To study oral health status and treatment need among 15-year-olds in Tehran, Iran in relation to their parents' level of education.
A cross-sectional study based on the WHO criteria, was carried out in 2004 among 15-year-olds (n=506) in Tehran. Data collection was by a self-administered questionnaire and a clinical dental examination to assess dental caries, periodontal conditions and orthodontic treatment needs.
Mean DMFT was 2.1 (95%CI=1.9, 2.4), which comprised DT=0.9, MT=0.2, and FT=1.0. The mean SiC index was 5.2 (95%CI=4.8, 5.5). Mean numbers of sextants with PI scores 0, 1, and 2 were 0.6, 2.1, and 3.3 respectively, and with CPI scores 0, 1, and 2, were 2.1, 3.5 and 0.4 respectively. Need for caries (DT>0) treatment existed in 40% of subjects, for scaling (CPI=2) in 24%, for oral hygiene instructions in 100%, and for orthodontic treatment in 26%. Subjects with caries and dental plaque were fewer among those whose parents had a high level of education (p<0.05). Presence of dental plaque was associated with DT>0 (OR=1.8, p=0.01) and CPI>0 (OR=11.2, p<0.001).
Poor level of oral hygiene among the present 15-year-olds calls for school-based oral health promotion activities focusing on oral self-care.
研究伊朗德黑兰15岁青少年的口腔健康状况及治疗需求与其父母教育水平之间的关系。
2004年，在德黑兰对15岁青少年（n = 506）开展了一项基于世界卫生组织标准的横断面研究。通过自行填写问卷和临床牙科检查收集数据，以评估龋齿、牙周状况和正畸治疗需求。
平均龋失补牙数（DMFT）为2.1（95%置信区间=1.9，2.4），其中龋牙数（DT）为0.9，失牙数（MT）为0.2，补牙数（FT）为1.0。平均简化社区牙周指数（SiC）为5.2（95%置信区间=4.8，5.5）。菌斑指数（PI）评分为0、1和2的牙面区段平均数分别为0.6、2.1和3.3，社区牙周指数（CPI）评分为0、1和2的牙面区段平均数分别为2.1、3.5和0.4。40%的受试者需要进行龋齿（DT>0）治疗，24%的受试者需要进行龈上洁治（CPI = 2），100%的受试者需要接受口腔卫生指导，26%的受试者需要正畸治疗。父母教育水平较高的受试者中，患龋齿和有牙菌斑的人数较少（p<0.05）。牙菌斑的存在与DT>0（比值比=1.8，p = 0.01）和CPI>0（比值比=11.2，p<0.001）相关。
当前15岁青少年的口腔卫生水平较差，需要开展以学校为基础的口腔健康促进活动，重点关注口腔自我护理。
