The prevalence of clinical signs of temporomandibular disorders in 76-, 81-, and 86-year-old subjects living in Helsinki, Finland, were studied, using Helkimo's clinical dysfunction index. In percentage distribution, clinically symptom-free subjects (Di 0) constituted 20% of all those examined, and by percentage the largest group of subjects without signs was that of the oldest men (47%). Women had a higher prevalence of signs of temporomandibular disorders, and only 15% were clinically symptom-free. Four per cent of all those examined had severe symptoms. The commonest signs were impaired range of movement of the mandible and impaired function of the temporomandibular joint.
利用赫尔基莫临床功能指数，对居住在芬兰赫尔辛基的76岁、81岁和86岁受试者颞下颌关节紊乱临床体征的患病率进行了研究。在百分比分布中，临床无症状受试者（Di 0）占所有受检者的20%，且按百分比计算，无体征受试者中占比最大的是年龄最大的男性组（47%）。女性颞下颌关节紊乱体征的患病率更高，只有15%的女性临床无症状。所有受检者中有4%有严重症状。最常见的体征是下颌运动范围受限和颞下颌关节功能受损。
