Summary
This summary is machine-generated.

High fluoride in drinking water did not impact dental age in Egyptian children. Tooth emergence remained unaffected in children aged 8 to 14.5 years, despite elevated fluoride levels.

Area of Science:

  • Pediatric Dentistry
  • Environmental Health
  • Public Health

Background:

  • Fluoride is essential for dental health, but excessive levels can pose risks.
  • Understanding the long-term effects of naturally occurring high fluoride in drinking water is crucial for public health.
  • Matrouh Governorate, Egypt, has a community with naturally elevated fluoride levels in its water supply.

Purpose of the Study:

  • To assess the impact of chronic exposure to high fluoride concentrations in drinking water on the dental age of children.
  • To compare the dental age of children in a high-fluoride area with established dental standards from fluoride-deficient regions.

Main Methods:

  • Dental age assessment was conducted on 1286 Egyptian children (674 males, 612 females) aged 8 to 14.5 years.

  • Children were from Matrouh Governorate, a community with naturally occurring over-optimal fluoride levels in drinking water.
  • Dental ages were compared against Egyptian standards from a fluoride-deficient area with similar socioeconomic status.

    • Main Results:

    • The study found no significant long-term effect of communal water supply with fluoride ion concentration above the optimal level on dental age.
    • Tooth emergence patterns in the studied children were consistent with expected developmental timelines.
    • No adverse impact on dental development, as indicated by tooth emergence, was observed.

    Conclusions:

    • Naturally occurring over-optimal fluoride levels in drinking water do not negatively affect the dental age of growing children in Matrouh Governorate.
    • Tooth emergence is a reliable indicator of dental age and is not compromised by chronic exposure to high fluoride concentrations.
    • Public health recommendations regarding fluoride intake should consider regional water conditions and their impact on dental development.
