目的： 了解四川省12岁儿童组（1998年出生）在2010年和2011年的患龋状况，监测龋病的患病趋势，为四川省口腔卫生保健规划提供信息和科学依据。方法 根据WHO口腔健康调查基本方法，采用多阶段、分层随机抽样，抽取四川省12岁儿童（1998年出生） 733名，对其患龋状况连续调查2年（2010年和2011年）。采用SPSS 17.0软件进行统计学分析。结果 四川省12岁儿童的患龋率、龋均及龋面均分别为34.8％、0.93、1.09，1年后儿童的患龋率、龋均及龋面均显著升高（44.3%、1.08、1.40）（P<0.01）。恒牙萌出数女性高于男性（P<0.05）。儿童2010年和2011年的显著性龋均指数分别为2.54、2.90，龋补充填比分别为4.2%、6.5%，1年间的龋齿发病率为9.6%。结论 四川省12岁儿童恒牙的患龋率较高，随着年龄的增加患龋情况呈现上升趋势，龋病治疗情况差，龋齿发病率较高，应立即采取各种预防治疗措施以降低龋齿发病率。%Objective This study aims to investigate the dental caries status of 12-year-old children (born in 1998) in Sichuan province in 2010 and 2011, monitor the tendency of dental caries, and update available information and scientific basis for oral health care program. Methods The oral health of 733 twelve-year-old children was surveyed for two consecutive years according to the methods proposed by the World Health Organization. The children were selected using multi-stage, stratified, randomized sampling. The collected data were analyzed using SPSS 17.0 software. Results Caries prevalence, DMFT, and DMFS in 12-year-old children were 34.8%, 0.93, and 1.09, respectively, and increased to 44.3%, 1.08, and 1.40 in the following year. The eruption of permanent teeth among females was higher than that of males (P<0.05). The significant caries index was 2.54 in 2010 and 2.90 in 2011. F/D+F were 4.2% and 6.5% separately. Annual incidence of dental caries was 9.6%. Conclusion Caries prevalence in the permanent teeth of 12-year-olds is high and worsens as the children age. Despite the high incidence of dental caries, the filling rate is low, hence the need for immediate preventive measures.
