【摘要】 目的描述北京2005-2019年12岁儿童患龋状况的纵向变化,并分析北京市窝沟封闭公共卫生项目对12岁儿童患龋状况的影响。方法 15年来在北京地区开展的12岁儿童口腔健康流行病学调查有6次,分别在2005、2011、2013、2015、2017和2019年,样本合计20568人。纵向分析儿童患龋状况和第一恒磨牙窝沟封闭率的变化趋势,并与全国同期数据进行对比。结果 2005年北京12岁儿童患龋率26.3%,全国28.9%,差异无统计学意义(P> 0.05);2015年,北京12岁儿童患龋率29.0%,与10年前结果差异无统计学意义,显著低于全国水平(38.5%)(P<0.05)。北京12岁儿童2011、2013、2015、2017和2019年患龋率分别是24.8%、26.9%、29.0%、31.5%和32.2%,呈上升趋势(P<0.05)。北京2005年12岁儿童第一恒磨牙窝沟封闭检出率是10.2%(81/791),均明显低于之后5次的结果(2011年36.7%,2013年32.4%,2015年45.3%,2017年35.5%,2019年37.5%)(P <0.05)。2011年到2019年合计样本,窝沟封闭检出组和未检出组的龋均分别是0.38±0.85和0.68±1.28,差异有统计学意义(P <0.05)。结论 2015年北京12岁儿童患龋状况低于全国水平,与10年前持平;2011年到2019年北京患龋呈上升趋势,口腔预防保健需要进一步加强。更多还原

【Abstract】 Objective To investigate the dental caries trend of 12-year-old children in Beijing. Methods Six oral health epidemiology surveys were conducted in Beijing from 2005 to 2019, a total of 20568 12-year-old children were sampled. The dental caries status and the percentage of first permanent molar with sealant was longitudinal analyzed, and were parallelly compared with national data. Results The dental caries prevalence for 12-year-old children in 2005 was 26.3%, and the result for national level was 28.9%(P > 0.05). The prevalence of Beijing in 2015 was 29.0%, which was not significantly different with that of Beijing in 2005, but significantly lower than the national level in 2015(38.5%)(P< 0.05). The dental caries prevalence in 2011, 2013, 2015, 2017 and 2019 was 24.8 %, 26.9%, 29.0%, 31.5%and 32.2%(P < 0.05). The percentage of sealant for the first molar was 10.2%(81/791)in 2005, which was significantly lower than the later results. The mean DMFT for all of the sample from 2011 to 2019, with and without sealant was 0.38±0.85 and 0.68±1.28(P< 0.05). Conclusions The dental caries level of Beijing 12-year-old children in 2015 was lower than the national level and remained stable during the past ten years.更多还原
