Summary

Higher fluoride levels in dental plaque significantly reduce cavities in children. Children with plaque fluoride between 21-30 ppm showed the lowest prevalence of dental caries.

Area of Science:

  • Dental Public Health
  • Fluoride Research
  • Pediatric Dentistry

Background:

  • Dental caries remains a significant public health issue in children.
  • Fluoride exposure through drinking water is known to impact caries development.
  • Variations in local water fluoride levels can lead to differential exposure.

Purpose of the Study:

  • To examine the relationship between dental plaque fluoride concentration and caries prevalence in 12-year-old children.
  • To compare caries prevalence in areas with minimal versus optimal/higher drinking water fluoride levels.
  • To determine the impact of plaque fluoride content on dental caries incidence.

Main Methods:

  • Standardized epidemiological methods were used to assess caries prevalence.
  • Dental plaque samples were collected from 12-year-old children in two distinct geographical areas.

  • Fluoride concentration in dental plaque was quantified using an Ion-selective electrode method.

    • Main Results:

    • Children from Vranjska Banja (optimal/higher water fluoride) had significantly higher plaque fluoride levels (36.5 ppm) compared to Valjevo (minimal water fluoride) (7.8 ppm).
    • A strong inverse correlation was observed between plaque fluoride content and caries prevalence; higher plaque fluoride was associated with lower caries rates.
    • The lowest caries prevalence was documented in children exhibiting 21-30 ppm fluoride in their dental plaque.

    Conclusions:

    • Plaque fluoride concentration is a critical factor in modulating dental caries risk in children.
    • Optimal or higher fluoride levels in drinking water contribute to increased plaque fluoride, thereby reducing caries prevalence.
    • Targeting plaque fluoride levels, potentially through water fluoridation or other interventions, can be an effective strategy for caries prevention in pediatric populations.
