BACKGROUND An accurate and valid caries prevention policy is absent in Zhejiang because of insufficient data. Therefore, the aim of this study was to investigate oral health status and related risk factors in 12- to 14-year-old students in Zhejiang, China. MATERIAL AND METHODS Using multi-stage, stratified, random sampling, we recruited a total of 4860 students aged 12 to 14 years old from 6 regions in Zhejiang in this cross-sectional study. Dental caries was measured using the Decayed, Missing and Filled Teeth (DMFT) index and the Significant Caries Index (SiC). Information concerning family background and relevant behaviors was collected in a structured questionnaire. Logistic regression analysis was used to study risk factors related to dental caries. RESULTS The overall prevalence of dental caries was 44% and the mean DMFT and SiC scores were 1.14 and 3.11, respectively. Female students had a higher level of dental caries than male students (P<0.01). The annual increase in caries prevalence was 3% with increasing age, and the DMFT score was 0.15. The results of logistic regression analysis showed that female sex, older age, snacks consumption once or more per day, fair or poor self-assessment of dental health, toothache experience, and dental visits were the most significant risk factors for dental caries, with odds ratios ranging from 1.24 to 2.25 (P<0.01). CONCLUSIONS The prevalence of dental caries in 12- to 14-year-old students in Zhejiang was low, with a tendency to increase compared with previous oral surveys. Female sex, older age, increased sugar intake, poor oral health self-assessment, and bad dental experience were the most important factors increasing dental caries risks.
由于数据不足，浙江省缺乏准确有效的龋病预防政策。因此，本研究旨在调查中国浙江省 12 至 14 岁学生的口腔健康状况及相关危险因素。
采用多阶段、分层、随机抽样方法，在浙江省 6 个地区共招募了 4860 名 12 至 14 岁的学生进行横断面研究。使用龋失补（DMFT）指数和有意义龋（SiC）指数来衡量龋齿情况。采用结构问卷收集家庭背景和相关行为信息。采用 logistic 回归分析研究与龋齿相关的危险因素。
总体龋齿患病率为 44%，平均 DMFT 和 SiC 得分为 1.14 和 3.11。女生的龋齿患病率高于男生（P<0.01）。随着年龄的增长，龋齿患病率每年增加 3%，DMFT 评分增加 0.15。logistic 回归分析结果显示，女性、年龄较大、每天吃零食 1 次或以上、对口腔健康自评一般或较差、有牙痛经历和看牙医是龋齿的最显著危险因素，比值比范围为 1.24 至 2.25（P<0.01）。
浙江省 12 至 14 岁学生的龋齿患病率较低，但与以往的口腔调查相比，呈上升趋势。女性、年龄较大、糖摄入量增加、口腔健康自评较差和不良的牙科经历是增加龋齿风险的最重要因素。
