Fluoride inhibits root caries by preventing mineral loss and enhancing remineralization, similar to its effects on enamel caries. This review explores the mechanisms of dental caries and fluoride

Area of Science:

Dental Science
Biochemistry
Microbiology

Background:

Dental caries, including root caries, involves acid demineralization of tooth structure.
Oral bacteria metabolize carbohydrates, producing acids that initiate caries.
Root caries demineralization affects the collagenous organic matrix, which is further degraded by bacterial enzymes.

Purpose of the Study:

To review the probable mechanism of dental caries.
To elucidate the role of fluoride in inhibiting or reversing dental caries.

Main Methods:

Literature review of dental caries mechanisms.
Analysis of fluoride's role in mineral dissolution and remineralization.

Main Results:

Related Experiment Videos

Root caries initiation is comparable to enamel caries, involving acid dissolution of minerals.

Bacterial fermentation of carbohydrates by mutans streptococci and lactobacilli initiates root caries.

Fluoride inhibits mineral loss and promotes remineralization in root caries, mirroring its action on enamel.

Conclusions:

Fluoride plays a crucial role in managing and potentially reversing dental caries.
Understanding caries mechanisms informs effective fluoride-based prevention and treatment strategies.
