Contamination of the zirconia surface by components of mixed saliva and its control by X-ray photoelectron spectroscopy. Part 1. Untreated surface (mucin model)
INTRODUCTION. Zirconium dioxide (ZrO 2 ) is among the most widely used materials for fixed dental prostheses, and the reliability of adhesive luting largely depends on surface cleanliness. Contact of the framework with mixed saliva during try-in results in adsorption of organic components that reduces bond strength...
