Are ultrasonographic scoring systems of the salivary gland in primary Sjögren’s syndrome suitable for examination of Type2 diabetes mellitus patients with sicca?

This study demonstrated that major salivary gland involvement was more severe and correlated with disease duration, and submandibular gland was dominantly affected in pSS. Contrarily, in DM patients, salivary gland involvement was milder, parotid dominant and related to level of dryness and HbA1C, rather than disease duration when compared to pSS.
