Sjögrens syndrome is a common autoimmune rheumatic disease. The most common symptoms of Sjögrens syndrome are extreme tiredness, along with dry eyes (keratoconjunctivitis sicca) and dry mouth (xerostomia). Saliva plays an essential role in numerous functions of the mouth. Xerostomia can be caused by medications, chronic diseases like Sjögrens syndrome, and medical treatments, such as radiation therapy and bone marrow transplant. Xerostomia can eventually lead to difficulty in swallowing, severe and progressive tooth decay, or oral infections. Despite having excellent oral hygiene, individuals with Sjögrens syndrome have elevated levels of dental caries, along with the loss of many teeth, early in the disease. Sjögrens syndrome alters the protein profile and brings about a change in the composition of saliva. There is an increase in the levels of lactoferrin, β2-microglobulin, sodium, lysozyme C, and cystatin C, and a decrease in salivary amylase and carbonic anhydrase. Up to 90% of individuals with Sjögrens syndrome have antibodies targeting the Ro 60 and La autoantigens. Natural aging, regardless of Sjögrens syndrome, is also another factor that brings about a significant change in the composition of saliva. The most prevailing cause of xerostomia in elderly persons is the use of anticholinergic medications. Currently, there is no cure for Sjögrens syndrome, and treatment is mainly palliative.
