Abstract

The effect of solutions of sodium fluoride in hydrofluoric acid on the fluoride-dental minerals reaction system was investigated. The fluoride concentration in each fluoride solution was kept at 1.23% as the fluoride concentration in the acidulated phosphate fluoride solution at pH 3. The acidic sodium fluoride-hydrofluoric acid solutions with different contents of sodium fluoride and hydrofluoric acid were prepared. These solutions were added to synthetic powder hydroxyapatite and calcium hydrogen phosphate crystal, respectively, and then precipitated for 10 min at room temperature. Acidulated phosphate fluoride solution (pH 3.0) was used as a control fluoride solution. The results of the analysis showed that the CaF2 content in the samples treated with acidic NaF-HF solution with relatively low hydrofluoric acid content was almost like that of the samples treated with acidulated phosphate fluoride. However, the CaF2 content in the samples treated with acidic NaF-HF solution with high hydrofluoric acid content was higher than that of the samples treated with acidulated phosphate fluoride. It was found that the chemical reactivity of hydroxyapatite with fluoride solution was related to the content of hydrofluoric acid and the ionic atmosphere, that is, the higher the content of hydrofluoric acid and lower the ionic concentration, the higher the reactivity.

Keywords: Acidic sodium fluoride-hydrofluoric acid solution (ANHS), CaF2, hydroxyapatite, fluorapatite, calcium hydrogen phosphate (burshite), chemical reactivity
