摘要: Several European countries have guidelines suggesting that women should not receive mercury-containing dental amalgam fillings during pregnancy. One concern raised by several studies is mercury exposure pregnancy may lead to decreased birth weight. A population-based, case-control study was designed investigate whether placement of in 1993–2000 increased the lowbirth-weight risk. Cases and controls were sampled from enrollees a insurance plan with live singleton births Washington State; 1,117 low-birth-weight infants (<2,500 g) compared random sample 4,468 weighing 2,500 g or more. The results indicated 13% dentally insured population had one more restorative procedures that, regardless chemical composition, did increase risk (odds ratio 5 0.96, 95% confidence interval: 0.88, 1.05). 4.9% (n 249) who at least filling an for infant 0.75, 0.45, 1.26) neither 4–11 placed 1.00, 0.27, 3.68).
