Sodium Fluoride Reagent Concentration and Powdered Enamel Solubility

Abstract
Exptl. evidence secured upon powdered dental enamel indicates that a 2% soln. of NaF is the most effective concn. to use in reducing enamel solubility. The best pH at this concn. is 4.5. Additional evidence is secured to show that if the NaF soln. is buffered, it is more effective at any concn.
