摘　　要：目的了解绵阳市12~15岁学生恒牙患龋状况,为制定恒牙龋齿预防措施提供科学依据。方法采用分层、整群、随机等容量抽样的方法,于2019年在绵阳市抽取3个区(县)的11所学校,再以年龄分层,以教学班级为单位抽样构成调查样本,每个年级至少抽取80名学生。结果绵阳市12~15岁学生恒牙患龋率为42.62%,龋均1.14,患者龋均2.67,充填率7.23%。男女生患龋率分别为38.32%和47.28%,差异有统计学意义(χ^(2)=24.75,P<0.05),男女生龋齿充填率分别为4.98%和8.99%,差异有统计学意义(χ^(2)=20.31,P<0.05);12~15岁学生恒牙患龋率分别为36.80%、43.13%、43.63%、48.43%,差异有统计学意义(χ^(2)=20.85,P<0.05);采用χ^(2)检验对影响因素进行分析,女性、饮用含糖饮料和食用甜食频率高以及刷牙次数少的学生患龋率高,差异有统计学意义(χ^(2)=24.75、18.12、7.17、15.06,P<0.05);住校生和非住校生患龋率差异无统计学意义(χ^(2)=0.03,P>0.05)。结论绵阳市12~15岁学生恒牙患龋情况不容乐观,患龋率较高,而充填率较低,应加强口腔健康教育,有针对性地开展综合干预措施,定期进行口腔健康检查,以更好地预防和减少龋齿。Objective To understand the conditions of dental caries out of permanent teeth of students aged 12 to 15 from Mianyang,and to provide scientific basis for making preventive measures of dental caries out of permanent teeth in adolescents.Methods The stratification,clustering and random equal-volume sampling methods were adopted,11 schools from 3 districts(counties)were randomly selected in Mianyang,and then stratified by age in 2019,the investigation samples were formed by sampling with the teaching class as the unit,and 80 students were samples from each unit at least.Results The 12-15 years old students in Mianyang were found to have the morbidity rate of dental caries out of permanent teeth in 42.62%,average rate of dental caries in 1.14,average dental caries of patients in 2.67 and filling rate in 7.23%.The prevalence rate of dental caries in boys and girls was 38.32%and 47.28%,respectively,and the difference was statistically significant(χ^(2)=24.75,P<0.05).The filling rate of dental caries of male and female students was 4.98%and 8.99%respectively,and the difference was statistically significant(χ^(2)=20.31,P<0.05).The prevalence rate of dental caries was 36.80%,43.13%,43.63%and 48.43%in 12-15 years old students,respectively,and the difference was statistically significant(χ^(2)=20.85,P<0.05).Chi-square test was used to analyze the factors,the prevalence rate of dental caries in female and students drinking sugary drinks,eating sweets and brushing their teeth less frequently was high,and the difference was statistically significant(χ^(2)=24.75,18.12,7.17,15.06,P<0.05).The difference in the prevalence rate of dental caries in resident students and non-resident students wasn’t statistically significant(χ^(2)=0.03,P>0.05).Conclusion The situation of dental caries of permanent teeth of students aged 12-15 in Mianyang is not optimistic.The prevalence rate of dental caries is higher,and the filling rate is lower.Oral health education should be strengthened,while targeted comprehensive intervention measures
