目的:调查口腔正畸治疗后牙釉质脱矿的发病情况,并探讨对牙釉质脱矿的预防。方法:对90例使用固定矫治器正畸治疗患者治疗前后牙釉质脱矿情况进行观察,并对牙釉质脱矿牙的发病率和好发牙及好发部位进行统计。结果:58例固定矫治患者发生不同程度牙釉质脱矿,发病率为64.4%;牙釉质脱矿好发牙位为上前牙;好发部位是托槽龈方釉质和牙颈部。结论:固定矫治对牙釉质的脱矿损害应引起重视。矫治前应对其可能的危害因素进行充分估计,并采取措施减少固定矫治引起牙釉质脱矿的发生率。
Objective: To investigate the incidence of enamel demineralization after oral orthodontic treatment and to explore the prevention of enamel demineralization. Methods: 90 cases of patients with orthodontic treatment of orthodontic treatment before and after enamel demineralization were observed, and the incidence of enamel demineralized teeth and good hair and the incidence of significant sites statistics. Results: 58 cases of fixed orthodontic patients with varying degrees of enamel demineralization, the incidence rate was 64.4%; tooth enamel demineralization is anterior teeth; good site is the bracket gingival enamel and dental neck. Conclusion: It is necessary to pay more attention to demineralization damage of enamel by fixed orthodontics. Before correction should be fully estimated its possible risk factors and take measures to reduce the incidence of fixed enamel demineralization.
