Subjective symptoms from the stomatognathic system in patients with psoriatic arthritis

One hundred and ten patients with psoriatic arthritis (PA group) and 110 individuals (C group) selected on the basis of sex, age, and dentition to match the PA group answered a questionnaire concerning subjective symptoms of craniomandibular (CM) disorders and general joint symptoms. Patients with PA had more frequent and more severe subjective symptoms than individuals in the C group, such as pain in the temporomandibular joints (TMJ) and cheeks and morning stiffness/tiredness in the jaws. In the PA group the number and severity of subjective symptoms of CM disorders correlated with the number of joints affected by PA and the severity of PA. Pain in the TMJ (reported by 32%) correlated with both the number of joints affected by PA and the severity of PA.
