Abstract

The study aims to investigate the effect of fluorinated toothpaste added in Fusayama-Meyer saliva in order to evaluate the electrochemical behavior of 316LSS for dentistry applications.
For electrochemical behavior in situ electrochemical measurements such as: Open circuit potential (OCP), Linear Polarization (PL), Potentiodynamic Polarization (PD) and Electrochemical Impedance Spectroscopy (EIS) were applied. The results show a comparative analysis of the electrochemical behavior and corrosion resistance of 316L-SS in human saliva containing high fluoride toothpaste for dentistry applications. From the electrochemical results it can be concluded that the addition of fluoride toothpaste in Fusayama-Meyer saliva decreases the corrosion resistance of 316L-SS and therefore will reduce the lifetime of dentistry structures or devices.
