口腔正畸固定矫正治疗中牙釉质脱矿的临床分析

摘要

目的：探讨口腔正畸固定矫正治疗中牙釉质脱矿发生情况及预防措施。方法：收治正畸固定矫治患者80例，共1469颗牙，对所有患者给予正畸固定矫治技术，指导患者做好口腔卫生和饮食注意事项。在矫正期结束后拆除固定矫正器，以75%酒精清洗牙面，观察牙釉质脱矿情况。结果：80例患者发生牙釉质脱矿现象35例，牙釉质脱矿发病率43.75%；1469颗中牙齿发生釉质脱矿190颗，发生率12.9%。本组1469颗牙中上颌牙745颗，发生釉质脱矿110颗，发生率14.8%，本组1469颗牙中下颌牙721颗，发生釉质脱矿80颗，发生率11.1%。结论：应该重视正畸固定矫正治疗中牙釉质脱矿的发生，采取措施降低或避免发生。%Objective:To explore the occurrence and prevention measures of enamel demineralization in orthodontics fixed orthodontic treatment.Methods:80 patients with orthodontics fixed orthodontic treatment were selected with a total of 1 469 teeth. All patients were given orthodontics fixed orthodontic treatment technology.We guided patients to do oral hygiene and dietary attention.After the correction period,the fixed orthodontic appliance was removed,and the tooth surface was cleaned by 75%alcohol.The enamel demineralization was observed.Results:35 patients had enamel demineralization in 80 patients,and the morbidity of enamel demineralization was 43.75%.190 teeth had enamel demineralization in 1 469 teeth,and the incidence rate was 12.9%.110 teeth had enamel demineralization in 745 upper teeth of 1 469 teeth in this group,and the incidence rate was 14.8%.80 teeth had enamel demineralization in 721 lower teeth of 1 469 teeth in this group,and the incidence rate was 11.1%. Conclusion:It should pay more attention to the occurrence of enamel demineralization in orthodontics fixed orthodontic treatment, and take measures to reduce or avoid the occurrence.
