English abstract
The aim of this study was to correlate clinical diagnoses in temporomandibular disorders patients suffering from pain diagnosed as arthralgia/osteoarthritis or myofascial pain according to the Research Diagnostic Criteria for temporomandibular disorders with findings made on magnetic resonance imaging. The temporomandibular joints of 60 consecutive patients, 41 with arthralgia/osteoarthritis and 19 with myofascial pain, were examined clinically and with magnetic resonance imaging. The most common magnetic resonance imaging findings were disc displacements and structural bone changes, which were found in both pain groups. However, disc displacements were found significantly (p = 0.002) more often in the arthralgia/osteoarthritis group. 104 joints were found to have no clinical diagnosis of disc displacements, but 64 of these joints had findings of disc displacements on magnetic resonance imaging. Joint fluid was found both in the arthralgia/osteoarthritis group (20 patients) and in the myofascial pain group (5 patients). Patients having a combination of disc displacement and joint fluid were significantly (p = 0.047) more common in the arthralgia/osteoarthritis group. In conclusion, the magnetic resonance imaging findings of disc displacement and structural bone changes were common in temporomandibular disorders patients with pain of both myogenous and arthrogenous origin. The clinical diagnoses for subdivision into myogenous and arthrogenous pain groups were not confirmed by magnetic resonance imaging.
