Fluroide concentration in enamel treated with 50% phosphoric acid and NaF with subsequent decalcification in "acid-gel"
J. Bohrer and I. Gedalia
Fluoride concentration of enamel surfaces treated with 50% H3PO4, together
with high NaF contents or etched with 50% H3PO4 followed by application
with a water solution of high NaF content, was examined. In addition, the
degree of decalcification and the fluoride content of subsequently
incubated enamel samples in acid-gel at 37 degrees C were determined.
Generally, incubation highly increased the fluoride contents of the etched
and fluoridated (experimental), control (etched only), and untreated
(vaseline) enamel samples. An increasing demineralization effect was
observed in the samples of the following order: experimental, control, and
baseline. It appears does not predispose to an increased caries challenge
in vitro.
