摘要
目的探讨天津市不同水氟地区氟斑牙和龋齿影响因素,为进一步干预氟斑牙和龋齿提供科学依据。方法 2018年,在天津市历史低、中和高水氟地区分别选取1所学校,分层整群随机抽样的方法在3~5年级随机抽取2个班级,对儿童进行氟斑牙和龋齿检查,采集儿童尿样和所在村水样,检测尿氟和水氟浓度,并进行问卷调查。结果高氟地区水氟浓度、尿氟浓度、氟斑牙检出率均高于中氟地区(P均<0.05)和低氟地区(P均<0.05),中氟地区水氟浓度、尿氟浓度、氟斑牙检出率均高于低氟地区(P均<0.05),龋齿检出率低于低氟地区(P<0.05)。多因素logistic回归发现,相对于尿氟浓度<0.84 mg/L组,尿氟浓度≥2.39 mg/L组更易发生氟斑牙(OR=17.986,95%CI:8.259~39.169)。母亲高文化程度(OR=0.217,95%CI:0.118~0.400)、家庭年收入10~15万元(OR=0.044,95%CI:0.022~0.088)及15万元以上(OR=0.079,95%CI=0.025~0.248)更不易发生氟斑牙。经常吃甜食是龋齿的危险因素(OR=4.110,95%CI=2.556~6.608),睡前刷牙(OR=0.068,95%CI=0.041~0.112)、尿氟浓度[(1.28,2.39)mg/L(OR=0.456,95%CI:0.239~0.869)]和≥2.39 mg/L(OR=0.347,95%CI:0.173~0.693)是龋齿的保护因素,家庭年收入10~15万元儿童更易发生龋齿(OR=2.729,95%CI:1.502~4.957)。结论本次调查的天津市部分水源高氟地区氟斑牙和龋齿检出率仍然较高,高尿氟是氟斑牙发生的危险因素,也是龋齿的保护因素,应加强健康教育,促进儿童口腔卫生。
Objective To explore the influencing factors of dental fluorosis and caries among children in different areas with various levels of fluoride water of Tianjin and to provide scientific basis for further intervention for dental fluorosis and caries.Methods In 2018,one school was selected from the low-,middle-and high-water fluoride areas in Tianjin,in each of which two classes were randomly selected from grade 3-5 by stratified cluster random sampling.The children were examined for dental fluorosis and caries,urine samples and water samples in local village were collected for the determination of fluoride,and questionnaire survey was conducted also.Results Higher concentrations of fluoride in water and urine,higher detection rate of dental fluorosis were found in high-fluorine area compared with those in middle-fluorine area(all P<0.05)and low-fluorine area(all P<0.05),as well as in middle-fluorine area compared with those in low-fluorine area(all P<0.05);Lower detection rate of caries was found in middle-fluorine area compared with those in low-fluoride area(P<0.05).Multivariate logistic regression showed that higher risk for prevalence of dental fluorosis was found in children with higher urine fluoride(≥2.39 mg/L)compared with those with lower urine fluoride(<0.84 mg/L)(OR=17.986,95%CI:8.259-39.169).Higher education level of mother(OR=0.217,95%CI:0.118-0.400),family annual income of 100-150 thousand Yuan(OR=0.044,95%CI:0.022-0.088)and above 150 thousand Yuan(OR=0.079,95%CI:0.025-0.248)were associated with lower risk for prevalence of dental fluorosis.The risk factor of caries was eating sweets frequently(OR=4.110,95%CI:2.556-6.608).Brushing teeth before going to bed(OR=0.068,95%CI:0.041-0.112),urinary fluoride of[(1.28,2.39)mg/L(OR=0.456,95%CI=0.239-0.869)and≥2.39 mg/L(OR=0.347,95%CI:0.173-0.693)]were the protective factors of caries.The children with family income of 100-150 thousand Yuan were more likely to have caries(OR=2.729,95%CI:1.502-4.957).Conclusion The detection rates of dental fluorosis and caries are higher among children in some high-water fluoride areas in Tianjin.High urine fluoride is the risk factor of dental fluorosis,but the protective factor of dental caries.Health education should be strengthened to promote children’s oral health.
