[Local effect of various fluoridation substances].

Area of Science:

• Dentistry
• Materials Science

Background:

• Topical fluoride application is a key strategy for preventing dental caries.
• Different fluoride preparations exhibit varying fluoride uptake characteristics in human enamel.

Purpose of the Study:

• To determine the rate of fluoride uptake by surface enamel from three distinct fluoride applications: sodium fluoride, amine fluoride, and fluorosilicate.
• To compare the fluoride concentrations achieved by these different topical agents.

Main Methods:

• Human enamel samples were treated with sodium fluoride, amine fluoride, and fluorosilicate preparations.
• The rate of fluoride uptake into the surface enamel was measured for each preparation.

Main Results:

• Amine fluoride treatment resulted in the highest fluoride concentrations in the enamel.
• The fluoride concentrations achieved with amine fluoride were also the most stable over time.
• Differences in fluoride uptake were observed between the tested fluoride preparations.

Conclusions:

• Amine fluoride demonstrates superior performance in achieving high and stable fluoride concentrations in tooth enamel.
• This suggests amine fluoride may be a more effective agent for topical caries prevention.
