The purpose of this 20-year follow-up study was to assess whether pronounced morphologic traits of malocclusion, persisting from adolescence to about 35 years of age, imply an increased risk of persistent and severe mandibular dysfunction. In 1965-66 malocclusion was recorded in 176 adolescents; in 1981 these persons responded to a questionnaire concerning symptoms of functional disorders, and in 1986-87 malocclusion and signs of dysfunction were registered. Highly significant associations were observed between some of the self-reported symptoms and the signs registered 5-6 years later. Spearman correlation coefficients between the persistent traits of malocclusion, occurring at both examinations, and the signs of mandibular dysfunction were low in general. No association was found between the most severe and persistent functional disorders and any particular malocclusion. It is concluded that orthodontic screening of morphologic malocclusion in childhood would seem of limited value in attempts to predict mandibular dysfunction in adulthood.
这项为期20年的随访研究旨在评估从青春期到35岁左右持续存在的明显错颌畸形形态特征是否意味着持续性和严重下颌功能障碍的风险增加。1965 - 1966年记录了176名青少年的错颌畸形情况；1981年这些人对一份关于功能障碍症状的问卷做出了回应，1986 - 1987年对错颌畸形和功能障碍体征进行了登记。在一些自我报告的症状与5 - 6年后登记的体征之间观察到高度显著的关联。两次检查中均出现的错颌畸形持续性特征与下颌功能障碍体征之间的斯皮尔曼相关系数总体较低。在最严重和持续的功能障碍与任何特定错颌畸形之间未发现关联。结论是，儿童期形态性错颌畸形的正畸筛查在预测成年期下颌功能障碍方面似乎价值有限。
