WHAT IS FLUORIDE?
• Fluorine is the ionic form of the element.
• Fluorine is a mineral found throughout the earth’s crust and widely
distributed in nature.
• Found in soils rich in fluorspar, cryolite and other minerals.
• Fluoride is often called as nature’s cavity fighters.
WHY FLUORIDE IS IMPORTANT IN
DENTAL HEALTH?
• Fluoride plays an important role in the mineralization of our teeth, keeping
them hard and strong
• About 99% of the body’s Fluoride is stored in bones and teeth.
• Fluoride is also important for preventing dental caries, also known as Cavities
OTHER CHIEF SOURCES OF FLUORIDE.
• Water
• Topical agents (toothpaste)
• According to WHO: Fluoridated Salts/Milk
CAVITIES
• Cavities, also known as caries are holes (or structural damage) in the teeth.
• It is an infectious disease caused by the complex interaction of caries-causing
bacteria with sugars on the tooth surface over time.
• Theses Bacterias metabolize sugars for energy and produce organic acids as
byproducts.
• The acids lower the Ph in the Plaque biofilm.
WHAT HARM DOES CAVITIES DO?
• Your teeth are under constant attacks by acids and bacteria.
• These substances will break down your teeth over time by causing tooth
decay.
• This tooth decay is in the form of cavities or holes which is a microscopic
damage to your tooth.
ROLE OF FLUORIDE
• Fluoride helps prevent cavities.
• It strengthens the Enamel which is the outer layer of our teeth.
• Alters the action of the Bacteria.
• Reduces the Enamel solublitity.
• Example: Sodium Fluoride(NaF), Stannous Fluoride(SnF2).
ROLE OF FLUORIDE
• Sodium Fluoride(NaF):
Synonymn-Florocid
Uses- 1)NaF makes teeth more resistant to decay and bacteria that causes
cavities.
2) It is used to prevent cavities.
ROLE OF FLUORIDE
• Stannous Fluoride(SnF2)
Synonym- Fluoristan
Uses-1)It is used in toothpaste for prevention of gingivitis dental infection,
cavities, and to release hypersensitivitiy
2)It manages and prevent dental caries and gingivitis by promoting enamel
mineralization.
WATER FLUORIDATION
• Technique in which there is addition of small amounts of Fluoride to public
water supply.
• Community water fluoridation is safe and effective in preventing dental
caries in both children and adults.
• Water fluoridation benefits all residents served by community water supplies
regardless served by community water supplies regardless of their social or
economic status.
SUMMARY
• Dental caries is a progressive disease characterized by demineralization and
destruction of enamel and dentine.
• Fluoride can reduce caries by preventing demineralization and promoting
remineralization of tooth surfaces and can also inhibit production of plaque
acid.
