Dectaflur (INN) is a fluoride-containing substance used for the prevention and treatment of dental caries, sensitive teeth, and the refluoridation of damaged tooth enamel, typically in combination with olaflur.[1]

Chemistry and mechanism of action[edit]

Dectaflur consists of oleyl amine (the amine corresponding to oleyl alcohol) and hydrofluoric acid. Oleyl amine with its long lipophilic hydrocarbon chain has surfactant properties. It forms a film layer on the surface of teeth, which facilitates incorporation of fluoride into the top layers of the enamel, reaching a depth of only a few nanometers. The precise mechanism of action is unknown.[2]

Side effects[edit]

Like other fluorides, dectaflur is toxic when overdosed over an extended period of time. Especially in children, before the development of the permanent teeth, overdosage can lead to dental fluorosis.[3]
