摘要
目的研究氟化泡沫对学龄前儿童龋齿的预防效果及对乳牙患龋情况、龋面变化的影响。方法选择2016年1-12月共200例3~4岁学龄前儿童,随机均分为两组,对照组给予常规防龋保健指导,观察组在对照组基础上采用氟化泡沫预防龋齿,每6个月干预1次,共干预治疗4次。观察比较两组的新增龋率、龋均、DMFT指数、浅龋再矿化率。结果两组干预前后龋坏率比较差异均无统计学意义(均P>0.05)。观察组新增龋率显著低于对照组,差异有统计学意义(P<0.05)。干预前,两组龋均比较差异无统计学意义(P>0.05)。干预后,观察组龋均显著低于对照组(P<0.05)。干预前,两组DMFT指数比较差异无统计学意义(P>0.05)。干预后,观察组DMFT指数显著低于对照组(P<0.05)。观察组浅龋再矿化率(36.0%,36例)显著高于对照组(23.0%,23例),差异有统计学意义(χ^2=4.06,P<0.05)。观察组应用氟化泡沫干预过程中,发生误吞4例,发生率为4.0%,无其他不良反应发生。对照组无不良反应发生。结论氟化泡沫对学龄前儿童龋齿的预防效果显著,能够有效控制乳牙患龋情况、龋面变化,从而保护乳牙。
Objective To study the preventive effect of fluoride foam on dental caries in preschool children and its influence on primary teeth caries and caries surface changes.Methods A total of 200 preschool children aged 3-4 years old from January to December in 2016 were selected and randomly divided into two groups.The children in control group were given routine anti-caries health guidance,the children in observation group were given anti-caries health guidance and fluoridated foam to prevent dental caries,then children were treated every six months,and the treatment was performed for 4 times.The rates of new caries,average caries,DMFT,and remineralization rates of superficial caries in the two groups were observed and compared.Results There was no statistically significant difference in the rate of caries between before and after intervention in the two groups(P>0.05).The rate of new caries in observation group was statistically significantly lower than that in control group(P<0.05).Before intervention,there was no statistically significant difference in average caries between the two groups(P>0.05).After intervention,average caries in observation group was statistically significantly lower than that in control group(P<0.05).Before intervention,there was no statistically significant difference in DMFT between the two groups(P>0.05).After intervention,DMFT in observation group was statistically significantly lower than that in control group(P<0.05).The remineralization rate of superficial caries in observation group was 36.0%(36 children),which was statistically significantly higher than that in control group(23.0%,23 children)(χ^2=4.06,P<0.05).In observation group,the ingestion rate of fluoride foam was 4.0%(4 children),no other adverse reaction occurred.In control group,no adverse reaction occurred.Conclusion The preventive effect of fluoride foam on dental caries in preschool children is significant,which can effectively control primary teeth caries and caries surface changes,protect primary teeth.
