摘要
目的:了解辽宁省12岁儿童恒牙患龋状况,为龋病预防提供科学依据。方法:按照第三次全国口腔健康流行病学调查的要求,对辽宁省城乡6个地区36个调查点的792名12岁儿童进行了口腔检查。结果:在792名受检者中,患龋率和龋均分别为30.05%和0.51,农村和城市地区的患龋率分别为28.54%和31.57%,经统计学检验城乡无统计学意义(χ2=0.87,P>0.05),男女患龋率之间有统计学意义(χ2=10.6,P<0.01),显著性龋均指数为1.53。结论:辽宁省12岁儿童龋患明显低于十年前的状况,但患龋率仍达到30.05%,龋齿充填率也较低,龋齿主要集中于第一恒磨牙,仍应加大预防的力度,以降低龋病的发生。
Objective： To study the caries prevalence of permanent teeth among 12 -year -old children in Liaoning province, and provide scientific foundation for the prevention of dental caries. Methods： According to the third national oral health investigation of epidemiology, oral status of 792 children aged 12 in 6 regions of Liaoning province was examined. Results： The prevalence of dental caries and mean DMFT of 792 subjects were 30.05% and 0.51 respectively. The prevalence of caries and mean DMFT of city area was higher than that of rural area, but there was no significant difference by statistical analysis （ X2 = 0.87, P 〉 0.05 ）. The prevalence of female was higher than that of male （ 35.35 % and 24.75 % , X2 = 10.6 ,P 〈0.01 ）. The significant caries index of children among 12 - year - old in Liaoning province was 1.53. Conclusion： The dental caries of children among 12 -year- old in Liaoning province was lower than that of 10 years ago, but the prevalence is still very high （30.05%）. The filling rate of dental caries was low. The dental caries concentrated in the first molar. It should take step to prevent the incidence of dental caries.
