目的了解邢台地区幼儿园儿童龋齿患病情况,比较邢台地区城乡幼儿园龋齿患病差异,为开展儿童龋齿预防提供依据。方法对邢台地区农村和城市各12所幼儿园共4 286名儿童进行了口腔检查,用SPSS 17.0进行统计分析。结果 4 286名儿童龋齿患病率为52.94%,其中农村儿童龋齿患病率为55.98%,明显高于城市儿童龋齿患病率的49.95%(χ2=15.643,P<0.01);随着班级的由低变高,患龋率逐渐增高(χ2=164.465,P<0.01)。小班儿童城乡患龋率比较,差异无统计学意义(P>0.05),农村中班和大班儿童患龋率高于城市(P<0.05);患龋齿儿童的龋齿填充率为1.77%,农村龋齿填充率仅为0.91%,明显低于城市龋齿填充率的2.61%(χ2=34.322,P<0.01)。结论邢台地区农村幼儿园儿童龋齿患病率较高,龋齿填充率较低,应加强农村儿童牙齿防护及龋齿填充工作。
Objective To understand the prevalence of dental caries in kindergarten children in Xingtai region and to compare the prevalence of dental caries in urban and rural kindergartens in Xingtai and to provide basis for the prevention of dental caries in children. Methods A total of 4 286 children in 12 kindergartens in rural areas and urban areas of Xingtai City were examined by oral cavity and analyzed by SPSS 17.0. Results The prevalence of dental caries in 4 286 children was 52.94%. The prevalence of dental caries was 55.98% in rural children, which was significantly higher than 49.95% (χ2 = 15.643, P <0.01) of dental caries in urban children. From low to high, caries prevalence increased (χ2 = 164.465, P <0.01). The prevalence of caries prevalence in urban and rural small classes was not statistically significant (P> 0.05). The prevalence of caries was higher in middle-class and middle-class rural children than in urban (P <0.05). The caries filling rate was 1.77% in rural children with caries, The filling rate was only 0.91%, which was significantly lower than 2.61% of urban dental caries filling rate (χ2 = 34.322, P <0.01). Conclusion The prevalence of dental caries in rural nursery children in Xingtai region is high, and the filling rate of dental caries is low. Dental protection and dental caries filling should be strengthened in rural children.
