The aim of the study is to evaluate olfactory, taste (intra-nasal and oral) trigeminal functions in patients with Sjogren's syndrome compared to patients without sicca syndrome.
Sjögren syndrome is an autoimmune disease, responsible for xerostomia and xerophthalmia. Other organs and tissues can be affected: the skin, vaginal and nasal mucous membranes. As well, olfactory disorders have been also described in Sjögren syndrome.~Xerostomia often causes significant functional impairment of taste function. Impairment of taste function has been poorly evaluated in Sjögren syndrome like olfactory or (intra-nasal and oral) trigeminal disorders.
