Measurement of adsorption of salivary proteins onto soft denture lining materials.
BACKGROUND
The adhesion of Candida albicans to soft liners is a major causative factor in denture stomatitis. It has been suggested that salivary proteins play an important role in this candidal adhesion.


OBJECTIVE
This study measured the adsorption of salivary proteins on soft liners.


METHODS
Five commercial materials and 1 experimental material were immersed in saliva, albumin solution, or milk. Proteins adsorbed on the material surfaces were measured by ATR/FT-IR spectroscopy.


RESULTS
The amount of proteins adsorbed to the 6 materials varied considerably. Protein adsorption was significantly lower in the experimental fluoropolymer and polyphosphazene, and higher in acrylic resin and silicone.


CONCLUSIONS
Different soft liners promote adsorption of varying amounts of protein.
