摘　　要：目的调查南京市600例学龄前儿童乳牙龋病现状及影响因素。方法采用分层整群抽样方法,于2017年12月选取南京市650例学龄前儿童进行研究,并对所有学龄前儿童进行口腔检查以及问卷调查。分析不同性别、年龄、居住地学龄前儿童乳牙龋病的发生率;分析学龄前儿童乳牙龋病与睡前进食、定期口腔检查、家长文化程度、开始刷牙年龄、每天刷牙次数、家庭年收入、使用含氟牙膏的关系;分析学龄前儿童乳牙龋病的影响因素。结果所发放的650份问卷调查共收回有效问卷600份,城市学龄前儿童乳牙患龋率低于乡镇学龄前儿童,且3~<4岁学龄前儿童乳牙患龋率低于4~<5岁、5~<6岁学龄前儿童,而4~<5岁学龄前儿童乳牙患龋率低于5~<6岁学龄前儿童(均P <0.05)。600例学龄前儿童乳牙龋病颗数为1246颗,且好发于下颌左侧第二乳磨牙。家长文化程度、每天刷牙次数、家庭年收入均是学龄前儿童乳牙龋病率的影响因素(均P <0.05)。经多因素Logistic回归分析发现,年龄、居住地为乡镇、家长文化程度为高中以下、每天刷牙次数<2次、家庭年收入<5000元均是学龄前儿童乳牙龋病的独立危险因素(均P <0.05)。结论南京市600例学龄前儿童乳牙龋病率较高,且年龄、居住地为乡镇、家长文化程度为高中以下、每天刷牙次数<2次、家庭年收入<5000元均会增加乳牙龋病发生风险,值得临床重点关注。Objective To investigate the status and influencing factors of the primary tooth caries in 600 preschool children in Nanjing City. Methods A total of 650 preschool children in Nanjing were selected for study in December 2017 by stratified cluster sampling method. Oral examination and questionnaire survey was conducted on all preschool children. The incidence of primary tooth caries of preschool children with different genders, ages and places of residence was analyzed, and the relationship between primary tooth caries of preschool children and eating before bed, regular oral examination, parents′ educational level, age at which they began to brush their teeth, number of teeth brushing times per day, annual household income and the use of fluoride toothpaste were analyzed, and the influencing factors of primary tooth caries in preschool children were analyzed. Results A total of 650 questionnaires were collected and 600 valid questionnaires were retrieved. Preschool children′s primary tooth caries rate of the city was lower than the preschoolers of villages and towns, and primary tooth caries rate of 3-<4 years old preschool children was lower than 4-<5 years old,5-<6 years old preschool children, and preschool children′s primary tooth caries rate of 4-<5 years old was lower than5-<6 years old preschool children(all P < 0.05). The number of primary tooth caries in 600 preschool children was1246, and most of them occurred in the second deciduous molar on the left side of the mandible. Parents′educational level, frequency of brushing teeth every day and family income were all the influencing factors of the primary tooth caries rate in preschool children(all P < 0.05).Multivariate Logistic regression analysis found that age,place of residence for townships, parental education below high school, daily brushing times <2 times, family annual income < 5000 yuan were independent risk factors for primary tooth caries of preschool children(all P < 0.05).Conclusion The incidences of primary tooth caries in 600 presch
