Sumario:AIM: The aim of this study was to quantitatively estimate the concentration of ion release from recasted base metal alloys in various pH conditions using atomic absorption spectroscopy (AAS). MATERIALS AND METHODS: Specimens of commercially available dental casting alloys (cobalt [Co]-chromium [Cr] and nickel [Ni]- chromium [Cr]) were prepared using lost-wax casting techniques and were stored in the test solution for 1 week and 4 weeks, and ions released during chemical corrosion were detected using AAS. RESULTS: An increase in the quantity of ion release was observed with recasting. These changes were higher after twice recasting in Ni-Cr alloy.
