Measurement of adsorption of salivary proteins onto soft denture lining materials.

摘要

STATEMENT OF PROBLEM: 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. PURPOSE: This study measured the adsorption of salivary proteins on soft liners. MATERIAL AND 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. CONCLUSION: Different soft liners promote adsorption of varying amounts of protein.
