舌侧正畸治疗中牙釉质脱矿的临床观察及预防措施

Observation of enamel demineralization after lingual orthodontic treatment and exploraqtion of the prevention measures

目的:了解舌侧正畸治疗后牙釉质脱矿情况及氟保护漆预防和减少牙釉质脱矿的疗效,探讨预防脱矿的简便易行方法。方法:将20例舌侧正畸患者随机分为两组进行观察。实验组10例,在舌侧正畸托槽周围牙面涂布氟保护漆;对照组10例,患者仅进行日常的口腔卫生护理。结果:舌侧正畸治疗患者牙釉质脱矿发生率为17.35%,上颌侧切牙脱矿率最高,好发部位部位为托槽龈方和牙齿邻面;实验组牙釉质脱矿程度较对照组明显降低,具有统计学意义。结论:舌侧正畸治疗中使用氟保护漆是预防和降低牙釉质脱矿的有效途径。

Objective The Purpose of this clinical experiment is to know enamel demineralization after lingual orthodontic treatment and the clinical efficiency of fluoride varnish to prevent and reduce enamel demineralization to find a simple and effective to reduce enamel demineralization. Methods 20 cases of lingual orthodontic patients were randomly divided into two groups for observation,the tooth surfaces around tooth brackets were coated with fluoride varnish in 10 orthodontic cases as the test group,and the rest 10 cases as the control group,which only received routine oral health care. Results The incidence of enamel demineralization in patients with lingual orthodontic treatment was 17.35%,lateral incisor enamel on the highest incidence,part of the site for the high incidence was gingival side.Enamel demineralization in test group decreased significantly than the control group , with statistical significance. Conclusion Lingual orthodontic treatment will increase the rate of enamel demineralization,fluoride varnish is an effective way to prevent and reduce enamel demineralization in lingual orthodontic treatment.
