[Oral manifestations of autoimmune diseases with sicca symptoms. Comparative studies of patients with primary and secondary Sjögren syndrome].

Sjögren's syndrome is a chronic autoimmune disease which mainly affects exocrine glands. We present a study where 123 patients with Sjögren's syndrome were examined according to their oral symptoms. A high percentage of patients showed mild or moderate inflammation of the oral mucosa. Remarkable is the high number of extracted teeth in older patients with Sjögren's syndrome. Oral ulcerations and erythema were found only in the group with secondary Sjögren's syndrome and systemic lupus erythematosus.
