Abstract: 【Objective】 To investigate the relationship between gingivitis and permanent teeth caries of children to provide theoretical basis for gingivitis prevention of children. 【Methods】 Multistage stratified cluster random sampling method was used to obtain 1115 samples among 12~13 year-old children in Guangzhou. The methods and criteria of gingivitis and caries were abided by World Health Organization in 1997. The examination indices of gingivitis and caries were scored with GI and DMFT, respectively. Logistic regression analysis was used to explore the relation between gingivitis and permanent teeth caries in 12~13 year-old children in Guangzhou. 【Results】 In the cohort aged 12~13, the prevalence of gingivitis was 72.65%. The prevalence of moderate and severe gingivitis was 28.16% and 5.83%, respectively. The prevalence of caries of the subjects was 25.83%, the non-filled tooth accounted for 73.73% among DMFT. The result of Logistic regression analysis showed non-filled caries was a risk factor of gingivitis in 12~13 year-old children in Guangzhou. 【Conclusion】 The children who had non-filled caries are focus on prevention of gingivitis in Guangzhou.

摘要： 【目的】 探讨儿童牙龈炎与恒牙龋的相关关系,为儿童牙龈炎防治工作提供理论依据。 【方法】 采用多阶段分层整群随机抽样的方法共调查广州市12~13岁儿童1 115人。检查方法和标准参考1997年WHO推荐的《口腔健康调查基本方法》,牙龈炎检查六颗指数牙,龋病检查全口恒牙,分别采用牙龈指数(GI)和DMFT记录检查结果。Logistic回归分析儿童牙龈炎与恒牙龋病的关系。 【结果】 广州市12~13岁儿童牙龈炎患病率72.65%,中、重度牙龈炎患病率分别为28.16%和5.83%。恒牙龋患病率为25.83%,其中未充填龋占龋齿的73.73%。Logistic回归分析显示未充填龋是广州市12~13岁儿童牙龈炎患病的危险因素。 【结论】 广州市12~13岁儿童牙龈炎患病率较高,有未充填龋存在的儿童是广州市儿童牙龈炎重点防治人群。
