title: The effect of saliva on the formation of KOH-soluble fluoride after topical application of amine fluoride solutions of varying fluoride concentration and pH.
abstract: The effect of saliva on the amount of KOH-soluble fluoride formed on a sound enamel surface after application of amine fluoride solution of varying fluoride concentrations (1, 0.5 and 0.25% F) and pH (5.3, 4.5 and 4.0) was examined in an in vitro study. The saliva pretreatment increased the amount of KOH-soluble fluoride at the highest pH value. For any given fluoride concentration, the presence of saliva did not influence the amount of KOH-soluble fluoride. These data suggest that saliva could enhance the amount of KOH-soluble fluoride if the topical fluoride preparations are not highly acid.
