What aspect of fluoride therapy is enhanced by the presence of casein phosphopeptide in solutions?

The presence of casein phosphopeptide (CPP) in fluoride therapy solutions enhances the remineralization process by keeping fluoride in a stable and bioavailable form. Casein phosphopeptide has the ability to stabilize calcium and phosphate ions, which are essential components for the remineralization of enamel. When fluoride is present in these solutions, the CPP forms a protective complex that allows fluoride to remain in solution, thereby providing a continued source of fluoride ions to the tooth surface over time.

This action favors the remineralization of demineralized enamel and enhances the protective effects of fluoride against dental caries. The enhanced stabilizing effect of CPP ensures that the fluoride can interact effectively with the enamel, promoting its incorporation into the dental structure and thus aiding in the repair of early carious lesions.

The other options reflect misunderstandings about either fluoride function or the role of CPP. For example, reducing fluoride efficacy contradicts the fundamental role of fluoride in enhancing tooth mineralization. Similarly, preventing fluoride from settling suggests a misunderstanding of the process, as retaining fluoride in a bioavailable form through the solution is more about maintaining active interaction than simply preventing physical settling. Lastly, the notion of degrading fluoride refers to its metabolic byproducts and not its therapeutic function, which emphasizes
