4. Mechanism of action:
• Fluoride is electronegative element and therefore highly reactive in nature.
• Maximum fluoride concentration presents near the incisal edges.
• It strengthen the tooth in pre eruptive and post eruptive stages of tooth by
formation of apatite structure.
5. • Remineralization process:
A balance is maintained in saliva and enamel of tooth because exchange of
minerals occur, but in presence of plaque, bacteria produces organic acid that
demineralized the enamel.
Then the fluoride form new hard crystals they are white spot.
Fluorhydroxyapatite also speed up the process of remineralization
6. • Inhibit demineralization:
Fluoride crystals are hard so it required strong acid to be dissolved.
• Antibacterial:
Formation of hydroxyfluoride.
7. Available resources:
• Fluoride water
• Minerals
• Vitamins
• Toothpastes
• Mouthwashes
• Fluoride gel
• Fluoride varnish
• Fluoride solution
8. Recommended Dosages:
• The daily intake level of fluoride at highest level with no harmful effects:
• 0.1-0.7mg for infants 0-6 months ago
• 0.5-0.9mg for 7-12 months of age
• 0.7-1.3mg for children 1-3years of age
• 1-2.2mg for children 4-8 years of age
• 2mg r above for children 9-13 year of age
• 10mg for adults
