In vitro acid decalcification of human surface enamel pretreated with toothpaste slurries.

An in vitro caries-like challenge of human tooth enamel treated with inorganic fluoride (NaF) and organic fluoride (aliphatic and aromatic amine fluorides) toothpaste slurries has been investigated. The results revealed that the organic fluoride-containing toothpastes affected positively the resistance of tooth enamel to demineralization.
