从哥德堡老年学人群研究中随机选出的 35 名 90 岁受试者（H-70）接受了咀嚼系统功能和功能障碍的检查。这些方法包括问卷、临床检查以及记录中切牙区域测量的咬合力耐力和最大咬合力。 40% 的人无牙，29% 的人部分无牙且佩戴可摘义齿，而其他人则有齿但未佩戴可摘义齿。颞下颌关节紊乱的体征和症状大多轻微且罕见，但 69% 的受试者出现颞下颌关节捻发音。最大咬合力一般较低（平均 94 N），但个体差异很大（范围 10 至 410 N）。咬合力耐力也变化很大（平均 72 秒，范围 10 至 205 秒）。 35 名受试者中没有一人表示咀嚼能力较差，但有 2 名受试者表示无法咀嚼各种食物。尽管咬合力有所减弱，这组 90 岁老人仍认为自己的咀嚼能力良好，而且大多数人没有严重的颞下颌疾病体征和症状。
A group of 35 90-year old subjects, randomly selected from the gerontologic population study in Göteborg (H-70), were examined with respect to function and dysfunction of the masticatory system. The methods included a questionnaire, clinical examination and recording of bite force endurance and maximal bite force, measured in the central incisor region. Forty percent were edentulous, 29% were partially edentulous and wore a removable denture, while the others were dentate without removable prostheses. Signs and symptoms of temporomandibular disorders were mostly mild and infrequent, except TMJ crepitation which was recorded in 69% of the subjects. Maximal bite force was in general low (mean 94 N) but showed a great individual variation (range 10 to 410 N). Bite force endurance was also very variable (mean 72 s, range 10 to 205 s). None of the 35 subjects reported poor masticatory ability, but 2 said they could not chew all kinds of food. In spite of a reduced bite force this group of 90-year olds considered their masticatory ability as good and most of them had no severe signs and symptoms of temporomandibular disorders.
