Sequential salivary scintigraphy, labial salivary gland biopsy, and measurement of stimulated parotid flow rate were performed in 50 patients suspected of having Sjören's syndrome. The value of these tests in the diagnosis of this disease was compared. Salivary scintigraphy and labial salivary gland biopsy can be used together to disgnose the oral component of Sjören's syndrome. Abnormal salivary scintigraphy correlated with both of the other tests and may be considered optional in the diagnostic evaluation.
