One-thousand-and-eighteen 12-year-old children were chosen by use of preselected screening criteria, and disproportionate sampling to participate in a longitudinal study into the dental and social effects of malocclusion. The data has now been used to investigate the effects of malocclusion and orthodontic treatment on craniomandibular disorders. The sampling method was designed to create sub-groups large enough to study effectively the whole range of malocclusion, even those which have a low prevalence. This report will give baseline data in a longitudinal study. Intra-observer variability on recordings of signs of craniomandibular disorders was tested and reproducibility was found to be on an acceptable level. Almost half the children had signs of CMD, but few of these were severe and overall, only a very small minority of children in this sample required treatment. A preliminary examination has been made into possible relationships between the signs and symptoms of CMD, and significant associations were found between headache and several clinical signs.
通过预先选定的筛查标准选取了1018名12岁儿童，并采用不成比例抽样法让他们参与一项关于错牙合畸形对牙齿及社会影响的纵向研究。目前，这些数据已用于调查错牙合畸形及正畸治疗对颅下颌疾病的影响。抽样方法旨在创建足够大的亚组，以便有效地研究错牙合畸形的整个范围，即使是那些患病率较低的类型。本报告将给出一项纵向研究的基线数据。对颅下颌疾病体征记录的观察者内变异性进行了测试，发现重复性处于可接受水平。几乎一半的儿童有颅下颌疾病的体征，但其中很少有严重的，总体而言，该样本中只有极少数儿童需要治疗。已对颅下颌疾病的体征和症状之间可能存在的关系进行了初步检查，发现头痛与几种临床体征之间存在显著关联。
