目的了解江西省12岁儿童龋患和牙周健康现状,为提高学龄儿童口腔健康水平提供依据。方法采用多阶段、分层、等容量、随机抽样的方法,抽取江西省城乡12岁儿童792名,检查恒牙龋患和牙周情况。结果12岁儿童恒牙患龋率为27.8%,龋均为0.43,患龋率和龋均在城乡之间的差异均有统计学意义,男、女之间差异均无统计学意义;龋齿充填率为6.3%,窝沟封闭率为0.5%,牙龈出血检出率和牙石检出率分别是87.9%和67.3%。结论江西省12岁儿童患龋率虽低,但第一恒磨牙易患龋,龋齿治疗率较低,牙周健康状况较差。应积极开展学校口腔预防保健工作,提高龋病治疗率,改善牙周状况。
Objective To understand the status of dental caries and periodontal health of 12-year-old children in Jiangxi province and to provide basis for improving the oral health of school-age children. Methods A total of 792 children aged 12 years old from urban and rural areas in Jiangxi Province were collected by multi-stage, stratified, equal-capacity and random sampling methods to check the status of permanent teeth caries and periodontal disease. Results The caries prevalence of permanent dentition in 12-year-old children was 27.8%, the caries was 0.43, the caries-bearing rate and caries in both urban and rural areas were statistically significant, there was no significant difference between male and female; Rate was 6.3%, pit and fissure closure rate was 0.5%, the detection rate of gum bleeding and calculus were 87.9% and 67.3% respectively. Conclusions Although the caries prevalence of 12-year-old children in Jiangxi Province is low, the first permanent molars are susceptible to caries. The treatment rate of dental caries is low and the periodontal health is poor. Should actively carry out school oral preventive health care, improve caries treatment rate, improve periodontal condition.
