摘要
目的分析全国2005年中小学生龋齿流行现状和人群龋患程度,为制定儿童青少年防龋措施提供依据。方法选取全国30个省、自治区和直辖市的7,9,12,14和17岁汉族中小学生96829名为调查对象,使用dmf率、DMF率和乳、恒牙龋均为指标。结果乳龋患很严重,7,9岁小学生群体dmf率多高于50%。DMF率随年龄增长而上升,中学生群体大多超过20%。龋失补构成比中,龋补率很低而龋失率较高。乡村小学生dmf率、DMF率和乳龋均超过城市,成为我国学生龋防工作的薄弱环节,学校口腔保健水平仍相当低下。结论针对目前主要问题,应加强乡村学校口腔保健投入力度,建立健全学校口腔保健网等。
Objective To analyze the prevalence of dental Caries and caries degree among school-age children and adolescents in 2005 in China, and to provide bases for the prevention on dental caries. Methods The total subjects were 96 829 Han primary and secondary school students aged 7, 9, 12, 14 and 17 years selected from 30 provinces or cities. They were divided into four groups： Urban and rural, male and female. The dmf incidence, DMF incidence, and mean caries beth of the deciduous and permanent tooth were used as measures. Results Great achievements have been got on the prevention and cure of school dental caries in recent years,but some problems still existed. In most of the 7 - and 9 - year groups, the prevalence of dmf exceeded 50%, and the prevalence of DMF increased with ages, and exceeded 20% in secondary school students. In the constitutional ratio of decaying, missing and filling, the percentage of filling was rather low whereas the percentage of missing was quite high. The prevalence of the dmf, DMF and the mean deciduous caries among the rural primary students were higher than that of their urban counterparts, suggests that the rural student groups became the main loophole of the school dental health practice in China. Condusion According to the present problems, financial support on school oral health should be increased, and should set up a national school oral service network.
