In this study the prevalence of malocclusion and the need for orthodontic treatment was studied in 1,020 children (541 boys and 479 girls). At the time of examination they were between the ages of 8 years 5 months and 9 years 5 months. The frequency of dental, space and occlusion anomalies was recorded and compared with those in other studies. The need for orthodontic treatment was judged according to the 5-point scale of the Swedish National Board of Health and Welfare (1996). In 32% of the children there was an urgent need for treatment (Grade 3 and 4) in a further 32% treatment would be desirable (Grade 2). There was a little need for treatment (Grade 1) in 24% and no need (Grade 0) in 12%.
在本研究中，对1020名儿童（541名男孩和479名女孩）的错颌畸形患病率及正畸治疗需求进行了研究。检查时，他们的年龄在8岁5个月至9岁5个月之间。记录了牙齿、间隙和咬合异常的发生率，并与其他研究结果进行比较。根据瑞典国家卫生和福利委员会（1996年）的5级量表判断正畸治疗需求。32%的儿童急需治疗（3级和4级），另有32%的儿童适合治疗（2级）。24%的儿童治疗需求较小（1级），12%的儿童无需治疗（0级）。
