The role of fluoride ions on the corrosion behavior of some commercial dental
amalgam in artificial saliva solution at pH level 7.1 was studied by using
impedance and potentiodynamic polarization techniques. It was found that, the
presence of F- ions in an artificial saliva solution at pH 7.1 increases the
corrodability of different types of dental amalgam. Sever pitting corrosion
occurred at level of 100 mM F- ions. The formulation of amalgam alloys greatly
affect the resistance to pitting corrosion; the resistance of the amalgam to
pitting follows the order: Dispersalloy >> Phasealloy > Oralloy > Tytin >
Valiant-pH.D. It is recommended to avoid oral treatment involving high F- ions
concentration in the presence of amalgam restorations.

Oh thanks so much for this! Now tell me again, why do I want to know
this?

And ...... as Mark Tarka says, "What's this got to do with Florida?"

He/she's talking about flouride mined in Florida. Mel

Yup,

They dug a huge pit and then they had to fill it up with Disney world!
