The mechanism of action of topically applied sodium fluoride includes all of the following EXCEPT-
When sodium fluoride solution is applied on the tooth surface as a topical agent, it reacts with the hydroxy apatite crystals in enamel to form calcium fluoride which is the main end product of the reaction.
As a thick layer of calcium fluoride gets formed, it interferes with the further diffusion of fluoride from the topical fluoride solution to react with hydroxyapatite and blocks further entry of fluoride ions.
Calcium fluoride acts as a reservoir for fluoride release
The stoppage of release of fluoride is termed as chocking off effect.
