Description
The aim of the current study is to examine the various factors, which contribute to high levels of mercury (Hg) in the hair of Lebanese dentists. The survey, which was carried out on ninety-nine dentists in the greater Beirut area, included a structured questionnaire designed to provide information about the parameters that influenced their occupational exposure to Hg. These included: precautionary measures, dental fillings, work habits and lifestyle of the tested dentists. The study showed that two of the four investigated precautionary measures had a significant effect on Hg level. The results revealed that, at the 95% confidence levels, Hg concentration in hair was significantly lower among the dentists who always used gloves and masks. Multiple regression analysis showed that the use of masks (P=0.055) had significant effects on mercury accumulation in hair. In addition, dentists who saw more than eight patients per day had marginally higher mercury levels in their hair than those who did not. Since it was shown that precautionary measures could limit exposure to Hg concentration, then the use of protective measures needs to be emphasized. © 2002 Elsevier Science B.V. All rights reserved.
