Fluoride and dental age.

Area of Science:

• Pediatric Dentistry
• Environmental Health
• Public Health

Background:

• Fluoride in drinking water is common, with varying concentrations globally.
• Optimal fluoride levels are crucial for dental health but excessive exposure can be detrimental.
• Understanding the long-term effects of naturally occurring fluoride on child development is essential.

Purpose of the Study:

• To investigate the impact of naturally occurring fluoride in drinking water on the dental age of children.
• To compare the physiological maturation, assessed by dental age, in children from high-fluoride and low-fluoride environments.

Main Methods:

• Comparative study involving 149 children from a high-fluoride district (up to 2.0 mg/l) and 181 control children from a low-fluoride district (≤0.1 mg/l).
• Dental age assessment was performed on children aged 9–12 years.
• Dental ages were compared against normative standards and between the two groups.

Main Results:

• No significant difference was observed in dental ages between children exposed to naturally occurring fluoride (up to 2.0 mg/l) and the control group.
• Dental ages in both groups were found to be within the normal range for their chronological age.
• Physiological maturation, as indicated by dental age, did not appear to be affected by the fluoride concentrations studied.

Conclusions:

• Naturally occurring fluoride in drinking water at concentrations below the highest recommended levels does not seem to adversely affect long-term physiological maturation in children.
• Dental age is a reliable indicator for assessing the impact of environmental factors like water fluoride on child development.
• These findings support the safety of drinking water with naturally occurring fluoride within the studied range for child development.
