—Dental laboratory technicians may be exposed to metal alloys that are used in the production of crowns, bridges and removable partial dentures. The aim of this study was to assess whether dental technicians are occupationally exposed to Cobalt, Nickel and Chromium by analyzing the concentration of Cobalt, Nickel and Chromium in the blood level and to investigate the effects of occupational environmental controls associated with dental prostheses production in dental laboratories in East Java Indonesia. Result found shows that the concentration of Cobalt, Nickel and Chromium in the blood level of dental technicians are higher than the certified reference material level recommended. The concentration of Cobalt, Nickel and Chromium in the dental technicians’ blood level are 27 μg/L, 37 μg/L and 117 μg/L respectively. Although 50% of dental laboratories surveyed had ventilator and air dust respirator, almost all of the technicians did not do personal occupational environmental controls correctly.
—Cobalt, Chromium, exposure, Nickel, protection control.
