Sodium fluoride (NaF) was the first fluoride compound to be used for topical application. The first clinical study was started by Bibby in 1941 using a 0.1% aqueous NaF solution. In 1942 Knutson applied a 2% aqueous NaF solution for 3 minutes, he suggested that the series of applications should be carried out at the age 3,7,11 and 13 years to coincide with the eruption of teeth and a caries reduction of 30%.
