Summary

Balancing fluoride benefits against dental fluorosis risks is crucial for caries prevention. Water fluoridation and fluoride toothpaste are most effective, while other methods should target high-risk groups.

Area of Science:

  • Dental Public Health
  • Caries Prevention
  • Fluoride Research

Background:

  • Fluoride use for caries prevention presents a complex balance between benefits and risks, particularly dental fluorosis.
  • Understanding dental fluorosis (definition, appearance, prevalence) is essential for informed decision-making.
  • Recent literature and guidelines inform current fluoride recommendations.

Purpose of the Study:

  • To review the current literature on dental fluorosis and fluoride use for caries prevention.
  • To evaluate the efficacy and risks associated with various fluoride modalities.
  • To provide evidence-based recommendations for optimal fluoride use.

Main Methods:

  • Comprehensive literature review of studies on dental fluorosis and fluoride efficacy.
  • Analysis of fluoride content in foods and beverages.
  • Examination of the Iowa Fluoride Study and CDC recommendations.
  • Assessment of esthetic perceptions related to dental fluorosis.

Main Results:

  • Water fluoridation and fluoride toothpaste are the most cost-effective methods for caries prevention.
  • Dental fluorosis risk necessitates careful consideration of fluoride dosage and application.
  • Targeted application of other fluoride modalities is recommended for high-risk individuals.

Conclusions:

  • Fluoride remains a cornerstone of dental caries prevention, but its use requires careful risk-benefit assessment.
  • Public health strategies should prioritize water fluoridation and fluoride toothpaste.
  • Personalized approaches are needed for individuals at higher risk of dental caries or fluorosis.
