Abstract: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 than 5-<6 years old preschool children (all P < 0.05). The number of primary tooth caries in 600 preschool children was 1246, 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 preschool children in Nanjing is high, and the age, the place of residence, the education level of the parents, the number of brushing teeth <2 times a day and the annual family income < 5000 yuan all increase the risk of primary tooth caries, which is worthy of clinical attention.
