AimsThe aim of this study was to investigate the prevalence of temporomandibular disorders (TMD) in patients with primary Sjögren syndrome (1 degree SS), analyze the impact of the disease on mandibular function, and assess psychosocial distress.MethodsSixty-three subjects, 60 women and 3 men, participated in the study; 21 1 degree SS patients were compared with age-matched and gender-matched groups of TMD subjects and controls. Patients were examined according to the Research Diagnostic Criteria for Temporomandibular Disorders.ResultsResults showed that the subjective, clinical, and radiographic signs of TMD are not more common in patients with 1 degree SS than in controls. The impact of the autoimmune disease on mandibular function, e.g., speech and chewing ability, revealed limitations in oral functioning similar to those in patients with TMD pain.ConclusionBoth 1 degree SS and chronic TMD may be associated with appreciable physical discomfort and psychosocial dysfunction. However, the underlying mechanisms of the oral dysfunction of 1 degree SS and TMD are quite different and essentially unrelated.
