Objective To analyze the prevalence of caries in primary and secondary school students in Lanzhou City in 2014 and provide evidence for the development of caries prevention and control measures. Methods The prevalence of caries in 1 411 primary and secondary school students aged 4, 9, 12, and 14 years old in urban and rural areas of Lanzhou City was analyzed based on the data of the investigation of physical and health status of students in Lanzhou in 2014. Results The rate of deciduous caries among male and female students in Lanzhou City in 2014 was 57.83% and 57.40% respectively, both decreased with the increase of age. The caries prevalence of permanent teeth in boys and girls were 39.03% and 51.78% respectively, which increased with age. The caries prevalence rates of deciduous teeth in urban and rural boys were 53.27% and 62.57% respectively, with significant difference (χ2 = 6.476, P <0.05). The deciduous caries prevalence in urban and rural girls were 55.70% and 58.87% respectively, with no significant difference (χ2 = 2.732, P> 0.05). The caries prevalence rates of permanent teeth in urban and rural boys were 35.10% and 42.73% respectively, with significant difference (χ2 = 4.178, P <0.05) 44.20%, 59.55%, the difference was statistically significant (χ2 = 10.897, P <0.05). Conclusion The prevention and treatment of dental caries in primary and secondary school students in Lanzhou is arduous. The focus of anti-caries work in rural areas should be placed in rural areas.
