Decisions in DentistryADA Calls for More Transparency, Better Research on Fluoride Safety

A federal science panel has recommended revisions to a National Toxicology Program (NTP) report on the potential associations between fluoride and IQ. The NTP Board of Scientific Counselors unanimously voted to adopt the findings and recommendations of a working group that assessed the report. The systematic literature review, which has been ongoing for several years, aims to summarize the existing research on the relationship between fluoride exposure and neurodevelopmental and cognitive health. The panel identified potential biases in the study and suggested revisions to the meta-analysis based on reviewer comments.

The American Dental Association (ADA) expressed concerns about the report’s methodology and transparency, urging the NTP not to publish it until the concerns are addressed. The draft report claims that higher fluoride exposure is associated with lower IQ in children, but several studies published after the study period ended in 2020 have questioned the methodology used and the strength of the conclusions. The BSC Working Group recommended that the NTP acknowledge potential publication bias and make improvements to the clarity and language used in the report. The recommendations will be forwarded to the NTP director for further consideration.
