Fluoride-containing dental care products (mainly fluoride toothpaste; one study also included fluoride varnish) vs Dietary fluoride sources (drinking water, beverages, food): Contribution of dental care products to total daily fluoride intake (TDFI)
- Population
- Humans using fluoride-containing dental care products; 28 included studies, mostly young children, only two studies in adults (aged 20-35); areas with tap-water fluoride 0.04-3.05 mg/L
- Intervention
- Fluoride-containing dental care products (mainly fluoride toothpaste; one study also included fluoride varnish)
- Comparison
- Dietary fluoride sources (drinking water, beverages, food)
- Outcome
- Contribution of dental care products to total daily fluoride intake (TDFI)
Fluoride-containing dental care products (mainly toothpaste) contributed on average 38% (SD 27%) of total daily fluoride intake, regardless of tap-water fluoride level or age (ungraded; descriptive synthesis, no meta-analysis).

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
