Abstract
Objectives: Dental amalgam consists of approximately 50% mercury, which is a toxic element. Since children are more at risk for mercury toxicity, we aimed to assess the association between dental amalgam filling and urinary mercury concentration in children.
Methods: Four hundred eighty four elementary school children in grades 1∼4 were conveniently recruited from two schools located in Daegu city, Korea. Oral examination were conducted to obtain dental caries experience states using the full term for DFS index, number of amalgam filling surfaces and the type of filling materials. A questionnaire was used to collect information about general characteristics and the frequencies of tooth brushing, gum chewing and fish/seafood consumption. The statistical analysis was done using the SPSS 18.0 program.
Results: The mean urinary mercury concentration in children having eight amalgam surfaces was highest at the level 4.26μg/L. The level of urinary mercury in children with 6∼10 amalgam fillings and more than 11 amalgam surfaces was significantly higher than in those having no amalgam after adjusting for other covariates.
Conclusions: Children exposed to more dental amalgam may be prone to an increased urinary mercury level.
