Abstract: Objective To provide reference for the prevention of deciduous caries of preschool in China by analyzing the influencing factors of deciduous caries of preschool. Methods Computer retrieval of clinical case-control trial literatures meeting the requirements was conducted on common databases including Embase, Cochrane Library, Pubmed, Web of Science, Chinese Academic Journal Full-Text Database(CNKI), Wanfang Database, Viper and Chinese Biomedical Literature Database(CBM)at home and abroad, and the retrieval time was from build libraries to October 2020. Chinese and English literatures related to the factors affecting primary tooth caries in preschool children were collected, and the quality of the included literatures was strictly evaluated by 2 researchers, and the data of middle and high quality literatures were extracted. Results A total of 5 730 subjects were included in 10 articles, including 3 012 cases with caries and 2 718 cases without caries. The Meta analysis results showed that the risk factors of caries in preschool in China were: brushing times <1(OR=3.06,95%CI=2.08-4.48,P<0.05), frequently eating sweets or candies(OR=1.33,95%CI=1.17-1.51,P<0.05), eating sweets before going to bed(OR=2.94,95%CI=1.64-5.26,P<0.05). Gargle habit(OR=0.36, 95%CI=0.23-0.57, P<0.05)is an important protective factor of caries in preschool children in China.
