dectaflur dectaflur 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. dectaflurclinical dataroutes ofadministrationtopical (gel, solution)atc codenonelegal statuslegal status in general: over-the-counter (otc) identifiers iupac name 9-octadeceylamine hydrofluoride cas number7333-84-8 ypubchem cid6433498chemspider4938643uniiq3b1y93c1schemblchembl2106567comptox dashboard (epa)dtxsid7073484 echa infocard100.297.781 chemical and physical dataformulac18h38fnmolar mass287.507 g·mol−13d model (jsmol)interactive image smiles .c(=c/cccccccc)\cccccccc inchi inchi=1s/c18h37n.fh/c1-2-3-4-5-6-7-8-9-10-11-12-13-14-15-16-17-18-19;/h9-10h,2-8,11-19h2,1h3;1h/b10-9+;key:qgscpwwhmscfov-rrabgkblsa-n chemistry and mechanism of action 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. side effects 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.
