上海市某幼儿园1995-2005年儿童乳牙患龋状况分析

Prevalence of Dental Caries for Deciduous Teeth in a Kindergarten from 1995 to 2005

目的了解上海市幼儿患龋状况及变化趋势,为幼儿龋病预防和治疗工作提供科学依据。方法分别于1995年、2000年和2005年对复旦大学医学院附属幼儿园2～5岁儿童进行口腔健康检查,统计受检儿童的患龋率、受检者龋均(dft)及龋蚀指数(CSI)。结果受检儿童的患龋率从1995年的61.3%下降至2005年的46.5%(P<0.01),受检者龋均(dft)从1995年的(3.11±3.79)降至2005年的(2.12±3.18)(P<0.01),龋蚀指数(CSI)没有下降。每次检查儿童患龋率、受检者龋均(dft)及龋蚀指数(CSI)均呈现由低年龄组到高年龄组升高的趋势。结论该幼儿园儿童患龋状况有所好转,儿童龋病防治工作取得一定成效。但有一部分儿童患龋情况特别严重,有"两极化"的趋势。

Objective To study the characteristics and trend of dental caries status of children in Shanghai in recent years, and to provide scientific evidence for children g prevention and treatment of dental caries. Methods Oral health examinations were carried out among 2 - 5 years old children in same kindergarten affiliated to Medical School of Fudan University in 1995,2000 and 2005 respectively. The prevalence of caries, average dft（decayed and filled teeth） and CSI （ Caries Severity Index ） were calculated and analyzed statistically. Results The prevalence of caries decreased from 61.3% in 1995 to 46.5 % in 2005 （ P 〈 0.01 ） , the dft decreased from 3.11±3.79 in 1995 to 2.12±3.18 in 2005 （P〈0.01） , no changes of CSI were observed. Tendency of increasing prevalence of caries was observed by ages from 2 to 5 years old in each examination, as well as dft and CSI. Conclusion The dental caries status improved in this kindergarten from 1995 to 2005. However, it still severe in some children. It seems a polarization phenomenon exists in dental caries of children.
