A CPITN survey involving Chilean high school students aged 15-19 years was conducted. A random stratified sample by age, sex and socio-economic status was obtained, and comprised 2400 subjects. The total prevalence of periodontal disease (Code 3+4) was 10.49 per cent. There was a significant difference in the prevalence of periodontal disease in males (9 per cent) compared to females (12.16 per cent). The prevalence of periodontal disease was higher in students of low socio-economic status (15.87 per cent) than in students of middle (9.22 per cent) and high socio-economic status (8.93 per cent). The periodontal treatment needs were also higher for students of low socio-economic status than for students of the highest family income. The prevalence of periodontal disease and treatment needs found in Chilean students showed that virtually this entire population needs oral hygiene instruction, that 70 per cent need scaling, and that 10.49 per cent need complex periodontal treatment.
开展了一项针对15至19岁智利高中生的社区牙周治疗需要指数（CPITN）调查。通过年龄、性别和社会经济地位获得了一个随机分层样本，样本包含2400名受试者。牙周病（代码3 + 4）的总患病率为10.49%。男性牙周病患病率（9%）与女性（12.16%）相比存在显著差异。社会经济地位低的学生牙周病患病率（15.87%）高于社会经济地位中等（9.22%）和高（8.93%）的学生。社会经济地位低的学生的牙周治疗需求也高于家庭收入最高的学生。智利学生中发现的牙周病患病率和治疗需求表明，实际上这整个群体都需要口腔卫生指导，70%的人需要洗牙，10.49%的人需要复杂的牙周治疗。
