Prospektiv epidemiologi: Eksponering for fluorid kan skade hjernens udvikling
Mens fluorid har veldokumenteret gavnlig virkning på tandemaljen, kan forhøjet systemisk eksponering føre til skadelige effekter.

Prospektiv epidemiologi: Eksponering for fluorid kan skade hjernens udvikling
Man har længe vidst, at fluorid kunne virke giftigt, men indtil for knap 100 år siden byggede denne viden på kasuistikker, de fleste om ulykkestilfælde.
