龋活跃性检测联合氟化物预防学龄前儿童口腔龋齿的临床研究

Clinical study of caries activity detection combined with fluoride to prevent preschool children from dental caries

目的 分析龋活跃性检测联合氟化物对学龄前儿童口腔龋齿的预防价值。方法 选取2021年6月至2022年6月间在石家庄市某幼儿园的136名3~5岁的儿童作为实验组,同期本地区另外一所幼儿园的142名3~5岁的儿童作为对照组。实验组给予口腔健康教育和氟化物应用干预,对照组仅给予口腔健康教育干预。对儿童进行口腔健康检查,测定dt、ds、ft、fs、mt、fs、DI-S等指标,并计算dmft和dmfs;使用龋病易感性检测试剂检测两组儿童龋活跃性风险;使用量表调查干预1年后儿童口腔卫生习惯和饮食习惯情况,对比两组干预效果。结果 干预后,与对照组比较,实验组龋活跃性低风险人数增加,中风险和高风险人数减少,实验组患龋率、SECC患病率、软垢检出率及龋、dt、ds、mt、ms、ft、fs、dmft、dmfs发生占比均低于对照组,实验组在使用含氟牙膏、每天刷牙次数大于等于2次、每次刷牙时间大于等于3 min、家长再刷一遍、睡觉前从不进食、每天饭后漱口大于等于2次这六个方面的占比均高于对照组;不使用牙线、从不进行口腔检查这两个方面的占比低于对照组(P<0.05)。结论 采用龋活跃性检测联合氟化物预防学龄前儿童口腔龋齿,能够使得儿童患龋的情况得到改善。另外,对于学龄前儿童良好口腔卫生习惯和饮食习惯的形成具有一定的促进作用。

Objective To analyze the preventive value of caries activity detection combined with fluoride in preschool children.Methods 136 children aged 3 to 5 years in a kindergarten in Shijiazhuang from June 2021 to June 2022 were selected as the experimental group,and 142 children aged 3 to 5 years in another kindergarten in the same period were selected as the control group.The experimental group was given oral health education and fluoride application intervention,while the control group was only given oral health education intervention.The children were examined for oral health,and the indexes of dt,ds,ft,fs,mt,fs,DI-S were measured,and dmft and dmfs were calculated.The caries susceptibility test reagent was used to detect the caries activity risk of children in the two groups.Use the scale to investigate the oral hygiene habits and eating habits of children after one year of intervention,and compare the effects of the two groups.Results After intervention,compared with the control group,the number of people at low risk of caries activity in the experimental group increased,while the number of people at medium risk and high risk decreased.The incidence of caries,the prevalence of SECC,the detection rate of soft scale,and the incidence of caries,dt,ds,mt,ms,ft,fs,dmft,dmfs in the experimental group were lower than those in the control group.The experimental group was using fluoride toothpaste,brushing teeth more than or equal to 2 times a day,brushing time more than or equal to 3 minutes each time,and the parents brushed again The proportions of never eating before sleeping and gargling more than or equal to twice a day after eating were higher than those of the control group;The proportion of no flossing and no oral examination was lower than that of the control group(P<0.05).Conclusion Caries activity detection combined with fluoride to prevent dental caries in preschool children can improve the situation of caries in children.In addition,it has a certain promoting effect on the formation of good oral hygiene habits and eating habits of preschool children.
