摘要
目的:了解成都市城乡地区学龄前儿童的乳牙龋患病情况,同时比较城乡地区幼儿园学龄前儿童的乳牙龋患病情况,为儿童龋病预防措施提供参考。方法:以成都市主城区17所幼儿园及新津县40所幼儿园共14581名3~6岁儿童为调查对象,依照第三次全国口腔健康流行病学调查诊断标准进行口腔检查,并收集龋病检查情况资料,包括患龋率、龋均等,采用SPSS 24.0软件进行统计学分析。结果:成都主城区5319名受检儿童中,患龋率为49.46%(2631/5319),龋均为1.81;新津县9262名受检儿童中,患龋率为53.22%(4929/9262),龋均为4.82。不同年龄段的患龋率不完全相同(χ2=142.481,P<0.001),其中3岁组患龋率低于其他三个年龄段(P<0.05);主城区与郊县患龋率分别为49.46%和53.22%,郊区学龄前儿童患龋率明显高于主城区儿童(χ2=19.064,P<0.001)。结论:成都市学龄前儿童患龋率较全国水平低,郊县学龄前儿童的患龋率和龋均高于主城区儿童。
Objective:To investigate and compare the prevalence of deciduous dental caries among preschool children from kindergartens in the urban and suburban areas of Chengdu,China,and to provide a reference for preventive measures against caries in children.Methods:A total of 14581 children aged 3~6 years from 17 kindergartens in the urban area of Chengdu and 40 kindergartens in Xinjin County were enrolled in this study.Oral examination was conducted in accordance with the diagnostic criteria of the Third National Oral Health Epidemiological Survey,and data on dental caries were collected and calculated,including caries prevalence rate and decayed,missing,and filled teeth(DMFT).SPSS 24.0 software was used for statistical analysis.Results:Among the 5319 children from the urban area of Chengdu,the caries prevalence rate was 49.46%(2631/5319)with a DMFT of 1.81,while among the 9262 children in Xinjin County,the caries prevalence rate was 53.22%(4929/9262)with a DMFT of4.82.The caries prevalence rate was different between different age groups(c2=142.481,P<0.001),significantly lower in the 3-year-old group than in other age groups(P<0.05).The preschool children in the suburban area had a significantly higher caries prevalence rate than those in the urban area(53.22%vs 49.46%,c2=19.064,P<0.001).Conclusion:The caries prevalence rate among preschool children in Chengdu is lower than the national average level.The preschool children in the suburban area of Chengdu have higher caries prevalence rate and DMFT than those in the urban area.
