Systemic fluoride

Area of Science:

• Dental Public Health
• Cariology
• Preventive Dentistry

Background:

• Fluoride is a well-established agent for controlling dental caries development.
• Historical use includes natural water fluoride and community water fluoridation programs.
• Systemic fluoride delivery via supplements (salt, milk) has also been utilized.

Purpose of the Study:

• To review the evidence on fluoride's efficacy in caries prevention.
• To discuss the mechanisms of fluoride action, emphasizing topical effects.
• To evaluate the continued relevance of systemic fluoride delivery methods.

Main Methods:

• Review of existing scientific literature on fluoride and dental caries.
• Analysis of studies investigating systemic versus topical fluoride application.
• Examination of factors influencing fluoride effectiveness, including widespread use of multiple modalities.

Main Results:

• Fluoride's primary mechanism of action is post-eruptive and topical.
• Effectiveness of water fluoridation may be reduced due to other fluoride sources.
• Systemic methods, though acting topically, remain relevant for individual and public health.

Conclusions:

• Systemic fluoride delivery methods are still valuable, but require careful management.
• Excess fluoride ingestion must be avoided, especially with combined sources, to prevent dental fluorosis.
• Optimal fluoride dosage can be achieved by integrating both topical and systemic approaches.
