摘　　要：目的评价学龄前儿童的唾液变形链球菌、唾液流速和缓冲力、口腔卫生状况、饮食和口腔卫生习惯、母亲文化程度和职业等因素在乳牙龋发生中的意义。方法采用病例对照研究方法，对1018名4岁和5岁儿童进行龋齿检查，其中dmft≥6的204人构成高龋组，dmft=0的237人为无龋组。测定两组儿童唾液变形链球菌水平、唾液流速和缓冲力、软垢指数，并由儿童母亲回答统一问卷。结果共有417名儿童纳入结果的统计中。Logistic回归分析结果显示，唾液变形链球菌（OR=3．019）、软垢指数（OR=2．263）、每天吃甜食次数（OR=1．729）、每天喝甜饮料次数（OR=1．496）、奶瓶内容物含糖（OR=2．255）等因素有意义。结论唾液变形链球菌水平高、口腔卫生差、高频率摄入甜食、奶瓶喂养时内容物含糖是乳牙龋的重要危险因素。Objective To evaluate the significance of variables such as saliva mutans streptococci, oral hygiene, dietary habits, oral hygiene habits and socio-economic status in assessing the level of caries risk for preschool children. Methods The case-control study was used. Among 1018 children at the age of 4 and 5, 204 children with dmft≥6 were included in caries group and 237 children in caries free group. Saliva mutans streptococci, saliva flow rate and buffer capacity, and debris index were tested for all children. Their mothers finished the standardized questionnaire for information about dietary and oral hygiene habits of the children, breast and bottle feeding history and socio-econmic status. Results Logistic regression analysis showed that the saliva mutans streptococci（ OR = 3.019）, debris index（ OR = 2. 263 ）, frequency of consumption of snacks and sweets（ OR = 1. 729）, frequency of intake of soft drinks（ OR = 1. 496） and use of sweetened food in nursing bottle（ OR = 2. 255） were significant factors. Conclusions High level of saliva mutans streptococci, bad oral hygiene, frequent intake of sweet food, and sugar contents in nursing bottle were the important risk factors for dental caries on primary teeth.
