仪测量釉质表面,对比分析前后仪器读数的变化反映釉质脱矿的情况。结果含氟自酸蚀光固化粘结剂较氟保护漆预防脱矿的效果在1个月时更加显著,在3个月时两者之间无显著性差异。结论短期内,含氟自酸蚀光固化粘结剂优于氟保护漆,它可用于预防正畸治疗过程中早期釉质脱矿。Objective To compare the effects of fluor protector and visible fluoride-releasing self-etching light-activated bonding system on inhibition of enamel decalcification.Methods The enamel was treated with the two agents respectively.After treatment,the enamel surfaces of all samples were detected by DIAGNOdent.The effect of each agent on enamel remineralization was analyzed by paired-sample t test.Results This study showed that visible fluoride-releasing self-etching light-activated bonding system was more effective than fluor protector on inhibition of enamel decalcification 1 month after appliance.No significant difference was found between the two systems 3 month later.Conclusions The visible fluoride-releasing self-etching light-activated bonding system has better remineralization effect.It can be used to inhibit enamel decalcification in early period during orthodontic treatment.
