Introduction and objective:
Temporomandibular disorders (TMD) are currently among the most commonly diagnosed disorders of the stomatognathic system. They are related to the overall condition of temporomandibular joints (TMJ). In recent years, there have been an increasing number of reports related to clinical patients suffering from stomatognathic disorders accompanying psoriasis. The aim of the study is to assess the incidence and identify the types of temporomandibular disorders in patients diagnosed with psoriasis.

Material and methods:
The study was conducted in a group of 64 patients (32 men and 32 women) treated for psoriasis at the Med-Laser Non-Public Health Care Centre in Lublin. The study was conducted in two stages. The first stage entailed the use of a normalised questionnaire in which the patients were surveyed regarding the incidence of TMD symptoms. The survey questions were prepared on the basis of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/ TMD). The second stage entailed the performance of clinical examinations in accordance with the RDC/TMD classification guidelines.

The survey revealed that over 1/3 of the subjects experienced at least one type of TMJ disfunction included in the RDC/TMC questionnaire.

Psoriasis patients are most often classified into class IIa TMD according to RDC / TMD diagnoses. For this reason, patients reporting such symptoms should be referred for full diagnostic stomatological examination for the possible presence of temporomandibular disorders. The inclusion of screening for TMD symptoms should be considered in patients treated for psoriasis
