Abstract

Saliva at rest separates in a bulk solution and a protein layer on top. The layer has been characterized ellipsometrically giving its thickness and density. Rheologically the layer and bulk were studied separately with linear and non-linear methods: harmonic shear experiments and flow curves. Thus a rheological framework resulted which was used for the study of existing saliva substitutes and the development of Theologically improved substitutes. The improvement of saliva substitutes was searched in mixtures of mucins and bovine serum albumin. These mixtures were studied with the same rheological means as the saliva samples. It turns out that mixtures exist that mimic saliva Theologically quite well.
