摘要:
了解河南省7~9岁儿童第一恒磨牙萌出、患龋、窝沟封闭及龋病充填情况,为促进儿童第一恒磨牙的早预防、早治疗及儿童口腔保健提供依据.方法 对2015年中国儿童口腔疾病综合干预项目工作信息管理系统中河南省数据进行统计分析.结果 2015年河南省7~9岁学龄儿童第一恒磨牙萌出率为86.7%,患龋率为26.8%,龋均0.6;患龋儿童已接受充填的有935人,充填率为5.2%.女生第一恒磨牙的患龋率(31.3%)高于男生(23.1%)(x2=569.894,P<0.05),城市(32.3%)高于农村(18.0%)(x2=1 663.925,P<0.05).人均窝沟封闭牙数为3.3颗,男生窝沟封闭率(95.1%)低于女生(95.8%)(x2=55.083,P<0.05),农村(96.3%)高于城市(94.7%)(x2=251.108,P<0.05).结论 河南省7~9岁学龄儿童第一恒磨牙患龋率较高,而充填率相对较低.儿童和家长的口腔保健意识有待进一步提高.
Abstract:
Objective To survey current situation of eruption,caries and fissure sealant on the first permanent molar among children aged 7-9 years old in Henan province,to provide the basis for oral health.Methods Data were from Information System of Oral Disease Comprehensive Intervention Project among Chinese Children in Henan Province collected in 2015.Results The eruption rate was 86.7%,the caries prevalence was 26.8%,and the mean DMFT was 0.6 of the first permanent molar among children aged 7-9 years old in Henan.The dental caries filling rate was 5.2%.The girls' caries prevalence rate (31.3%) was significantly higher than boys'(23.1%) (x2 =569.894,P<0.05).The caries prevalence in urban area (32.3%) was significantly higher than those in rural children(18.0%) (x2 =1 663.925,P<0.05).The number of per capital sealing tooth was 3.3.Sealing rates of the first permanent molar in boys (95.1%) was lower than that of girls'(95.8%) (x2 =55.083,P<0.05),and sealing rates in the rural area (96.3%) was higher than in urban area (94.7%)(x2=251.108,P<0.05).Conclusion Oral health is not optimistic among children in Henan Province,with relatively high dental caries rate and low filling rate.The oral health awareness among children and their parents should be further improved.
