目的了解2005,2010,2014年安徽省城乡学生龋齿患病(龋患)情况及其变化,为开展学生龋齿防治提供参考。方法以2005,2010,2014年安徽省7,9,12和14岁汉族中小学生共8 582人为调查对象,以乳龋失补(dmf)率、恒龋失补(DMF)率为指标,分析近10年患龋率和龋失补的变化。结果 2014年总乳龋率为50.8%,乳龋失补的构成比分别是78.2%,16.8%,5.0%,总乳龋率城乡差异有统计学意义(χ~2=24.635,P<0.01),恒牙DMF率城乡差异无统计学意义(χ~2=0.045,P>0.05);2005,2010,2014年汉族学生的dmf率分别是36.5%,48.1%,50.8%,总体呈上升趋势(趋势性χ~2=61.863,P<0.01);2005,2010,2014年乡村不同性别学生dmf率均呈逐年上升的趋势(男生趋势性χ~2=25.079,女生趋势性χ~2=20.673,P值均<0.01)。结论安徽省中小学生龋齿患病率居高不下。学校、家庭及相关部门应重视中小学生的龋齿问题,加大口腔保健的投入力度。
Objective To understand the prevalence and changes of dental caries among urban and rural students in Anhui Province in 2005, 2010 and 2014, and to provide reference for the prevention and treatment of dental caries in students. Methods A total of 8 582 primary and secondary school students aged 7, 9, 12 and 14 years of age in Anhui Province in 2005, 2010 and 2014 were investigated. The rates of dmf and DMF were analyzed. Nearly 10 years suffering from caries and caries loss of change. Results The total caries prevalence was 50.8% in 2014, and the proportions of milk caries loss were 78.2%, 16.8% and 5.0%, respectively. There was significant difference between urban and rural areas (χ ~ 2 = 24.635, P <0.01) (Χ ~ 2 = 0.045, P> 0.05). The dmf rates of Han nationality students in 2005, 2010 and 2014 were 36.5%, 48.1% and 50.8%, respectively, showing an upward trend (Χ ~ 2 = 61.863, P <0.01). In 2005, 2010 and 2014, the dmf rates of different sexes in rural areas showed a trend of increasing year by year (trend of boys χ ~ 2 = 25.079, trend of girls χ ~ 2 = 20.673, P <0.01). Conclusion The prevalence of dental caries among primary and middle school students in Anhui Province remains high. Schools, families and relevant departments should attach importance to primary and secondary school students dental caries, increase oral health care efforts.
