    Study Notes

    Dental Health

    • Dr. Frederick McKay discovered brown stains and fewer cavities in Colorado Springs in the early 20th century. H.V. Churchill identified fluorine as the cause in 1931. Dr. H. Trendley Dean established optimal prevention levels at 1 ppm in the 1930s. First community water fluoridation began in 1945.

    Fluoride and Tooth Development

    • Pre-Eruptive Stage: Primary teeth formation begins in utero. First permanent molars begin mineralization at birth. Fluoride reaches developing teeth through circulation. Hydroxyapatite becomes fluorapatite. Contributes to shallow occlusal grooves.
    • Post-Eruptive Stage: Rapid uptake on enamel surface in first years after eruption. Ongoing uptake continues throughout life due to surface exposure. Drinking water provides a continual topical source.

    Mechanisms of Action

    • Protective Effects: Inhibits demineralization. Enhances remineralization. Inhibits bacterial activity by blocking enolase enzyme. Natural constituent of enamel, dentin, and cementum.
    • Remineralization Process: Saliva buffers and neutralizes acid. Calcium and phosphorous return to enamel. Fluoride enhances the process. Creates a more resistant fluorapatite structure.

    Water Fluoridation

    • Reduces caries by 27% in adults (excluding other fluoride sources). Reduces caries up to 40% in primary teeth when used from birth. Current recommended level is 0.7 ppm (updated 2015), previously varied from 0.7-1.2 ppm based on climate (1962).

    Fluoride Sources

    • Found naturally in meat, eggs, vegetables, cereals, fruits. Higher levels in tea and fish. Fluoridated salt available in Europe.

    Additional Information

    • Well water varies by location, and is found in manufactured sources like bottled water, infant formula, and dietary supplements. Professional applications include 2% Neutral Sodium Fluoride (9,050 ppm), APF (12,300 ppm), 5% Fluoride Varnish (22,600 ppm), and 38% Silver Diamine Fluoride.

    • Self-applied fluorides such as mouth rinses are available in prescription and over-the-counter strengths.

    • Types of stains are categorized as extrinsic (located on the external surface of the tooth) and intrinsic (located within the tooth structure) and can have causes such as tobacco, tea, coffee, cola, chlorhexidine, betel nut and red wine,.
