Risks of Dental Amalgam in Children—Reply

Since this article does not have an abstract, we have provided the first 134 words of the full text and any section headings.

In Reply: Our article did not state that there is no evidence of an association between exposure to mercury vapor released from amalgams and human health risks. To paraphrase Paracelsus,1 it is the dose that makes the poison. We reported that, at the levels of amalgam exposure experienced by the children enrolled in the New England Children's Amalgam Trial, we did not observe any adverse effects on neuropsychological or renal function.

The outcomes reported were those identified at the outset of the trial as the primary end points. Drs Pigatto and Meroni are correct that, for a subgroup of the children who participated in the trial, measurements of immune responsiveness were carried out.2 The results of treatment group comparisons of these end points will be reported when they are available.

Financial Disclosures: None reported.
