To investigate the oral health status of 18-year-old Iranians in relation to their gender, place of residence and level of education.
Thirty-three calibrated examiners in 2002 collected data as part of a national survey, according to World Health Organization criteria for sampling and clinical diagnoses, across 28 provinces. The study sample was 4,448; male: 2,021 and female: 2,427 made up of urban: 2,564 and rural: 1,884. Oral health status was assessed in terms of number of teeth, decayed teeth (DT), filled teeth (FT), decayed, missing or filled teeth (DMFT), community periodontal index and plaque index.
The mean number of teeth was 27.4, with DMFT: 4.3, DT: 3.0 and FT: 0.7. The mean number of sound teeth was higher (p < 0.01) in men (24.1 vs. 23.3 in women), FT in urban residents (1.0 vs. 0.2 in rural residents) and DT in women (3.3 vs. 2.8 in men). Three of 4 subjects were in need of restorative treatments. All subjects had dental plaque; 387 (8%) healthy gingiva; 1,016 (23%) exhibited bleeding; 2,025 (48%) calculus and 1,020 (21%) deepened pockets. Men's periodontal status was worse than women's (p < 0.002). Low level of education was associated with having 27 or fewer teeth (OR = 1.7), calculus (OR = 1.5) or deep periodontal pockets (OR = 2.7).
A majority of 18-year-old Iranians seem to enjoy a full dentition. High prevalence of dental plaque, calculus, periodontal pockets and untreated dental cariesespecially among underprivileged groups may put them at risk for tooth loss in adulthood.
调查18岁伊朗人的口腔健康状况与性别、居住地点及教育水平之间的关系。
2002年，33名经过校准的检查人员根据世界卫生组织的抽样和临床诊断标准，在全国28个省份收集数据，作为一项全国性调查的一部分。研究样本为4448人，其中男性2021人，女性2427人，包括城市居民2564人，农村居民1884人。根据牙齿数量、龋牙（DT）、补牙（FT）、龋失补牙（DMFT）、社区牙周指数和菌斑指数评估口腔健康状况。
平均牙齿数量为27.4颗，DMFT为4.3颗，DT为3.0颗，FT为0.7颗。男性完好牙齿的平均数量更高（p<0.01）（男性为24.1颗，女性为23.3颗），城市居民的FT更高（城市居民为1.0颗，农村居民为0.2颗），女性的DT更高（女性为3.3颗，男性为2.8颗）。4名受试者中有3名需要进行修复治疗。所有受试者都有牙菌斑；387人（8%）牙龈健康；1016人（23%）牙龈出血；2025人（48%）有牙结石；1020人（21%）牙周袋加深。男性的牙周状况比女性差（p<0.002）。低教育水平与牙齿数量为27颗或更少（OR=1.7）、牙结石（OR=1.5）或深牙周袋（OR=2.7）有关。
大多数18岁的伊朗人似乎拥有完整的牙列。牙菌斑、牙结石、牙周袋和未经治疗的龋齿的高患病率，尤其是在弱势群体中，可能使他们在成年后患牙齿脱落的风险增加。
