摘　　要：选取80例中重度氟斑牙需要正畸的患者,随机分成4组,采用不同方式粘接托槽,比较其托槽脱落率。京津釉质粘合剂组、光固化直接粘接组、釉质局部磨除组、牙齿表面贴面组的托槽总脱落率分别为54.26%、17.38%、2.47%、1.36%。结果表明光固化复合树脂优于京津釉质粘合剂,釉质局部磨除法和牙齿表面贴面法的疗效明显优于其他方法。80 patients with moderate and severe fluorotic teeth underwent orthodontic treatment,the patients were randomly divided into 4 groups.The brackets were bonded by Jingjin enamel adhesive（group A）,light-curing composite resin（group B）,removal of enamel surface followed by light-curing composite resin bonding（group C） and resin laminate veneers （group D） respectively.The brackets loss rate was observed for 12 weeks.The brackets loss rate of group A,B,C and D was 54.26％,17.38％,2.47％ and 1.36％ respectively.Removal a small amount of surface enamel and light-cured veneer may produce better adhesive effect of bracket on fluorotic teeth.
