    Abstract:
    Sialographic follow-up studies of 36 cases of Sjögren's syndrome (SS) were performed with the duration of 5-72 months (mean 25 months). Three groups were divided according to the intenational criteria: secondary group, 14 cases (xerophthalmia, or/and xerostomia, and connective tissue diseases), primary group, 14 cases (xerostomia and xerophthalmia), and possible group, 8 cases (xerophthalmia or xerostomia only). Sialographic findings at follow-up examination included (1) delayed evacuation, which may occur as early as 5 months later; (2) increased punctate sialectasis; (3) decreased punctate sialectasis with globular increase; (4) Punctate, globular, and cavity sialectasis with radiolucent sialolith; and (5) centripetal atrophy. The cases with secondary and possible SS without xerostomia demonstrated little involvement of the parotid gland, without sialectasis. But sialodochitis was shown when radiolucent sialolith formed. The stimulated whole salivary flow rate (SWSFR) was closely related to sialographic appearance, i.e., the cases with lower value of SWSFR showed more sialectasis sialographically, but with higher SWSFR value, and less sialectasis.
