Craniomandibular disorders in psoriatic arthritis: Correlations between subjective symptoms, clinical signs, and radiographic changes

Abstract

One hundred and ten patients with psoriatic arthritis (PA group) and 110 individually matched control subjects (C group) without general joint or skin disease were studied to determine correlations between radiographic changes, detected on orthopantomography, in the condyle of the temporomandibular joint and subjective symptoms and clinical signs of craniomandibular (CM) disorders. In the PA group there was a correlation, not found in the C group, between the radiographic changes, especially erosions, and subjective symptoms and clinical signs of CM disorders. The correlations found indicate that in PA subjective symptoms, clinical signs, and radiographic changes in the stomatognathic system are mainly caused by the systemic joint disease.

The prevalence of temporomandibular disorders in patients with psoriasis with or without psoriatic arthritis

“…There is a lack of data on prevalence of TMD symptoms in psoriasis and in PA. Therefore, it is only possible to compare with the present findings of studies by Könönen (29–32, 40). This present study reported that 29·4% of patients with psoriasis without PA had TMD symptoms, which is similar to findings of Könönen (28%) (31).…”

“…To date, only about 35 reported cases of PA affecting the TMJ have been reported in the literature (Table 1) (17–28). However, Könönen have investigated the subjective, clinical, and radiographic features of temporomandibular disorders (TMD) in patients with PA and have reported that involvement of the TMD may be common (29–32).…”

Psoriatic arthritis of the temporomandibular joint – a surgical alternative to treating a medical problem

“…Involvement of the TMJ in PA had traditionally been thought of as relatively rare with few (less than 40) cases being reported. Recent evidence from Könönen 8 and Dervis 9 suggest that signs and symptoms of TMDs could be more common in patients with PA than has previously been thought. Dervis found the prevalence of TMDs on clinical examination of PA patients to be 60%, a figure that is similar to that found by Salonen et al 10 .…”

Successful treatment with multiple intra‐articular injections of infliximab in a patient with psoriatic arthritis

“…High synovial fluid levels of TNFa have been associated with temporomandibular joint (TMJ) pain (2) and high plasma levels of TNFa have been associated with radiographic signs of TMJ bone tissue destruction as well as anterior open bite, which is a clinical sign of cartilage and bone tissue destruction in the TMJ (3,4). Clinical and radiographic involvement of the TMJ can be expected to occur in about 50% of patients with PsA (5).…”
