Summary
This review examines fluoride intake and metabolism, linking excessive fluoride to endemic dental fluorosis. Understanding these factors is crucial for managing dental health and caries prevention.
Area of Science:
- Oral Health
- Environmental Health
- Biochemistry
Background:
- Endemic dental fluorosis results from excessive fluoride intake during tooth development.
- Fluoride is ubiquitous in water, soil, food, and industrial products, leading to varied human exposure levels.
- Waterborne fluoride is a primary source of daily intake, influenced by climate and age.
Purpose of the Study:
- To review current knowledge on fluoride ingestion and metabolism in relation to endemic dental fluorosis.
- To discuss the impact of changing dietary patterns and food processing on fluorosis prevalence.
- To highlight the ongoing importance of fluoride research for dental caries prevention.
Main Methods:
- Literature review of existing research on fluoride ingestion and metabolism.
- Analysis of factors influencing fluoride intake, including water, diet, and environmental exposure.
- Examination of clinical manifestations and severity of dental fluorosis.
Main Results:
- Dental fluorosis presents as enamel opacities, staining, pitting, and hypoplasia, varying in severity.
- Changes in food and beverage consumption patterns may have altered fluorosis prevalence over the past 30 years.
- Fluoride remains a key agent for enhancing tooth resistance to caries.
Conclusions:
- Continued research into fluoride ingestion and metabolism is essential.
- Understanding fluoride's role is critical for both preventing dental fluorosis and promoting caries resistance.
- Public health strategies may need to adapt to changing exposure patterns.
