Epithelial senescence predicts salivary dysfunction in Sjögren disease and glandular integrity defines residual capacity.
To investigate whether structural integrity and epithelial senescence in the submandibular gland (SMG) predict longitudinal salivary gland dysfunction in Sjögren disease (SjD). This retrospective cohort study analysed 51 anti-SSA-positive SjD patients who underwent US-guide…
