紫金县5～6岁学龄前儿童乳牙龋病流行病学调查及防治策略
Epidemiological survey and prevention strategies for dental caries in deciduous teeth among 5-6-year-old pre-school children in Zijin County,Heyuan City,Guangdong Province
摘要
Abstract
Objective:To investigate the prevalence of deciduous teeth caries among 5-6-year-old children,and to provide information to support oral health initiatives for children.Methods:A total of 963 children,aged 5 and 6,from Zijin County were selected by stratified random cluster sampling method.The status of deciduous teeth caries was assessed.Statisti-cal analysis was performed using SPSS 27.0 software.Results:The prevalence of deciduous teeth caries among 5-year-olds was 89.3%,while it was 93.1%among 6-year-olds.The mean decayed-missing-filled teeth(dmft)scores were 6.50 for 5-year-olds and 7.38 for 6-year-olds.The caries filling ratio was low,at 1.3%for 5-year-olds and 1.4%for 6-year-olds.Signifi-cant differences were found in the prevalence of deciduous teeth caries and mean dmft between the two age groups(P=0.035,P=0.001),with the prevalence increasing as age advanced.There was no significant difference in the prevalence of deciduous teeth caries or mean dmft regarding the gender in each group.Among 5-year-olds,both the prevalence of deciduous teeth caries and mean dmft were significantly higher in rural areas than that in urban areas(P=0.004,P=0.009).For 6-year-olds,the mean dmft in rural areas was significantly higher than that in urban areas(P=0.024),while there was no sig-nificant difference in caries prevalence between rural and urban areas.In both age groups,the ratio of filled dental caries was higher in urban areas compared to rural areas(P=0.023,P=0.003).The significant caries index(SiC)for the 5-and 6-year-olds were 11.72 and 12.30,respectively.Conclusion:Caries prevalence is alarmingly high among children aged 5 and 6 in Zijin County,with low caries filling ratio.There is an urgent need to strengthen the prevention and treatment of deciduous teeth caries among preschool children.Public awareness needs to be raised,and the management of children's oral health hab-its should be improved.关键词
