龋齿是小儿时期最多见的牙病。特别是乳牙的龋病,发病率高,其发展速度也比成人快。目前儿童龋齿的发病呈上升趋势,为了提高儿童的健康水平,对龋齿做到早预防早治疗的目的,我所儿保医师自1990～1993年在我区0～7岁儿童健康查体时,对龋齿与年龄的关系进行了调查,结果:(1)1990～1993年检出患龋16267人,患龋率为36.2％,其中男患龋8290人,患龋率36.7％,女患龋7977人,患龋率35.5％,男女患龋比较P>0.05,说明龋齿与性别无明显差异。(2)龋齿与年龄的关系:0～3岁受检人8658人,患龋600人,患龋率6.90％;3～4岁受检9963人,患龋1883人,患龋率18.9％,4～7岁受检26316人,患龋13784人,患龋率52.38％。以上数据经统计学处理显示,3～4岁与0～3岁两组比较有显著差异(X~2=574.3,P<0.001),4～7岁与3～4岁两组相比较也具有显著差异(X~2=
Dental caries is the most common dental disease in infancy. In particular, deciduous teeth caries, the high incidence of its development faster than adults. At present, the incidence of dental caries in children is on the rise.

(2) The relationship between dental caries and age: 8658 subjects aged 0 ~ 3 years, 600 people with caries, 6.90% caries prevalence; 9963 people aged 3 ~ 4 years, 1883 people suffering from caries, caries rate 18.9% There were 26,316 people aged 4 to 7 years old, 13,784 people suffering from caries and 52.38% caries. The above data by statistical analysis, 3 to 4 years old and 0 to 3 years old two groups were significantly different (X ~ 2 = 574.3, P <0.001), 4 to 7 years old and 3 to 4 years old compared with the two groups also have Significant difference (X ~ 2 =
