How Much Fluoride?

• DMFT scale:

  Damaged Missing Filled Teeth

  • Poor areas = high
  • Affluent areas = low
• Data collected from public survey

  
• Graph shows, as fluoride concentration increases:

  • DMFT in children decreases.
  • amount of fluorosis increases.

  But when concentration are above 0.7mg/dm^3 that amount of fluorosis increases significantly

  Concentration higher than 1.2mg/dm^3 doesn’t further reduce DMFT.
• Graph shows:

  • concentration of 0.7 - 1.2mg/dm^3 of fluoride will have biggest impact on DMFT in children with the least negative impact.
