摘要:
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(X2=24.635,P<0.01),恒牙DMF率城乡差异无统计学意义(X2=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X2=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X2=25.079,女生趋势性X2=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.
