【摘要】 目的:了解吉林省12岁儿童人群恒牙龋病和牙周病患病状况及分布,为口腔疾病防治策略提供依据。方法:根据全国第三次口腔健康流行病学调查的方法,对吉林省城乡788名12岁儿童的龋病和牙周病进行了调查。采用SPSS13.0软件包进行数据的统计分析,以龋均、患龋率和牙石、牙龈出血检出率作为统计指标,两样本均数的比较使用t检验,率的比较使用χ2检验。结果:12岁儿童的恒牙患龋率43.65%,龋均为1.07,龋均和患龋率男女之间均有高度显著性差异(P<0.01),农村地区患龋率高于城市地区,但经检验差异无显著性意义,吉林省12儿童的显著性龋均指数为2.89;牙龈出血检出率为53.46%,牙结石检出率和平均检出区段数为76.40%和1.94。牙龈出血检出率和牙结石检出率城乡之间均有高度显著性差异(P<0.01)。结论:12岁年龄组儿童患龋较高,牙周健康状况不良,应加强口腔卫生服务,以促进该人群口腔健康水平。更多还原

【Abstract】 Objective:To assess the prevalence and distribution of caries and periodontal disease among 12 years old children in Jilin province,and to provide the foundation for prevention and treatment strategies of caries and periodontal disease.Methods:A total of 788 subjects aged 12 were selected according the third national oral health survey.The data were collected by oral examination.Prevalence of caries and mean DMFT and the detection rate of calculus and gingival bleeding were used as the statistic index and SPSS13.0 was chosen for the statistical analysis.Independent-sample t test was used for the means comparison of two groups,and Chi-square test was used for the prevalence comparison.Results:The prevalence rate of dental caries was 43.65% with the mean DMFT being 1.07 for permanent teeth among 12 years old children in Jilin province.There were very significant differences between two genders on prevalence rate,and mean DMFT of caries as well(P<0.01).Prevalence rate of dental caries in rural areas was higher than that of urban areas.But there was no significant difference founded by statistical analysis.The significant caries index(SiC)of children among 12 years old was 2.89.The detection rate of calculus was 76.40% and the mean number of areas was 1.94.The detection rate of gingival bleeding was 53.46%.A great significant difference could be seen between the urban and the rural areas on proportion of gingival bleeding and calculus(P<0.01).Conclusion:The prevalence rate of dental caries was high and the status of periodontal health was weak.It should reinforce the oral health care and develop oral health care service in order to improve the oral health among 12 years old children.更多还原
