The National Toxicology Program

This section is dedicated to the National Toxicology Program’s (NTP) long involvement with the issue of fluoride's toxicity. The NTP is the scientific research arm for U.S. regulatory agencies. It comes under the aegis of the National Institute of Environmental Health Sciences (NIEHS). The NIEHS, in turn, comes under the umbrella of the National Institutes of Health (NIH). -Updated May 2, 2023 (EC).

May 4, 2023, Board of Scientific Counselors meeting

On May 4, 2023, the NTP’s Board of Scientific Counselors (BSC) held a public meeting, via webcast, to present the results of its review of NTP’s fluoride Monograph and Meta-Analysis and to hear public oral comments. Written comments from the public were solicited and the deadline date was April 28. The documents under the BSC’s consideration are available here. A list of the members of the BSC are here.  The BSC voted unanimously to accept the recommendations of their working group in support of the work performed by the NTP after resolving a statistical error on IQ that Paul Connett commented on (see comments below). The full webcast, approximately 3 hours long, is available below:

The Charge of the BSC on NTP’s work on fluoride’s neurotoxicity:

The charge of the Board of Scientific Counselors (BSC) was to evaluate the adequacy of NTP* responses to external peer review and/or federal agency comments received during the development of the State of the Science Monograph and the Meta-Analysis Manuscript.

The BSC will not provide independent peer review of the State of the Science Monograph or Meta-Analysis Manuscript.

The BSC may offer perspectives and suggest revisions that might improve the quality of either document.

*NTP Staff within the Division of Translational Toxicology, National Institute of Environmental Health Sciences developed the State of the Science Monograph and the Meta-Analysis Manuscript on behalf of the NTP.
