上海某社区6～9岁儿童第一恒磨牙患龋情况调查

Investigation of the caries status of the first permanent molars in children aged 6～9 years in a community in Shanghai

目的:了解社区6~9岁儿童第一恒磨牙的患龋情况,为社区儿童龋病防治工作提供依据。方法:对上海新场社区的3所公办小学2 372名6~9岁学龄儿童的第一恒磨牙龋病进行流行病学调查,其中男生1 299名,占54.76%,女生1 073名,占45.24%。结果:总患龋率为11.80%,女生患龋率为13.79%,男生患龋率为10.16%,差异有统计学意义(χ^2=7.44,P <0.05),患龋率随着年龄的增长逐年增加(χ^2=73.97,P <0.01),下颌第一磨牙患龋率明显高于上颌(χ^2=164.97.75,P <0.01)。结论:第一恒磨牙龋坏率高,应进一步加强口腔卫生宣教,早期进行窝沟封闭。

Objective: To investigate the caries of the first permanent molar in children aged 6~9 years in the community, and to provide evidence for the prevention and treatment of caries in children in the community. Methods: An epidemiological investigation of the first permanent molar caries was conducted in 2 372 school children aged 6 to 9 years from 3 public elementary schools in Xinchang Community of Shanghai, among them, there were 1 299 boys, accounting for 54.76%, and1 073 girls, accounting for 45.24%. Results: The total caries rate was 11.80%, the girl’s caries rate was 13.79%, the boy’s caries rate was 10.16%, and the difference was statistically significant(χ^2=7.44, P<0.05). The caries prevalence rate increased year by year with the increase of age(χ^2=73.97, P<0.01). The caries prevalence rate of mandibular first molar was significantly higher than that of maxillary first molar(χ^2=164.97.75, P<0.01). Conclusion: The caries prevalence rate of the first permanent molars is high,oral hygiene education should be further strengthened, and pit and fissure sealing should be carried out early.
