The friction coefficients for parotid and submandibular-sublingual salivas of 7 subjects were measured. At the load and speeds used, the lubricatory properties of the secretions followed the McKee-Petroff's curve. The friction coefficients for both secretions approximated those reported for boundary and thin film lubrication.
