To determine the current prevalence and severity of caries in primary dentition in a preschool population in 2 provinces in China, and to investigate the relationship between caries experience and sociodemographic factors, parental characteristics, dietary habits, and oral hygiene practice.
A cross-sectional survey was conducted on a representative sample of Chinese preschool children aged 3 to 5 years. Clinical examinations were carried out on 2,014 children using the method and criteria established by the World Health Organization. Structured questionnaires for information related to the sociodemographic background, oral hygiene practices, and dietary habits of the children were completed by their mothers.
Overall, 45% of children were caries free, and 14% had rampant caries. The mean dmft and dmfs values were 2.57 and 4.25, respectively. The caries prevalence and severity increased with age. The children from rural areas brushed their teeth less regularly and had a higher level of caries experience than those from urban areas. Significant predictors of caries experience were location, area, age, mother's education level, and consumption of fruit juice from a feeding bottle.
These data indicate that a high proportion of young Chinese children had dental caries and that most decayed teeth were left untreated. The prevalence and severity of caries was associated with socioeconomic status and dietary factors in this sample of children.
确定中国两个省份学龄前儿童乳牙列龋齿的当前患病率和严重程度，并调查龋齿经历与社会人口统计学因素、父母特征、饮食习惯和口腔卫生习惯之间的关系。
对3至5岁具有代表性的中国学龄前儿童样本进行了横断面调查。使用世界卫生组织制定的方法和标准对2014名儿童进行了临床检查。由儿童的母亲填写有关儿童社会人口统计学背景、口腔卫生习惯和饮食习惯的结构化问卷。
总体而言，45%的儿童无龋齿，14%的儿童患有猖獗性龋齿。平均dmft和dmfs值分别为2.57和4.25。龋齿患病率和严重程度随年龄增长而增加。农村地区的儿童刷牙频率较低，龋齿经历水平高于城市地区的儿童。龋齿经历的重要预测因素是地点、地区、年龄、母亲的教育水平以及用奶瓶喝果汁。
这些数据表明，很大比例的中国幼儿患有龋齿，且大多数龋齿未得到治疗。在这个儿童样本中，龋齿的患病率和严重程度与社会经济地位和饮食因素有关。
