Abstract
Previous studies have suggested that exposure to Ni from Ni-Cr alloys can affect the human body through oxidative stress. The present study discusses the effect of nickel from Ni-Cr alloy prostheses on the formation of DNA Adduct 8-Hydroxy-2′-Deoxyguanosine (8-OHdG), evaluated based on creatinine and 8-OHdG concentrations in urine, determined with LC-MS/MS, for a Ni-Cr alloy user group and a never-user control group. The mean creatinine and 8-OHdG concentrations were not significantly different between the test groups, although highest levels were observed for the in the Ni-Cr user group. It is suggested that samples with relatively high creatinine and/or 8-OHdG levels are further studied in more detail for stability of concentrations and for the effect of contributing factors.
