Abstract

Background: High concentrations of Co, Ni, and Cr in the blood serum of dental technicians are strongly associated with free radical formation. It has highly reactive properties that can cause further oxidation of molecule in the vicinity. Purpose: This study intended to investigate whether the Dental Technician occupational exposure of Co, Ni and Cr, could contribute to the high incidence of cancer. Methods: This was a cross-sectional study to dental technicians, performed after acccepting ethical clearance. Blood was sampled in 3 examinations for Co, Ni, Cr using Atomic Absorbance Spectrophotometry (AAS), MDA was examined with TBARS test, also 8 OHdG and wildtype p53 proteins determined by ELISA method. Results: Comparative statistical analysis, showing a significant difference (p < 0.05) between levels of Co, Ni, and Cr in exposed groups to the control group. But, not all variables was proven to be positively correlated, only with Cr, and Co, and negatively correlated with wild-type p53. Conclusion: MDA,8-OHdG and wildtype p53 can be used as genotoxic biomarkers in the metal exposed group, since they can accurately reflect the degree of Oxidative damage.
