Abstract
OBJECTIVES: To test the hypothesis that the outcome of temporomandibular disorders (TMD) is not influenced by condylar position, asymmetry, angle or structural bone changes. METHODS: Eighty consecutive patients (60 women, 20 men) with an age range of 6-81 years, referred to the Department of Stomatognathic Physiology, were included in the study. The patients were clinically and radiologically examined before and at least 1 year after treatment. RESULTS: The most common clinical diagnoses among the patients were TMD with a neuromuscular background in 35% and osteoarthritis in 21%. Seventy-two per cent of the patients were symptom-free or better, 24% unchanged and 1% worse 1 year or more after treatment. After treatment the bone structure of the TMJ was unchanged in 83% of the patients, in 12% erosions healed and in 5% erosions developed. Almost all patients had some degree of condylar displacement on tomography before treatment. In the majority the condylar position was unchanged after treatment. CONCLUSION: No single radiographic finding was found to be related to the treatment outcome and therefore plain radiography has a minor role in the management of TMD.
