[Problems of fluoride dosing to infants for dental fluorosis prevention]
Insights
High fluoride in drinking water increases infant exposure, risking dental fluorosis. Monitoring water fluoride is crucial for infant health and preventing this condition.
Area of Science:
- Environmental Health
- Pediatric Nutrition
- Dental Public Health
Context:
- Fluoride intake in infants is primarily determined by drinking water and food preparation.
- Breast milk provides minimal fluoride, while artificial feeding and complementary foods can significantly increase exposure.
- Elevated fluoride levels in drinking water pose a risk to infant health.
Purpose:
- To quantify fluoride content in various infant nutrition sources.
- To investigate fluoride excretion in infants based on feeding type.
- To assess the risk of dental fluorosis due to varying fluoride intake.
Summary:
- Fluoride levels in drinking water, breast milk, cow milk, and infant foods were analyzed.
- Infant urine was tested for fluoride excretion during the first four months of life.
- High fluoride in water significantly increased fluoride in prepared foods, exceeding breast milk levels and risking dental fluorosis.
Impact:
- Highlights the critical role of drinking water fluoride content in infant fluoride exposure.
- Emphasizes the necessity of assessing water fluoride levels to prevent dental fluorosis in infants.
- Provides data essential for public health strategies aimed at managing infant fluoride intake.
Abstract:
Fluoride content in drinking water, breast milk, cow milk, additional food for newborns prepared with water containing different amount of fluoride was determined. Fluoride excretion in urine since the first days of birth and up to 4 months of postnatal development was investigated in breast and artificially fed infants. When a neonate was fed with breast milk, fluoride was received in the amount no more than 20 mkg/day. The additional food contained fluoride which water mainly had. Water with high level of fluorine increased its content in the additional food up to the values not comparable to those in breast milk that presented danger of dental fluorosis development. Data on fluorine content in drinking water were absolutely necessary to calculate daily fluorides consumption by infants and to prevent dental fluorosis.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
