The prevalence and influencing factors of ECC on Longgui Street in Baiyun District, Guangzhou City: a cross-sectional study

To investigate the prevalence and influencing factors of Early Childhood Caries (ECC) in Longgui Street in Baiyun District of Guangzhou and establish a prediction model to establish a basis for the overall diagnosis and prevention of ECC. Seven kindergartens were randomly selected from seven administrative villages on Longgui Street, and more than 300 kindergartens were needed. A total of 1,096 preschool children were included. The questionnaires were distributed to parents to investigate the oral health behavior and medical treatment behavior of the tested children and the oral health knowledge behavior of the tested parents, and the results were analyzed differently to establish a prediction model. The incidence of dental caries in 1096 preschool children was 18.6%, with age being a risk factor for dental caries (p<0.05, OR>1); only child status being a protective factor for dental caries (p<0.05, OR<1); family income level being a protective factor for dental caries (p<0.05, OR<1); chewing food-feeding children being a risk factor for dental caries (p<0.05, OR>1); starting brushing time being a protective factor for dental caries (p<0.05, OR<1); and toothache informing family members that it is a risk factor for dental caries (p<0.05, OR>1), but this factor is not suitable as a predictive factor because, in many cases, children who inform their parents that they already have dental caries disease. Parents' awareness of whether bacteria can cause gum inflammation and dental caries plays an important role in their oral health knowledge and attitudes. Conclusion: The prevalence of dental caries among preschool children in Longgui Street of Baiyun District is lower than the national level, indicating that remarkable achievements have been made in the prevention of dental caries among preschool children in Longgui Street. Dental caries in preschool children on Longgui Street are closely related to children's age, whether they are only children, parents' education level, parents' oral knowledge, beliefs and behaviors, and children's bad oral behaviors. Oral health behaviors should be cultivated as early as possible, and some aspects of traditional feeding habits should be abandoned.
