Objective: To investigate the prevalence of dental caries in the first permanent molars of 12-year-old children in Nanjing and its influencing factors. Methods: A total of 660 children aged 12 years from Nanjing were sampled by random sampling method. The oral health examination and oral questionnaire were conducted. The data were processed by SPSS 13.0 statistical software to analyze the relationship between the prevalence of dental caries and the influencing factors of the first permanent molar in 12-year-old children. Results: The prevalence of dental caries was 31.1% in the first permanent molars of 12-year-old children in Nanjing, 29.6% in boys and 32.2% in girls. Logistic regression analysis showed that there was a significant correlation between the two factors (P> 0.05) and the first permanent molar dental caries (OR> 1). Conclusion: Carbonated drinks are the risk factors for dental caries. Sealing with pit and fissure can reduce the risk of caries.
