Magnetic resonance imaging (MRI) is the newest and perhaps the most available medical imaging technology. No more available research covering the effects of MRI on structure and physical properties of dental alloys. For this reason, the effect of MRI on structure, Vickers hardness, roughness and electrochemical corrosion behavior of Protechno® -N(Ni=63%,Cr=24.6%,Mo=10.77%, Si=1.50%,Mn=0.03%andC=0.01%) dental alloy has been studied. The results showthat,Vickers hardness, roughness parameters, corrosion resistance and corrosion rate of Protechno® -N alloy changed after exposure to MRI.
