Systemic fluoridation

Topical fluoride therapy

- Dentifrices - Mouth rinses - Fluoridated gel

1 -Self – applied fluoride

Fluoride

Na2PO3F (MFP).

Decrease solubility, antibacterial. PO3F 2 + H2O H2PO4 + F

Stannous Fluoride, NaF, Amine fluoride 525 -1450 ppm (1000 ppm F).

Fluoridated Mouth Rinse

NaF (900 ppm F, 0.2% weekly) (225 ppm, 0.05% daily). APF, SnF2, Amine fluoride,

Ammonium fluoride.

Professionally Applied Fluoride

Sodium fluoride NaF Bibby 1942, Knutson tech

Stannous Fluoride SnF2

Muhler et al 1950, 8%, 10 %, pH=2.1.

Ca10(PO4)6(OH)2 + 19 SnF2

10 CaF2 + 6Sn3F3PO4 + SnO.H2O tinfluorophospate hydrated tinoxide

Stannous Fluoride

Not stable, metallic taste, staining.

Prevention, Remineralization, desensitizing, antibacterial.

Acidulated phosphate fluoride

Brudevold et al 1963Increase F conc.Ca10(PO4)6(OH)2 + 20 F 10CaF2+6(PO4) -3+ 2(OH).

2.26% F ions.

Applications Frequency

NaF 3-6 months.APF, SnF2 6-12 months.3,6,12 months.

Fluoridated Gel

APF 0.5% FNaF 1% SnF2 0.4%

Fluoride in periodontal therapy

Plaque related disease.Stannous Fluoride: - Reduce plaque (gingivitis). - Reduce enamel solubility. - Antibacterial (specific). - Reduce dental hyper sensitivity.

Types of PatientsType I : (periodontally healthy patient) Treatments: 1- Decrease of dental sensitivity. 2- Reduce plaque volume and age. 3- Reduce deleterious effects of pathogen. 4- Increase retention of fluoride in dental plaque.

Long term high conc. Of fluoride (dentifrices, mouth rinses, gels)

Type II patients

Periodontal treatments.Control of plaque pathogens. Reduce plaque volume. Reduce post operative sensitivity.Prevents of root caries.

Fluoridated Agents

NaF, APF, SnF2 SnF2 0.4 %, 1.64%.Irrigation of F solution in to the

pocket.Use as a gel (brush on gel).A combination of CHX and F.
