Abstract

Abstract

Thin sections (90–100 nm) of flash-frozen human saliva fractions and whole saliva were examined by transmission electron microscopy. Inside the major filamentous structural components numerous ultrastructural details were observed, especially for whole saliva and submandibular/sublingual fractions. An outer reticulated zone believed to contain the major salivary glycoproteins surrounded an inner core consisting of a continuous, more electron dense phase with multiple vacuoles and granules of different sizes, shapes, and electron densities. The observed structures suggest a complex microarchitectural model for whole saliva.
