A 5-yr longitudinal study on occlusal and functional parameters has been made in 75 children aged 8-11. They were selected at random from an original group of 510 studied 5 yr earlier. The following parameters were measured: frequency of frontal open bite lateral and frontal crossbite, the attrition on molars and on front teeth, the contacts on lateral excursion, pain on condyle palpation, TMJ clicking, deviations in the opening and lateral movement, and the maximal interincisal distance. There was an increase in the percentage of deep bite and crossbite. Attrition on molars was seen in 41% and on front teeth in 13% of the children. No real pattern could be observed as a function of age. The mean maximal opening range was 43.7 mm, varying between 23 and 52 mm. Restricted opening was found in one girl. In 60% a deviation in the opening has been found. In 26% TMJ sounds were observed and 28% had pain on condyle palpation. In most of the children the symptoms were very mild to moderate. No significant correlation could be found between dysfunctional signs and occlusal parameters. The present results did not provide any conclusive answer to the tremendous increase in dysfunctional signs over this 5-yr period. The treatment need is, however, low and should not be overestimated.
对75名8至11岁儿童进行了一项为期5年的咬合和功能参数纵向研究。他们是从5年前研究的510名儿童的原始组中随机挑选出来的。测量了以下参数：前牙开合、侧方和前方反合的频率，磨牙和前牙的磨耗，侧方运动时的接触，髁突触诊时的疼痛，颞下颌关节弹响，开口和侧方运动的偏差，以及最大切牙间距离。深覆合和反合的百分比有所增加。41%的儿童出现磨牙磨耗，13%的儿童出现前牙磨耗。未观察到随年龄变化的实际模式。平均最大开口范围为43.7毫米，在23至52毫米之间变化。发现一名女孩开口受限。60%的人发现开口有偏差。26%的人观察到颞下颌关节弹响，28%的人髁突触诊时有疼痛。大多数儿童的症状非常轻微至中度。未发现功能障碍体征与咬合参数之间存在显著相关性。目前的结果并未为这5年期间功能障碍体征的大幅增加提供任何确凿答案。然而，治疗需求较低，不应高估。
