Laboratory enamel fluoride uptake from fluoride products.

Area of Science:

• Dental materials science
• Cariology
• Biomineralization

Background:

• Fluoride is crucial for preventing dental caries.
• Different fluoride formulations vary in their enamel uptake and retention.
• Understanding long-term fluoride concentration is key to optimizing caries prevention strategies.

Purpose of the Study:

• To compare enamel fluoride concentration after using different fluoride products.
• To assess fluoride levels 48 hours after discontinuing product use.
• To determine the long-term effectiveness of amine fluoride versus sodium fluoride.

Main Methods:

• 16 enamel slabs were treated for 15 days with amine fluoride or sodium fluoride toothpaste and mouthrinse.
• Fluoride concentration was measured using chemical biopsy.
• Statistical analysis included two-way ANOVA and Tukey HSD tests.

Main Results:

• Group A (amine fluoride toothpaste and mouthrinse) exhibited the highest fluoride uptake (0.19 microg mm(-2)).
• Higher fluoride concentrations persisted in Group A samples 48 hours after product cessation.
• Amine fluoride products demonstrated the most effective long-term enamel fluoride retention.

Conclusions:

• Amine fluoride formulations provide superior and sustained fluoride uptake in enamel.
• These findings support the use of amine fluoride products for enhanced caries prevention.
• Long-term fluoride retention is a critical factor in the efficacy of anticaries agents.
