Fluoride-containing dental care products (mainly fluoride toothpaste) vs Dietary fluoride sources (drinking water, beverages, food): Contribution of dental care products to total daily fluoride intake (TDFI), by tap-water fluoride level

Population
Adults using fluoride-containing dental care products (two included studies [28,47]; aged 20-35)
Intervention
Fluoride-containing dental care products (mainly fluoride toothpaste)
Comparison
Dietary fluoride sources (drinking water, beverages, food)
Outcome
Contribution of dental care products to total daily fluoride intake (TDFI), by tap-water fluoride level

In adults in poor-fluoridated tap water areas, dental care products contributed on average 12% of total fluoride exposure (ungraded; 1-2 studies).

The same intervention and outcome, asked in another population or against another comparator.

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.
