English summary

Several general diseases are associated with temporomandibular disorders

The aim of this literature review was to evaluate the association of temporomandibular disorders (TMD) and certain general diseases and to discuss the possible mechanisms related to the association. Based on the literature, the general diseases chosen were headache, migraine, depression, fibromyalgia, rheumatoid arthritis, juvenile rheumatoid arthritis, degenerative joint disease (osteoarthritis) and thyroid disease.

TMD refers to pain and/or dysfunction of the temporomandibular joints (TMJs), masticatory muscles and associated structures. The most common symptoms of TMD are pain in the jaw and masticatory muscles, limited jaw movements, locking of the jaw and TMJ sounds. In addition, many other pain symptoms or diseases may occur in patients with TMD, of which the most common are facial and ear pain, comorbid pain symptoms, including neck, shoulder and/or back pain, and headache or fibromyalgia.

TMD symptoms most commonly occur at the age of 35–50 years. The peak occurrence of TMD is seen between ages 20 and 50 years, and it affects more females than males.

Many general diseases have been shown to be associated with TMD. The most common comorbidity is with headache and migraine. Diagnosed depression has been found in every fifth of the TMD patients. Fibromyalgia may predispose patients to TMD; most of the patients with fibromyalgia have TMD symptoms. Rheumatic arthritis may cause changes in TMJs and both juvenile rheumatoid arthritis and adult rheumatoid arthritis patients have more TMD than patients without rheumatoid arthritis.

Most of the associations between general diseases and TMD may be linked to central sensitization. These associations should be considered when treating patients with TMD.
