Surface Reaction of Titanium Oxide Film to Fluoride and Hydrogen Peroxide in Simulated Oral Environment

Abstract:

When titanium and titanium alloys are used in prosthodontic devices, exposure to the oral environment may result in discoloration or corrosion. This phenomenon may be due to fluoride, found in prophylactic agents, or peroxide, which is either produced by inflammatory cells or present in denture cleaning agents. The aims of this study were to clarify the process of discoloration or corrosion of titanium in an oral environment, and investigate the reaction of surface titanium oxide to fluoride and hydrogen peroxide by analysis of electrochemical behavior and X-ray photoelectron spectroscopy. Surface oxide film on commercially pure titanium (CP-Ti) in fluoride-containing solution was dissolved and corroded. In the peroxide-containing solution, a gradual development and thickening of the surface oxide film with subsequent discoloration of the titanium was observed
