title: Symptoms of temporomandibular joint osteoarthrosis and internal derangement 30 years after non-surgical treatment.
abstract: To evaluate the long-term condition of temporomandibular joints (TMJs) affected by osteoarthrosis and internal derangement, 99 patients treated non-surgically between 1958 and 1962 were recalled for follow-up. The patients, 16 men and 83 women (mean age 58.2 years) with either reducing or permanent disk displacement, were submitted to a structured interview concerning previous treatment, masticatory function, and the presence of symptoms of osteoarthrosis and internal derangement of the masticatory system, and of complaints of the musculoskeletal system in general. A control group, consisting of eight men and 27 women (mean age 58.9 years) without complaints of the masticatory system, matching the patient group for sex, age and state of dentition, was included in the study to avoid simply documenting age-related joint conditions. Satisfaction with the treatment outcome was high. Chewing ability of the the patients did not differ from that of the controls, although patients more often expected pain and difficulty with opening the mouth wide. The main TMJ symptoms of the patients had decreased significantly; patients reported joint noises more often than controls. It is concluded that, despite some persisting symptoms, the non-surgical treatment approach of TMJ osteoarthrosis and internal derangement provides long-lasting satisfactory subjective results and is well-accepted by the patients.
