Solubility of Enamel Protected by Sodium Fluoride and other Compounds

Cariostatic Mechanisms of Fluorides: Clinical Observations

“…After it was shown that the stannous ion had a remarkable solubility reducing effect on enamel [Muhler and Van Huysen, 1947;Manly and Bibby, 1949;Ericsson, 1950], SnF, or SnCIF was applied as paintings or in dentifrices especially by Muhler and his collaborators. The results reported up to 1957 with 8°/o SnF2 were generally very fa vorable, but more recent reports have pro duced more modest caries reductions, e.g., Muhler [1961].…”

Chemistry of Topical Fluorides

“…The observation that enamel powders treated with stannous fluoride solutions greatly reduced the rate of acid dissolution [Muhler and Van Huysen, 1947] is the ba sis for their use as topical agents. The reac tions of stannous fluoride with enamel in volve both the stannous ion and the fluo ride ion in contrast to APF solutions where the primary reactions involve fluoride ion and enamel and no specific role is attribut ed to the sodium ion.…”

A Study of Tin in Enamel

“…No tin could be detected in the bulk of the enamel of these teeth. 4. The tin content in the enamel of teeth with amalgam restorations was greater than that in the enamel of intact teeth.…”
