目的对于口腔正畸固定矫治器使用中牙釉质脱矿情况进行研究。方法 70例(共1468颗牙齿),固定矫治患者牙釉质脱矿的临床情况,对牙釉质脱矿的发病率、好发部位、好发牙位进行统计分析。结果 70例固定矫治患者有牙釉质脱矿现象的发病率为57.1%;牙釉质脱矿好发牙位为上颌侧切牙,发生率19.6%;发生部位多位于正畸托糟龈方釉质区域,占48.4%。结论临床工作者应掌握正畸治疗中牙釉质脱矿的影响因素并采取针对性的预防措施,降低正畸治疗中牙釉质脱矿发生率,保障患者的口腔健康。
Objective To study the demineralization of enamel in orthodontic appliance. Methods Seventy cases (total 1468 teeth) were enrolled in this study. The clinical situation of enamel demineralization in patients undergoing fixed orthodontic treatment was analyzed statistically. Results The incidence of enamel demineralization was 57.1% in 70 patients undergoing orthodontic treatment. The most favorable tooth enamel demineralization was the maxillary lateral incisor, with a incidence rate of 19.6%. Most of the sites were located in the gingival enamel area of orthodontic care. Accounting for 48.4%. Conclusion Clinicians should master the influencing factors of enamel demineralization in orthodontic treatment and take targeted preventive measures to reduce the incidence of enamel demineralization in orthodontic treatment and ensure the oral health of patients.
