Resumo
Elemental mercury is highly toxic and may be absorbed by dental professionals through direct
skin contact or inhalation. The use of mercury in dental amalgam has been a concern of the
academic community for years, for its incorporation is likely to affect vital organ systems.
Several studies have been conducted to address the possible risks of occupational exposure to
mercury vapor in dental offices. The present study aimed to present evidences that mercury is
assimilated by exposed workers through the determination of urinary mercury (HgU) from
dental professionals (n = 91) of public offices in Araguaína (Tocantins, Brazil). This uptake
was verified against samples from unexposed individuals (n = 43), which activities are not
dentistry related. Cold vapor atomic absorption spectrometry (CV-AAS) technique enabled
the subjects’ biological monitoring. Approximately 44.8% (n = 60) of the 134 participants
were aged between 21 and 30 years and were at the beginning of their professional lives;
9.7% (13) of the study participants were men and 90.3% (121) were women. Hg
concentrations in all samples analyzed were within the maximum biological limit set by the World Health Organization (WHO) (<50 μgHg·L−1). HgU concentrations in dental
professionals were within the limits proposed by the Brazilian regulatory standard, Regulatory
Norm-7 (RN-7) (≤35 μgHg·g−1 creatinine). Nevertheless, the average concentration of HgU
was approximately 8 times higher in the potentially exposed group (5.61 μgHg·g−1 creatinine)
than in the unexposed group (0.65 μgHg·g−1 creatinine), highlighting the potential risk of
occupational exposure to mercury.
