目的比较学龄前儿童正畸治疗后采取不同防龋措施的防龋疗效。方法将进行正畸治疗的学龄前儿童共2100名,随机分为三组,分别为氟化泡沫与窝沟封闭组、口腔健康教育组和对照组。结果氟化泡沫与窝沟封闭组、口腔健康教育组的龋患率明显低于对照组,有统计学意义;氟化泡沫与窝沟封闭组与口腔健康教育组作为观察组的患龋率无统计学差异。结论对正畸治疗的学龄前儿童进行氟化泡沫与窝沟封闭及口腔健康保健教育意义重大,可以有效减少接受正畸治疗儿童的龋患率。
Objective To compare the anti-caries effect of different anti-caries measures after preschool children’s orthodontic treatment. Methods A total of 2,100 preschoolers with orthodontic treatment were randomly divided into three groups: fluoridated foam and fissure sealant group, oral health education group and control group. Results The prevalence of dental caries in the fluoride foam group and the pit and fissure sealant group was significantly lower than that in the control group, and there was no statistic difference between the fluoride foam group and the pit and fissure sealant group and the oral health education group as the observation group Differences Conclusions Fluoride foam, pit and fissure sealant and oral health care education for preschool children with orthodontic treatment are of great significance and can effectively reduce the caries prevalence in children receiving orthodontic treatment.
