Research Abstract |
As the objective of this study was built up to evaluation system of corrosion resistance for dental alloys in oral environments, the influence of proteins in oral environment on resistance of corrosion to fluoride and hydrogen peroxide was systematically discussed. The results indicated that protein in solution and on titanium surface gave titanium alloys to be delayed the discoloration and corrosion. Also, titanium alloys containing chromium had better resistance of corrosion to fluoride and peroxide than other titanium alloys.
