摘　　要：目的:研究1.23%氟化泡沫在固定正畸治疗过程中预防釉质脱矿的临床效果。方法:经签字同意进入实验的固定正畸患者40例,随机分为A、B两组,每组20名。A组单纯口腔卫生措施,B组在口腔卫生措施的基础上使用1.23%氟化泡沫。两组患者从治疗起始,每月均使用Canon60D专业相机拍摄一次牙牙合照片,共13次,观察时间为13个月。临床检测指标为牙面是否出现新增的白垩色斑点或龋洞,计算牙釉质脱矿指数(EDI)。结果:1从12次牙釉质脱矿变化看,A、B两组的牙釉质脱矿率均随着时间的延长而增高;2两组EDI指数的平均数:A组高于B组,有统计学意义(t=2.929,P=0.008)。结论:1固定正畸所引起的牙釉质脱矿的发生率和严重程度与正畸时间呈正相关;2在口腔卫生措施的基础上使用1.23%氟化泡沫预防固定正畸过程中的牙釉质脱矿是一种有效的措施。Objective： To study the effect of 1.23% fluoride foam in prevention of enamel demineralization during fixed orthodontic. Methods： 40 fixed orthodontic patients were randomly divided into group A, taken simple oral hygiene measures, and group B, 1.23%fluoride foam was used besides simple oral hygiene measures. From the beginning of treatment, patients of both groups were taken photos of teeth monthly with Canon60D professional photo camera with a total of 13 times, the observation time was 13 months. The clinical index was whether there was new chalk colored spots or cavities on the surface of tooth and enamel demineralization index （EDI） was calculated. Results： ①Judged from the changes of enamel demineralization in 12 observations, enamel demineralization rates in both groups were increased with the orthodontic time. ②the average EDI of A group was higher than that of B group （t = 2.929, P= 0.008）, and statistically significant. Conclusions： ①The incidence and severity of enamel demineralization caused by fixed orthodontic were positively correlated with orthodontic time.②1.23%fluoride foam used on the basis of oral hygiene measure for the prevention of enamel demineralization during fixed orthodontic was an effective measure.
