[摘要]目的：探讨采用含氟树脂封闭剂封闭预防正畸治疗过程釉质脱矿的可行性。方法：选取临床正畸患者30例，共542颗需粘结的牙齿，采用自身对照的方法分为实验组(共274颗牙齿)和对照组(共268颗牙齿)，实验组先采用含氟树脂封闭剂封闭，然后用临床常规材料粘结托槽，对照组采用临床常用粘结剂。观察两组牙齿的托槽脱落率以及釉质脱矿情况。结果：两组牙齿托槽脱落率无显著性差异，实验组的抗釉质脱矿能力高于对照组。结论：用含氟树脂封闭剂封闭牙面预防釉质脱矿具有临床可行性，值得推广应用。

Abstract: Objective To determine the feasibility of prevention of enamel decalcification with fluoride-releasing resin sealant. MethodsA total of 542 teeth were chosen in 30 patients who needed fixed appliance for orthodontic treatment. The patients were divided into study group (with 274 teeth) and control group (with 268 teeht) by self-control study. The teeth in control group were sealed with fluoride-releasing resin sealant and then bonded with brackets by adhesives commonly used in clinical,the teeth in control group just bonded with brackets by adhesives commonly used in clinical as control group. Observe the failure rates of brackets bonded and dental decalcification was done respectively in the to groups in 12 months after the treatment,the results were analyzed with statistics.ResultsThe failure rates of brackets bonded were no significant difference between two groups,and the resistance of enamel decalcification was significantly higher in control group.ConclusionEnamel sealed with fluoride-releasing resin sealant may be an effective method to prevent the enamel decalcification during fixed orthodontic treatment.
Key words:fluoride-releasing resin sealant;orthodontics;enamel decalcification
固定正畸治疗已经成为临床矫治错牙合畸形的最主要手段。由于粘结托槽过程中对牙釉质的酸蚀以及患者自身口腔卫生问题，导致了釉质脱矿成为了正畸治疗过程中临床最常见的并发症之一[1]。应用氟化物为目前预防釉质脱矿以及龋病发生的有效手段之一，因此，本实验拟采用含氟树脂粘树脂封闭剂封闭牙面后粘结托槽进行错牙合畸形的矫治，通过临床观察，分析其粘结能力以及预防釉质脱矿能力 ......
