Objective To understand the prevalence of caries in primary and secondary school students in minority counties in Guangxi Zhuang Autonomous Region and to provide reference for future oral hygiene. Methods According to the national investigation plan, we conducted a health checkup on primary and secondary schools and high school students in Dahua Yao Autonomous County and established a student health record. Results 53.98% of primary and secondary schools and all high school students in the county had health checkups, accounting for 66.02% of the total number of students in the county. Among them, 58.59% were primary students, 73.13% were middle school students and 93.71% were high school students. The overall prevalence of caries was 41.45%. The caries prevalence among primary, middle school and high school students was 51.94%, 27.68% and 28.26% respectively. The caries prevalence of urban and rural students overall compared, the difference was statistically significant (χ2 = 72.88, P <0.05). Students per capita number of dental caries 2.7. Conclusion In addition to primary school students in the county, the overall caries prevalence rate is lower than the level of the whole region, primary caries prevention and treatment should be strengthened.
