Fluoride in Caries control

By Dr.Swathi Pai on Wednesday, 16 April, 2008 with 0 comments

-Reduction in caries 50%-60%

-enhancement of enamel remineralization

-water intake best vehicle

-dentifrices 1000 ppm (1450-2500 ppm) contain NaF or Na monofluorophosphate

-high dose topical Fluoride

2 % stannous Fluoride in water (mix daily, readily converts to stannous hydroxide)

APF 1.23 % Fluoride and .98% phosphoric acid (NaF, hydrofluoric acid, phosphoric acid) pH 3-3.5

-low dose rinses

.2% NaF once/week

.05% NaF daily

-Fluoride release curve and therapeutic benefit of Fluoride releasing restorative materials:

release curve: Initial high burst for a short period (1 week) followed by a rapid slow down

with a stable long-term low-dose release

therapeutic benefit: Low-dose fluoride release provides enamel/dentin protection via

remineralization mechanisms

Caries risk (Adults)

Office therapy

Home therapy


  • topical APF annually

  • Fluoride dentifrice (2-3x/day)


  • Topical APF or Fluoride varnish 2x/yr

  • diet modification

  • Fluoride dentifrice 2-3x/day

  • Fluoride rinse 1 min/1x/day


  • Topical APF or Fluoride varnish 2-4x/yr

  • Diet modification

  • Supress S mutans w/ 0.12% Chlorhexidine gluconate

  • Fluoride dentifrice 2-3x/day

  • Fluoride gel APF or NaF (5 min, 1x/day)

  • Salivary substitute if xerostomic

Fluoride releasing sealants have the potential to act as a slow release depot for Fluoride in the mouth to aid in the remineralization/demineralization reaction occurring daily
