Jaw condition may be linked to psoriatic arthritis
Investigators have explored the relationship between psoriasis and temporomandibular joint function. They noted that the systemic inflammation caused by the dermatologic condition may impact musculoskeletal health; however, current data on the correlation is limited.
In a cross-sectional study published in Skin Health and Disease, the investigators analyzed the associations between sleep quality and temporomandibular joint function among more than 100 participants with psoriasis and age- and sex-matched controls. They then assessed the correlations on the basis of psoriatic arthritis status and systemic treatment type — including interleukin-17/23-targeted biologic therapy; nonbiologic therapy with methotrexate, acitretin or ciclosporin; or no systemic therapy.
The investigators found that although there were no statistically significant differences in temporomandibular joint function limitations between the participants with psoriasis and controls, those with psoriatic arthritis had higher scores compared with controls. In addition, the participants who were receiving biologic therapy had better sleep quality scores and lower psoriasis severity similar to those of controls.
The findings revealed that cutaneous disease may be directly related to sleep quality in patients with psoriasis, whereas psoriatic arthritis may be linked to temporomandibular joint function.
