In this paper corrosion resistance of experimental dental Co-Cr-X (X = Mo, Ni) alloys, high purity titanium and Ag-amalgam was studied in Ringer’s solution. On the basis of electrochemical measurements, the relevant indicator of general corrosion jcorr, which is used for ranking of materials, was determined. It was found that commercial alloy Wironit® is the most stable material followed by pure titanium, Co-Cr-Mo and Co-Cr-Ni alloys, while amalgam showed the lowest resistance in the experimental conditions of model oral cavity medium.U ovom radu ispitana je korozijska otpornost eksperimentalnih zubnih Co-Cr-X (X = Mo, Ni) slitina, titana i Ag-amalgama u Ringerovoj otopini. Na osnovi elektrokemijskih mjerenja određen je relevantni pokazatelj opće korozije jkor, koji se koristi za rangiranje materijala. Pokazalo se, da je korozijski najstabilnija komercijalna slitina Wironit®, koju slijede čisti titan, te Co-Cr-Mo i Co-Cr-Ni slitine, dok se amalgam pokazao najmanje otpornim u ispitnim uvjetima koji simuliraju medij usne šupljine
