^^ Can you explain the relevance to the subject, i.e. "the truth about fluoride"?
Because as far as I can see, this cool discovery has absolutely nothing to do with toothpaste.
The word "fluorinated" in the above article, depending how it is used, is a verb or an adjective pertaining to something that is treated with fluorine. A fluoride molecule is a molecule that has at least one fluorine atom in it. To get that molecule, some element or other molecule must be fluorinated (treated with fluorine) in some way.
One can easily guess from the "f l u o r i" that starts the words fluoride, fluorinated, and fluorine, that they are all associated, chemically. Searches on the words will show the ways they are associated.
Yes, fluorinated means it has a fluorine atom in it somewhere. This is not necessarily bad or good. For example, sodium chloride has two elements in it which are very dangerous on their own, but in a salt molecule they are relatively harmless.
The fact that implants may be fluorinated doesn't mean that they are dangerous, in the same way that fluorine gas is. Likewise, salt is not dangerous, in the way that chlorine gas is.
