Study Notes
Dental Fluorosis
- Inappropriate fluoride supplements are a risk factor for dental fluorosis
- Early tooth brushing in children can increase the risk of dental fluorosis
- Frequent brushing and swallowing toothpaste can also contribute to dental fluorosis
- Living in areas with high water fluoride concentration is a risk factor for dental fluorosis
- Providing water with optimum fluoride concentration can prevent dental caries and fluorosis
Water Defluoridation
- Water defluoridation involves adjusting the fluoride level in drinking water to an optimal level that prevents dental caries and fluorosis
- Adsorption technique uses active agents like active alumina and activated carbons to remove fluoride from water
- Ion-exchange technique uses anion and cation exchange resins to remove fluoride from water
- Precipitation technique uses chemicals like calcium salts, strontium salts, or magnesium salts to remove fluoride from water
- Other techniques for water defluoridation include electro-dialysis and reverse osmosis
Learn about the risk factors for dental fluorosis, including inappropriate fluoride supplements and frequency of brushing, and how to prevent dental caries and fluorosis by providing water with optimum fluoride concentration.
