The effective management of a public dental health system requires accurate data on the needs of the population. Previous assessments of the levels of orthodontic treatment need in populations, by both epidemiologists and orthodontists, vary considerably. This paper presents the findings of two independent investigations into orthodontic treatment need in the United Kingdom using the Index of Orthodontic Treatment Need (IOTN, Brook and Shaw, 1989). The results indicate that approximately one-third of 11-12-year-olds were in objective need of orthodontic treatment. The basis for allocation to the treatment need groups was similar in both studies, as were the proportions of the most severe occlusal traits.
公共牙科保健系统的有效管理需要有关人群需求的准确数据。以往流行病学家和正畸医生对人群正畸治疗需求水平的评估差异很大。本文介绍了两项使用正畸治疗需求指数（IOTN，布鲁克和肖，1989年）对英国正畸治疗需求进行的独立调查结果。结果表明，约三分之一的11至12岁儿童客观上需要正畸治疗。两项研究中分配到治疗需求组的依据相似，最严重咬合特征的比例也相似。
