Our aims were to study the prevalence of abnormal radiographic findings in mandibular condyles and the possible association between such findings and clinical signs and symptoms of temporomandibular dysfunction (TMD) and dental state. Two cohorts of 70-year-old people, 384 men and 484 women, living in Göteborg, Sweden, participated in the study. The first cohort was examined in 1972 and the other one in 1992. Besides a functional and clinical examination, a questionnaire on TMD and panoramic radiography were included. A deviation from the normal appearance of one or both condyles was found in 26% of the subjects (17% of the condyles). There was no significant difference in this respect between the two cohorts. There were in general only minor and no statistically significant differences between those with normal and deviating condylar findings with regard to various TMD signs and symptoms. The subjects in Eichner group A (with dental support in all zones) showed a slightly lower frequency of abnormal radiographic condylar findings (22%) than those in groups B (reduced dental support) and C (edentulous in one or both jaws; both B and C, 28%). It is concluded that abnormal radiographic condylar findings in these elderly people were not at all or only weakly correlated with signs and symptoms of TMD and dental status.
我们的目的是研究下颌髁突影像学异常表现的患病率，以及这些表现与颞下颌关节紊乱病（TMD）的临床体征和症状及牙齿状况之间可能存在的关联。居住在瑞典哥德堡的两组70岁人群（384名男性和484名女性）参与了该研究。第一组在1972年接受检查，另一组在1992年接受检查。除了进行功能和临床检查外，还纳入了一份关于TMD的问卷和全景X线摄影检查。在26%的受试者中发现一个或两个髁突的外观偏离正常（占髁突的17%）。在这方面，两组之间没有显著差异。总体而言，在各种TMD体征和症状方面，髁突表现正常和异常的受试者之间只有微小差异，且无统计学意义。艾希纳A组（所有区域均有牙齿支持）的受试者影像学髁突异常表现的频率（22%）略低于B组（牙齿支持减少）和C组（一侧或双侧无牙；B组和C组均为28%）。得出的结论是，这些老年人影像学髁突异常表现与TMD体征和症状及牙齿状况之间要么根本没有关联，要么只有微弱关联。
