- Abstract
- OObbjjeeccttiivveess: The aim of this study was to evaluate the level of urinary mercury and analyze which factors would affect urinary mercury concentration among dental hygienists in dental clinics.
MMeetthhooddss: This study conducted by questionnaire and detection of urinary mercury concentration of 268 dental hygienists working in dental clinics from July to August of 2009. Data collected from two hundred and thirty-five dental hygienists were analyzed by the geometric mean (GM). Analytical results of urine samples with less than 0.3 g creatinine/L and greater than 3g creatinine/L were excluded from statistical analysis.
RReessuullttss: Urinary mercury concentration of 235 dental hygienists showed the geometric distribution. The arithmetic and geometric means of urinary mercury concentration were 0.996㎍/g creatinine and 0.755㎍/g creatinine, respectively.
From multiple regression analysis, the number of amalgam filling, the consumption frequency of raw fish and the number of amalgam handling in current workplace was revealed as increasing factors of urinary mercury concentration.
CCoonncclluussiioonnss: The level of urinary mercury in dental hygienists was higher than in general Korean population. The number of amalgam filling, the consumption frequency of raw fish and the number of amalgam handling in current workplace was revealed as increasing factors of urinary mercury concentration. Therefore using resin materials instead of amalgam in dental clinics is highly desirable.
