We evaluated a simple, cheap and non-invasive diagnostic test for xero
stomia : the ''RCS (salivary cotton roll) - test''. We studied 33 pati
ents suffering from xerostomia and 33 asymptomatic patients. The RCS-t
est was compared to salivary scintigraphy. Our results show that the R
CS-test can easily be performed and is useful in detecting sicca syndr
ome or in diagnosing Sjogren's syndrome.
