This study was proposed to investigate the release of element from five brands of commercially available dental casting alloys. Finished and polished specimens of dental casting alloys (five brands Cr, Ni, Cu, Mo and Ag) were washed using sterilized distilled water, then dried and again soaked in alcohol to disinfect them for 20 minutes. Each specimen of casting alloys was accounted for 2 ml of simulating solvent. The sealed vials were kept in shaker water bath at different temperature i.e. 4 0C, 37 0C, 60 0C for a period of 24 hours and 7 days accordingly. Elemental release from five brands of non–precious dental casting alloys was assessed at different variables using the AAS. Continuous variables will be presented as mean and SD. Quantitative variables will be compared using one–way ANOVA test between three groups and paired t test will be used for comparison of pair at day 1 and day 7. At 1–day temperature had a significant association on concentration of Cr, Ni and Mo.  At 7–day temperature had a significant association with concentration of Cu, Cr, Ni and Mo. pH had no association with concentration of non–precious alloys. The concentration of Cu, Cr, Ni and Mo on 7 days was significantly higher as compared to that on day 1. No statistically significant difference in concentration of Ag was seen between 1 day and 7 days. Time had a significant effect on concentration of trace elements. An overview of the present study dictates that there is definite release of elements from dental casting alloys.
