Indiana University-Purdue University Indianapolis (IUPUI) / The purposes of this study were twofold: (1) to determine whether
applying zirconium silicate prophylaxis paste (containing nine per cent
stannous fluoride) prior to topical application of 10 per cent aqueous
solution of stannous fluoride would promote a significantly greater enamel
fluoride uptake than when the solution was applied alone; and (2) to determine
whether rinsing the mouth with tap water immediately after these
procedures would significantly affect enamel fluoride uptake.
A modification of an in vivo, acid-etched enamel biopsy technique was
used to measure fluoride and calcium contents of the outermost layer of
enamel in first permanent molars and primary cuspids of 89 children. Four
sites were biopsied prior to treatment. Treatments involved prophylaxes
with a zirconium silicate paste either containing or not containing nine
per cent stannous fluoride, followed by either a four-minute topical application
of 10 per cent stannous fluoride in an aqueous solution or no such
topical application. Some participants were instructed not to rinse for
one-half hour; others were immediately offered unlimited quantities of
tap water. Four other sites were biopsied one week after treatment; four
more were biopsied two weeks after treatment.
Pre- versus post-treatment differences were measured via a fluoride-sensitive
electrode and atomic absorption spectrophotometry.
Results were inconclusive. Enamel fluoride uptakes for most treatment
groups appeared to be negative. Due to this seeming disagreement with the
findings of many other investigators, and due to the very small numbers within
treatment groups and biopsy sites, it was felt that uptake comparisons from
group to group would be misleading. Tentative explanations for the unexpected
results were offered.
