Health Risks and Benefits of Fluoride Exposure During Pregnancy and Infancy
Bibliographic record
Abstract
Health authorities have promoted community water fluoridation (CWF) to prevent dental caries for more than 75 years. However, growing evidence has raised questions about the safety of this public health intervention, particularly for young children who are at risk of excess fluoride intake. Divergent opinions about the risk-benefit ratio of CWF have ignited a global debate. The efficacy of topical fluoride in preventing dental caries is strong, whereas contemporary evidence for systemic administration of fluoride is weaker. Inequalities in access to dental care and topical fluorides introduce an additional layer of complexity. This review discusses evidence showing that fluoride ingestion is not essential for caries prevention, offers little benefit to the fetus and young infant, and can cause dental fluorosis and cognitive deficits. In an environment where fluoride is available from multiple sources, community-based administration of systemic fluoride may pose an unfavorable risk-benefit ratio for pregnant women and young children.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
