Objective: To investigate the risk factors of caries in permanent teeth of 12-year-old and 15-year-old students in rural and urban areas and the influencing factors of the number of dental caries that have suffered from caries. Methods: The risk factors for caries in 12 and 15-year-olds in rural and urban areas and the influencing factors on the number of dental fillings in caries were collected. Logistic regression analysis was used. Results: The risk of caries in women and cities was higher than that in men and rural areas. The risk of caries increased with age. The number of dental fillings in urban areas was higher than that in rural areas, and the number of dental fillings increased with age. Conclusion: The risk factors for dental caries are related to urban and rural areas, age and gender.
