Fluorides play an important role in mineralization of bones and teeth. they can be classified as topical fluorides and systemic fluorides. Topically applied fluoride agents are widely used in dentistry for prevention of dental caries.

1. TOPICAL FLOURIDESThe term “topically applied fluorides” is used to describe those delivery systems which provide fluoride for a local chemical reaction to
exposed surfaces of erupted dentition.
SODIUM FLOURIDE STANNOUS FLOURIDE ACIDULATED PHOSPHATE FLOURIDE
-First fluoride compound to
-be used for topical application.
-Applied using the Knutson technique
ADVANTAGES :
-Relatively stable
-Acceptable taste
-Non irritating
-No discoloration
DISADVANTAGES :
- Multiple visits
-applied using Muhler’s technique
ADVANTAGES :
-Fewer appointments
DISADVANTAGES :
-Not stable in aqueous
solution
-Astringent and
disagreeable in taste
-Causes reversible tissue irritation
-Light brown staining of teeth
-Applied using the Brudevold technique
ADVANTAGES :
-Only 2 appointments a year
-Low cost of application
-Stable preparation
DISADVANTAGES :
-Increased chair side time
-Acidic, sour and bitter
to taste
-Prolonged exposure can
cause surface roughening
INDICATIONS :
-Caries active individuals
- Shortly after tooth eruption
- Mentally and physically challenged
- Xerostomia
MECHANISM OF ACTION :
- Reduces enamel solubility
- Increases rate of post eruptive maturation
- Causes remineralization of incipient lesions
- Interferes with plaque micro organisms
- Causes modification in tooth morphology
These products are usually bought and dispensed by the individual patient. These
products include fluoride dentifrices, mouth rinses and gels and typically are low
fluoride concentration products ranging from 200 to 1000 ppm or 0.2 – 1.0 mg
fluoride / ml.
