Salivary scanning in rheumatoid arthritis with sicca syndrome.
Forty-nine patients were studied prospectively by salivary scanning to assess the value of this investigation in possible Sjögren's syndrome (SS). Twenty-three had rheumatoid arthritis (RA) with sicca symptoms and a positive Schirmer's test. Fifteen had RA with no sicca symptoms and a negative Schirmer's test. Eleven had osteoarthrosis (OA) with no sicca symptoms and a negative Schirmer's test. Scanning differentiated only poorly between the three groups. We conclude that it has only limited application in the diagnosis of SS associated with RA.
