To describe oral health status of urban Chinese children aged 12 years, to evaluate the pattern of oral health behaviour, and to assess the relative effect of socio-behavioural risk factors on dental caries experience.
A cross-sectional survey of 12-year-old children was conducted in the Hubei Province of China, including urban and periurban groups. The sampling was in accordance with the WHO procedures as applied in the second national survey of oral health. Data were collected by clinical examinations and use of self-administered questionnaires.
The survey was initiated by the National Committee of Oral Health, China, in order to aid the planning and evaluation of school-based oral health care.
A sample of 698 children aged 12 years (96 per cent of original sample) participated in the survey; the sample was balanced by gender and urbanisation (urban/periurban).
The children were clinically examined according to the WHO basic methods and responded to standardised questionnaires on oral health behaviour, knowledge, and attitudes.
The mean DMFT of the children was 0.77 and DT constituted most of the caries index. About 65 per cent of the children had CPITN maximum score 2 (gingival bleeding and calculus). Only 40 per cent brushed their teeth at least twice a day and 46 per cent had seen a dentist within the past year. Variations by urbanisation were observed and the multiple linear regression of dental caries experience revealed that consumption of surgary foods, location and dental visits were the most important independent variables.
This study has shown that systematic oral health promotion programmes for children in China are urgently needed.
描述中国城市12岁儿童的口腔健康状况，评估口腔健康行为模式，并评估社会行为风险因素对龋齿经历的相对影响。
在中国湖北省对12岁儿童进行了横断面调查，包括城市和城郊组。抽样按照第二次全国口腔健康调查中应用的世卫组织程序进行。通过临床检查和使用自填问卷收集数据。
该调查由中国口腔健康全国委员会发起，以协助学校口腔保健的规划和评估。
698名12岁儿童（占原始样本的96%）参与了调查；样本在性别和城市化程度（城市/城郊）方面保持平衡。
根据世卫组织基本方法对儿童进行临床检查，并对关于口腔健康行为、知识和态度的标准化问卷做出回应。
儿童的平均龋失补牙数（DMFT）为0.77，龋补牙数（DT）构成了大部分龋齿指数。约65%的儿童社区牙周指数（CPITN）最高得分为2（牙龈出血和牙结石）。只有40%的儿童每天至少刷牙两次，46%的儿童在过去一年看过牙医。观察到城市化程度的差异，龋齿经历的多元线性回归显示，食用含糖食物、地点和看牙医次数是最重要的自变量。
本研究表明，中国迫切需要针对儿童的系统性口腔健康促进项目。
