摘　　要：目的了解并分析重庆万州三峡库区7～9岁移民儿童第一恒磨牙龋病发病状况。方法按照第三次全国口腔健康流行病学调查标准和方法，采取整体抽样的方法，对重庆万州区6所移民小学3927名7—9岁在校学生进行第一恒磨牙龋坏状况检查和问卷调查。结果重庆万州三峡库区7～9岁移民儿童第一恒磨牙患龋率39．2％，龋均0．96，充填率为9．4％。7、8、9岁组第一恒磨牙患龋率分别为20．5％、36．5％、58．7％，龋均分别为0．36、0．88、1．65，不同年龄组间差异具有统计学意义（P〈0．05）。Logistic回归分析结果显示：抚养方式、刷牙频率和含糖食品摄人频率与第一恒磨牙龋病发生密切相关（P〈0．05）。结论重庆万州三峡库区7—9岁移民儿童口腔健康意识和口腔卫生习惯较差，第一恒磨牙患龋率高，充填率低，需加强口腔健康宣传和预防性口腔卫生干预。Objective To investigate the prevalence and related factors of the first permanent molar caries in 7- to 9-year-old children in Three Gorges immigrants of Wanzhou District, Chongqing, China in 2012. Methods An overall sampling method was used, including 3 927 7- to 9-year-old children of Three Gorges immigrants in 6 immigrant primary schools in Wanzhou District of Chongqing, China. The caries of the first per- manent molar was assessed. The collected data were statistically analyzed. A structured questionnaire including oral hygiene habits and oral health knowledge was used. Results The study sample included 3 927 school children. The total prevalence rate of the first permanent molar caries was 39.2% , the caries mean was 0.96, and caries filling rate of the first permanent molar was 9.4%. In 7-, 8-, and 9-year-old groups, the prevalence rates of the first permanent molar caries were 20.5% , 36.5% , and 58.7% , respectively, while the caries means were 0.36, 0.88, and 1.65, respectively. There were statistically significant differences between differ- ent age groups （P 〈 0. 05 ）. Logistic regression analysis showed that parenting, the frequency of teeth brushing, and the frequency of sugar food intake were closely related to the caries prevalence of the first permanent molar in 7- to 9-year-old children of Three Gorges immigrants of Wanzhou District, Chongqing, China. Conclusion The prevalence rate of the first permanent molar caries in 7- to 9-year-old children of Three Gorges immigrants is high, but the caries filling rate is low. Oral health awareness and oral hygiene habits are poor. Oral health education and oral health interventions need to be strengthened.
