Electron spectroscopic depth profiles of the chemical composition of bovine incisors after fluoride treatment show that interactions are restricted principally to a hyperfine outermost layer of only 0.05 µm. In this zone, high fluoride concentrations of up to 20% are correlated with drastic surface enamel degradations. A mixed layer of calcium phosphates and calcium fluorides is formed.
