摘　　要：目的了解南宁市民办幼儿园3～7岁学龄前儿童乳牙龋患病及治疗情况。方法随机抽取南宁市3所民办幼儿园402名3～7岁儿童为对象,其中男214名,女188名,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后,提取龋病情况资料,包括患龋率、龋均、龋面均、龋坏充填率等进行统计学分析。结果受检儿童中,261例发现明确龋坏,总患龋率为64.93%,龋均3.56,龋面均6.11,龋坏充填率0.84%。其中3～、4～、5～、6～7岁年龄段人数分别为111、133、108、50例,患龋人数(率)分别为53(47.75%)、89(66.92%)、80(74.07%)和39(78.00%);龋均分别为2.23、3.17、4.86和4.7。统计分析表明患龋率随年龄增大而增高,差别具有统计学意义(χ2=22.34,P<0.001)。结论南宁市民办幼儿园3～7岁儿童乳牙患龋状况严峻,患龋率高,龋坏充填率低。Objective To investigate the dental caries status of pre-school children in private kindergartens in Nanning to provide the basic information among this population. Methods Random samples of 402 children aged 3-7 from three private kindergartens in Nanning were included in this study,including 214 boys and 188 girls. Oral examinations were carried out in June 2008 under the criteria according to the Chinese Third National Epidemiological Sampling Survey of oral health. Results Caries were diagnosed among 261 children examined, with a prevalence rate of 64. 93% , with a mean dmfs as 6. 11, mean dmft 3.58, and the filling rate was 0. 84%. The number of 3-, 4-, 5-, and 6-7-year-old children with caries （the caries prevalence rates） were found to be 53 （47.75%）,89 （66. 92% ） ,80（74. 07% ） and 39（78.00% ）, respectively, and dmft were 2. 23, 3. 17, 4. 86 and 4. 7, respectively. The caries prevalence increased significantly with age in primary dentition （ P 〈 0. 001 ）. Conclusion Children in private kindergartens in Nanning showed a high rate of caries. It is urgent to develop the oral health promotion strategies to reduce the caries prevalence rates among those children.
