The purpose of this study was to examine how WIRONIT® alloy behaves in phosphate buffer at pH 6.0 (which simulate human saliva) over a relatively long period of time and to establish the type and amount of ions released from the casting alloy. The study also attempted to determine the influence of the time period, during which the casting alloy was exposed to the phosphate buffer at pH 6.0. and 15.8 height) were tested. Release of ions was measured on ten occasions: 1, 2, 3, 4, 5, 6, 7, 14, 21 and 30 days. An analysis of the solution into which samples of the tested alloy were plunged using inductively coupled plasma atomic emission spectrometer (ICP-AES) showed that cobalt (Co), chromium (Cr), iron (Fe), zinc (Zn) and nickel (Ni) ions were released during the month. Co ions were released from the base Co-Cr-Mo alloy in the greatest amount while Fe ions were released in the smallest amount. The results of this study indicate that the time of exposure to the phosphate buffer at pH 6.0 had statistically significant influence (p<0.01) in the release of all detected ions from the Co-Cr-Mo alloy.
