Objective To explore the prevalence of dental caries in adolescents in Ningbo. Methods Totally 472, 528 and 502 adolescents in the city were surveyed in 2011, 2013 and 2015, respectively, referring to the oral epidemiological survey method recommended by the WHO. Results The caries prevalence in 2015 was significantly higher than that in 2011 (χ2 = 13.52, P <0.01) and 2013 (χ2 = 5.80, P <0.05). There was no significant difference in dentition rate and dental fill rate in three years between rural adolescents The prevalence of dental caries was significantly higher than that of urban adolescents (χ2 = 12.94, P <0.05). There was no significant difference in dental malnutrition rate and dental fill rate among urban and rural adolescents. The prevalence of dental caries among girls was significantly higher than that of boys (χ2 = 5.18, , But there was no significant difference between dentition rate and dental fill rate. The prevalence of dental caries in children aged 7 years was significantly higher than that of children aged 12 years. The caries prevalence of children aged 15 years and 7 years was significantly higher than that of children aged 12 years (χ2 = 47.77, P <0.01) 15 years old (χ2 = 177.44, P <0.05). The prevalence of caries at 12 years old was significantly higher than that of 15 years old (χ2 = 38.03, P <0.01). There was no significant difference in dental malnutrition rate and dental fill rate between the three age groups 3.89 and 0.51, P> 0.05). Conclusion The prevalence of dental caries in adolescents in Ningbo in recent years is high and rising. It should be given the attention of relevant departments and effective prevention and treatment measures should be taken to prevent adolescent caries early detection and early detection and early treatment.
