Abstract :
The objective of this work was to demonstrate the effect of fluoride and propolis extract on the corrosion behavior of commercially pur titanium (cp-Ti grade 2) in artificial saliva. The inhibition studies were approved out on cp-Ti as dental implant in Fusayama-Meyer with the propolis extract using potentiodynamic polarization and Electrochemical Impedance Spectroscopy (EIS). Parameters, such as concentration of the inhibitor, time of immersion were varied and optimized. The results showed that either the NaF or the presence of propolis extract in medium saliva had a significant influence on the corrosion rate (Icorr) and polarization resistance (Rp): the Icorr value increased and Rp decreased in medium containing fluoride, but the presence of propolis in media improved the corrosion resistance of this metal.
