Slide 1 : ROLE OF FLUORIDE IN DENTISTRY Fluoride in form of stable compounds, are released into the environment naturally in both water and air. In humans, fluoride is mainly associated with calcified tissues (i.e., bones and teeth) because of its high affinity for calcium
Slide 2 : Fluoride has the ability to inhibit or even reverse the initiation and progression of dental caries The first use of adjusted fluoride in water for caries control started in 1945 and 1946 in the United States and Canada The success of water fluoridation in preventing and controlling dental caries led to the development of fluoride-containing products
Slide 3 : Dental caries also known as tooth decay is an infectious, multifactorial disease in which bacterial by product(acids) damages the tooth surface and sometimes it penetrates the tooth surface into the dentine and pulp and affects it aswell. Dental caries leads to loss of tooth structure, pain, and tooth loss and can progress to acute systemic infection.
Slide 4 : INCREASED RISK FOR DENTAL CARIES People with low socioeconomic status (SES) no access to dental services active dental caries root surfaces exposed by gingival recession poor oral hygiene malformed enamel or dentin reduced salivary flow because of medications, radiations or disease orthodontic appliances or dental prostheses.
Slide 5 : ACTIVITY OF CARIOGENIC BACTERIA Cariogenic bacteria causing dental caries reside in dental plaque and grow on tooth surfaces and produce polysaccharides that enhance sticking of the plaque to enamel. A carious lesion is formed when cariogenic bacteria in dental plaque metabolize a substrate from the diet and there is a demineralization of enamel surface by the by-product.
Slide 6 : Reduce demineralization2,3 Inhibit acid generation from plaque bacteria4 Promote remineralization1 HOW FLUORIDE WORKS
Slide 7 : Fluoride prevents loss of minerals from tooth enamel through formation of fluorohydroxyapatite and causes remineralization Fluoride inhibits cariogenic bacteria . At low pH, fluoride combines with hydrogen ions and diffuses into oral bacteria as hydrogen fluoride (HF).Inside the cell HF dissociates, acidifies the cell and inhibit glycolysis . Fluoride reduces the occurance of dental caries and prevents cavities Decay risk is reduced more when fluoride is combined with a healthy diet and good oral hygiene
Slide 8 : SOURCES OF FLUORIDE Topical agents Fluoridated water Ingested sources
Slide 9 : FLUORIDE THERAPY SYSTEMIC TOPICAL Tooth pastes Mouth rinses Varnishes Gels Dietry supplements Tablets Water fluoridation
Slide 10 : TOOTHPASTES: 1.1% sodium fluoride is safe and effective in prevention of caries .    GELS/FOAMS: Gels and foams are used for individuals who are 1 at high risk for caries 2 orthodontic patients The gel or foam is applied using a mouth tray
Slide 11 : VARNISH practical advantages of varnish over gels is 1. in ease of application 2. a non-offensive taste The varnish is applied with a brush and sets within seconds. MOUTH RINSES: Sodium fluoride is used in mouth rinses.Solutions of 0.05% sodium fluoride for daily rinsing are available for use.
Slide 12 : DIETARY SUPPLEMENTS In non fluoridated areas children are primarily given dietary fluoride supplements in the form of tablets   SYSTEMIC
Slide 13 : WATER FLUORIDATION Fluoridation is the controlled adjustment of a fluoride compound to a public water supply in order to bring the fluoride concentration up to a level which effectively prevent caries. The optimum water fluoride concentration range is 0.5ppm – 1.0ppm.
Slide 14 : FLUORIDE TOXICITY fluorides may cause allergies neurological damage enamel fluorosis ENAMEL FLUOROSIS also known as mottled enamel occurs when fluoride IS ingested and results in a range of visually detectable changes in enamel opacity (i.e., light refraction at or below the surface) because of hypomineralizatio,certain extremes of which are cosmetically objectionable
Slide 15 : CONCLUSION Its drawbacks are less than it benefits so it is a good addition to dentistry for the well being of mankind. Prevention of carries by fluoridation is less expensive than the treatment of carries if not done.
