The objectives of this cross-sectional study were to determine the prevalence of caries, severe caries and gingivitis in Tehran primary-school children and to analyse the relationship between children's oral hygiene habits and prevalence of these oral health diseases. Data were collected on the oral hygiene habits of 1271 Tehran schoolchildren (637 boys, 634 girls) aged 9-13 years. Clinical examinations were performed to determine the decayed, missed and filled teeth (DMFT) and the presence of gingivitis. Total DMFT > or = 1 was observed in 83.3% of children; 55.5% had tDMFT > or = 4 and 87.7% had > or = 1 site affected by gingivitis. Dental visits of 48.2% of children were limited to toothache occasions and parents' lack of belief in the importance of oral health was the most commonly cited reason (P < or = 0.05). The source of oral health education had the strongest independent association with severe dental caries (OR= 2.35; 95% CI: 1.80-2.60); dental flossing frequency was the strongest predicting factor correlated with gingivitis (OR = 3.51; CI: 1.46-8.44).
本横断面研究的目的是确定德黑兰小学生龋齿、重度龋齿和牙龈炎的流行情况，并分析儿童口腔卫生习惯与这些口腔健康疾病流行之间的关系。研究收集了 1271 名 9-13 岁德黑兰学童（637 名男生，634 名女生）的口腔卫生习惯数据。通过临床检查确定龋齿、失牙和补牙（DMFT）以及牙龈炎的存在情况。83.3%的儿童 DMFT>或=1；55.5%的儿童 tDMFT>或=4，87.7%的儿童有>或=1 个部位受牙龈炎影响。48.2%的儿童看牙医仅限于牙痛时，家长对口腔健康重要性的认识不足是最常见的原因（P<或=0.05）。口腔健康教育的来源与严重龋齿有最强的独立相关性（OR=2.35；95%CI：1.80-2.60）；牙线使用频率是与牙龈炎最相关的最强预测因素（OR=3.51；CI：1.46-8.44）。
