Urinary mercury concentrations associated with dental restorations in adult women aged 16–49 years: United States, 1999–2000

摘要

Background: Mercury amalgam dental restorations have been used by dentists since the mid 19th century and issues on safety continue to be periodically debated within the scientific and public health communities. Previous studies have reported a positive association between urine mercury levels and the number of dental amalgams, but this relation has never been described in a nationally representative sample in the United States.
