目的：了解重庆市学龄前儿童乳牙龋患病情况，同时比较公办幼儿园和民办幼儿园学龄前儿童的乳牙龋患病情况。方法以重庆市渝中区40所民办幼儿园和16所公办幼儿园的5030名3~6岁儿童为调查对象，按照第3次全国口腔健康流行病学调查诊断标准进行口腔检查，提取龋病情况资料，包括患龋率、龋均、龋齿充填率等。采用SPSS21.0软件进行统计学分析。结果5030名受检儿童中，最容易患龋的牙位为上颌乳中切牙和下颌乳磨牙。患龋率为54.08％（2720/5030），龋均为2.58，龋齿充填率为0.98%（127/12993）。随着年龄增长，儿童患龋率和龋均增加（P<0.05）。6岁年龄儿童的龋齿充填率最高（P<0.05），不同性别的龋齿充填率无统计学差异（P>0.05）。民办幼儿园的患龋率、龋均和龋齿充填率分别为61.04%（1656/2713）、3.12和0.35%（30/8465），公办幼儿园的患龋率、龋均和龋齿充填率分别为45.92%（1064/2317）、1.95和2.14%（97/4528），民办幼儿园与公办幼儿园之间有统计学差异（P<0.05）。结论重庆市学龄前儿童乳牙患龋率较高，龋齿充填率较低，其中民办幼儿园学龄前儿童的口腔健康状况明显差于公办幼儿园。

Objective To investigate the status of deciduous dental caries among preschool children in Chongqing city and to compare the oral health status of preschoolers from public and private kindergarten. Methods According to the criteria recommended by The Third National Oral Health Investigation, the deciduous caries of 5 030 preschool children aged 3 to 6 years old from 40 private kindergartens and 16 public kindergartens in Yuzhong district of Chongqing were examined. The prevalence of dental caries and the mean dmft and filling rate were calculated. The results were analyzed using SPSS 21.0 software package. Results Maxillary deciduous central incisors and mandibular deciduous molar were most prone to decay in 5 030 children. The prevalence of dental caries was 54.08% (2 720/5 030). The mean dmft score was 2.58 and the filling rate was 0.98% (127/12 993). The prevalence of dental caries and mean dmft increased gradually as the children were growing up (P<0.05). The rate of filling teeth of the 6 year old group was higher than other groups (P<0.05). No significant difference between males and females were noted (P>0.05). The prevalence rate of deciduous dental caries among private kindergartens was 61.04% (1 656/2 713), with a mean dmft of 3.12 and filling rate of 0.35% (30/8 465). The prevalence rate of deciduous dental caries among public kindergartens was 45.92% (1 064/2 317), with a mean dmft of 1.95 and filling rate of 2.14% (97/4 528). Statistical analysis revealed significant differences in the prevalence rate, mean dmft, and filling rate between two kinds of kindergarten (P<0.05). Conclusion Deciduous dental caries of preschool children is an important problem in Chong-qing city and the children from private kindergarten had very low filling rate.
