Study Notes

Systemic Use of Fluoride

  • Fluoride occurs naturally in the environment, released from rocks into soil, water, and air.
  • All water contains some fluoride, but usually not enough to prevent tooth decay.
  • Some groundwater and natural springs contain naturally high fluoride levels.
  • Fluoride is used in various forms for systemic delivery, including water, milk, and salt.

Community Water Fluoridation (CWF)

  • CWF involves adjusting the fluoride level in public water supplies to an optimal level.
  • It's a cost-effective method for preventing tooth decay.
  • CWF reduces tooth decay in children and adults by approximately 25%.
  • Exposure to water fluoridation is highly protective against tooth decay.
  • This process also reduces oral health inequalities within communities.

Milk Fluoridation

  • Adding fluoride to milk is a systemic method for delivering fluoride.
  • Fluoridated milk is effective in preventing dental caries, especially in children's primary teeth.
  • The level of fluoride added to milk ranges between 2.5 mg/L and 5 mg/L.
  • Children are usually advised to drink about 200 mL of fluoridated milk daily.
  • Milk fluoridation programs typically last for 200 days per year.
  • The consumption of fluoridated milk before children are 4 years old, and for approximately 200 days a year is recommended.

Salt Fluoridation

  • Fluoride can be added to salt to deliver fluoride systemically.
  • Fluoridated salt is an available and affordable option for communities.
  • This method is potentially effective in preventing dental caries, particularly in school children.
  • The fluoride content in fluoridated salt is usually between 200 ppm and 250 ppm fluoride.
  • The effectiveness of this method could be equal to that of water fluoridation, but currently, confidence in this method is graded as very low.

Fluoride Supplements

  • Fluoride supplements come in various forms, such as tablets, lozenges, and drops, offering supplemental fluoride intake.
  • The daily dosage for fluoride supplements is determined by a dentist or healthcare professional based on the local water fluoride level.
  • The dosage prescribed depends on the age of the individual.
  • Some evidence supports effectiveness, but the evidence is inconsistent, and confidence in the evidence is low.
  • Fluoride supplements should be used only as prescribed and are stored out of reach of children.

Malaysian Dental Council (MDC) Recommendation

  • The MDC advises against the use of any fluoride supplement, salt fluoridation or milk fluoridation, and promotes only water fluoridation.
  • Only one source of artificially adjusted systemic fluoride is recommended.
  • The current only recommended source of systemic fluoride is water fluoridation.

Conclusion

  • CWF is a commonly used and effective method for preventing dental caries.
  • Potential systemic benefits of fluoride via various methods are well-researched.
  • Continued research and public awareness are vital to ongoing implementation of effective programs.
