What is the recommended concentration of fluoride for professional application?

0.5% Sodium Fluoride
1.23% Acidulated Phosphate Fluoride
2.0% Sodium Fluoride
0.3% Topical Fluoride

The correct answer is: 1.23% Acidulated Phosphate Fluoride

The recommended concentration of fluoride for professional application is 1.23% Acidulated Phosphate Fluoride. This concentration is considered effective for promoting remineralization of enamel and preventing dental caries. Acidulated phosphate fluoride has a lower pH, which enhances its ability to penetrate enamel and is beneficial for patients, especially those at a higher risk of caries. This specific formulation is commonly used in professional settings due to its efficacy in enhancing fluoride uptake into dental tissues. While other concentrations and formulations, such as 0.5% Sodium Fluoride and 2.0% Sodium Fluoride, are also used in different contexts, they do not provide the same level of efficacy for caries prevention as the 1.23% Acidulated Phosphate Fluoride. In addition, the 0.3% Topical Fluoride is typically used in over-the-counter products and is less concentrated, making it less effective in a professional application setting where higher fluoride concentrations are desired for optimal results.
