To assess dental caries, periodontal status, malocclusion and absenteeism from school among 12-year-olds in Bhopal district, Central India.
Two-stage random sample of 1238 school children. Decayed missing filled teeth (DMFT), Significant caries index (SiC), community periodontal index (CPI) and dental aesthetic index (DAI) were used to record dental caries, periodontal status and malocclusion. Information on absence from school in the previous year due to pain/discomfort in the teeth or mouth was collected via interviews. Generalized structural equation modelling (GSEM) examined the direct and indirect predictors of absence from school.
A total of 39.1%, 17.3% and 23.9% of children had dental caries, calculus and gingival bleeding respectively. Mean DMFT and SiC scores were 1.82± 1.36 and 3.15 ± 1.47. 5,127 school hours were missed due to oral health problems per 1,000 children. None of the studied variables predicted absence from school. Utilization of dental care was associated directly with gender and malocclusion (p⟨ 0.001). Periodontal status was associated with male gender, nuclear families, tobacco consumption, and malocclusion (p⟨ 0.001). Higher DMFT was associated with male gender, malocclusion and experience of pain/discomfort (p⟨ 0.001).
Poor oral health and a high prevalence of untreated dental caries were noted. Despite a considerable number of missed school hours reported due to dental conditions, none of the studied variables predicted absence from school.
评估印度中央邦博帕尔地区 12 岁儿童的龋齿、牙周状况、错颌畸形和缺课情况。
采用两阶段随机抽样方法，抽取了 1238 名在校儿童。使用龋失补牙数（DMFT）、显著龋病指数（SiC）、社区牙周指数（CPI）和口腔美学指数（DAI）记录龋齿、牙周状况和错颌畸形。通过访谈收集了上一年因牙齿或口腔疼痛/不适而缺课的信息。广义结构方程模型（GSEM）用于检验缺课的直接和间接预测因素。
共有 39.1%、17.3%和 23.9%的儿童分别患有龋齿、牙石和牙龈出血。DMFT 和 SiC 的平均得分分别为 1.82±1.36 和 3.15±1.47。每千名儿童因口腔健康问题而缺课的平均时间为 5127 小时。在所研究的变量中，没有一个可以预测缺课情况。口腔保健的利用与性别和错颌畸形直接相关（p⟨0.001）。牙周状况与性别、核心家庭、吸烟和错颌畸形有关（p⟨0.001）。较高的 DMFT 与性别、错颌畸形和疼痛/不适经历有关（p⟨0.001）。
本研究发现儿童口腔健康状况较差，未治疗的龋齿患病率较高。尽管报告了相当数量的因牙齿状况而缺课的情况，但在所研究的变量中，没有一个可以预测缺课情况。
