Abstract
The purpose of this research is to make appropriate chairside environment by warning the danger of mercury and by reducing incautious handling of mercury which can pollute the air of dental clinic.
Forty-three dental hygienists at work were chosen as a study group, who have not exposed to extra large amount of mercury, and 21 women who were not dental hygienists and had never used mercury-materials as a control group. About 1 g of hair from the occipital region was collected from each subject and mercury content was analyzered by Gold Amalgam Method using Mercury Analyzer(NIG Nippon Instrument Co.)
The obtained results were as follows;
1. The mercury contents in hair were 1.02 ± 0.76 ppm in dental hygienists and 0.51 ± 0.17 ppm in control women. The difference of mercury contents was statistically significant between two groups(P < 0.05).
2. The mercury contents in hair were 0.94 ± 0.82 ppm in dental hygienists who had been worked in dental clinic for 1 or 3 years and 1.06 ± 0.74 ppm in those who had been worked for more than 4 years. The difference of mercury contents was statistically non-significant between two groups(P > 0.05).
3. The mercury contents in hair were 0.81 ± 0.45 ppm in dental hygienists who handled less than 10 mean tablets of amalgam alloy a day and 1.37 ± 1.02 ppm in those who handled more than 10 mean tablets of amalgam alloy a day. The difference of mercury contents was statistically significant between two groups (P < 0.05).
