Objective To investigate the current situation of dental caries among primary and secondary school students in Shijingshan District of Beijing,and to provide scientific basis for the prevention and treatment of dental caries and oral health promotion among students.Methods By stratified random cluster sampling method,students from 7 primary and secondary schools in Shijingshan District of Beijing were selected for dental caries screening in 2022.SPSS 20.0 was used for statistical analysis.Chi-square test was used for comparison between groups,and the test level wasα=0.05.Chi-square segmentation method was used for pairwise comparison between different grades,and the adjusted test level was α'=0.017.Results A total of 2 513 primary and middle school students were investigated on dental caries in Shijingshan District of Beijing in 2022.The results showed that the prevalence rate of caries was 61.64％,the average caries was 2.19,and the rate of caries replacement was 41.90％among them.The prevalence rate and the replacement rate of caries in female students were higher than those in male students,and the difference was statistically significant(x2=20.502,26.678,all P＜0.05).The prevalence rates of dental caries in different grades showed that,primary school(70.77％)＞high school(55.97％)＞junior high school(52.67％),and the difference was statistically significant(x2=69.245,P＜0.001).The prevalence rate of caries in permanent teeth was 40.63％and the rate of caries replacement was 25.95％.The prevalence rate of permanent tooth caries and the rate of permanent tooth caries replacement in female students were higher than those in male students,and the difference was statistically significant(x2=24.564,30.424,all P＜0.05).The prevalence rate of permanent dental caries among different students was high school(55.85％)＞junior high school(50.53％)＞primary school(23.44％),and the difference was statistically significant(x2=239.068,P＜0.001).Conclusions The prevalence of dental caries among primary and secondary school students in Shijingshan District of Beijing in 2022 was at a high level,among which the prevalence rates of primary school students and girls were higher.Relevant departments should cooperate with schools and parents to do a good job in oral health education for students,carry out comprehensive oral health intervention measures,and actively prevent and control the occurrence and development of dental caries.
