The aims of the present study were to describe the dental health status of 12-year-old schoolchildren in Thiruvananthapuram, Kerala, India, and to identify sociodemographic factors, oral health behaviours, attitudes and knowledge related to dental caries experience.
The study took the form of a cross-sectional survey of 838 children in upper primary schools. A two-stage cluster sampling technique was used. Dental caries was measured using World Health Organization criteria. Sociodemographic factors, oral health behaviours, attitudes and knowledge were assessed by a self-administered questionnaire.
The prevalence of dental caries in the permanent dentition was 27%. The mean number of decayed, missing and filled teeth was 0.5 (SD=0.9). The decayed component (D) constituted 91% of the total number of decayed, missing and filled teeth (DMFT). Multiple logistic regression analysis showed that children had a higher risk of having dental caries if they lived in urban area [OR=1.5, 95% confidence interval (CI)=1.1-2.1], had visited a dentist (OR=1.6, 95% CI=1.2-2.2), did not use a toothbrush (OR=1.9, 95% CI=1.2-2.9), consumed sweets (OR=1.4, 95% CI=1.0-1.9) or performed poorly in school (OR=1.7, 95% CI=1.0-2.3).
The prevalence of caries in this sample of 12-year-old schoolchildren was low compared to that in other developing countries. The present study indicated that urban living conditions were associated with more dental caries. Since urbanization is rapid in India, oral health promotion at the present time would be valuable to prevent increased caries prevalence.
本研究旨在描述印度喀拉拉邦特里凡得琅市12岁学童的口腔健康状况，并确定与龋齿经历相关的社会人口学因素、口腔健康行为、态度和知识。
本研究采用对838名小学高年级学生进行横断面调查的形式。使用两阶段整群抽样技术。采用世界卫生组织标准测量龋齿情况。通过自填式问卷评估社会人口学因素、口腔健康行为、态度和知识。
恒牙列龋齿患病率为27%。龋失补牙平均颗数为0.5（标准差=0.9）。龋损部分（D）占龋失补牙总数（DMFT）的91%。多因素logistic回归分析显示，居住在城市地区的儿童患龋齿风险更高[比值比（OR）=1.5，95%置信区间（CI）=1.1-2.1]，看过牙医的儿童（OR=1.6，95%CI=1.2-2.2），未使用牙刷的儿童（OR=1.9，95%CI=1.2-2.9），食用甜食的儿童（OR=1.4，95%CI=1.0-1.9）或学业成绩差的儿童（OR=1.7，95%CI=1.0-2.3）。
与其他发展中国家相比，该样本中12岁学童的龋齿患病率较低。本研究表明，城市生活条件与更多龋齿相关。鉴于印度城市化进程迅速，目前开展口腔健康促进活动对于预防龋齿患病率上升具有重要意义。
