衢州市2000名3～6岁儿童龋病患病情况分析

Analysis of the prevalence of caries in 2 000 3 ～ 6 year-old children in Quzhou

目的调查分析衢州市2000名3～6岁儿童龋病情况,探讨儿童龋病发病因素,为儿童龋病的预防提供依据。方法采用某医院自行设计的口腔保健家长问卷调查表和乳牙龋齿检查表,对衢州市2 000名3～6岁儿童进行龋病情况调查分析。结果衢州市2 000名儿童的龋病患病率随着年龄的增加逐渐增大,4岁以上组别儿童龋病患病率均大于50%。男童患龋率(60.48%)高于女童(46.02%),城区儿童患龋率(62.98%)高于乡村儿童(43.36%),组间差异有统计学意义(P<0.001)。儿童龋、失、补齿的龋均随年龄增长逐渐增加。开始刷牙年龄大、一天刷牙次数少、每次刷牙时间短、没做过龋齿预防、不使用含氟牙膏、没做过医院口腔检查、晚上刷牙后吃东西、有吃糖和零食的习惯、食后不马上漱口,不帮助孩子刷牙均是儿童龋病发生的危险因素。结论衢州市3～6岁儿童龋病患病率较高(>50%),应针对儿童龋病发生的危险因素采取措施,积极干预降低患病率。

Objective To investigate and analyze the caries of 2 000 3~6 year-old children in Quzhou,and to explore the factors of children's caries to provide the basis for the prevention of caries in children.Methods The dental caries situation of 2 000 3~6 year-old children in Quzhou was investigated by self-designed questionnaire of oral health care and deciduous dental caries checklist.Results The prevalence of dental caries in 2 000 Quzhou children increased gradually with the increase of age,and the prevalence of dental caries was more than 50%in children 4 years old and above.The incidence of dental caries(60.48%)of boys was higher than that of girls(46.02%),and the incidence of urban dental caries(62.98%)was higher than that of rural children(43.36%),with statistical significance(P<0.001).Children′s dental caries,tooth loss and repair of teeth were gradually increasing with age.Starting brushing the teeth at a late age,fewer times of brushing teeth a day,shorter time of brushing teeth,without the prevention of dental caries,no using of fluoride toothpaste,without hospital oral inspection,eating after brushing at night,habits of eating sugar and snacks,without immediately mouthwash after eating,and not helping children brush teeth are the risk factors for the occurrence of child caries.Conclusion The prevalence rate of 3~6 year-old children in Quzhou is high(>50%),and measures should be taken to reduce the morbidity rate actively according to the risk factors of caries in children.
