Remineralizing Agents

Dental caries, affecting teeth through demineralization and cavitation, remains a significant global health concern. The balance between demineralization and remineralization is crucial in maintaining oral health. Remineralizing agents, such as fluorides, tri-calcium phosphate, amorphous calcium phosphate, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), and others, play a vital role in reversing early carious lesions. These agents work by supplying necessary ions like calcium and phosphate to the demineralized enamel, promoting the deposition of minerals and enhancing the tooth's resistance to acid attacks. Fluorides, introduced through various delivery methods, have been shown to significantly reduce caries prevalence by promoting the formation of fluorapatite, which is more resistant to acid dissolution than hydroxyapatite. The effectiveness of these agents depends on several factors, including their ability to penetrate the enamel, the presence of calcium and phosphate ions, and the overall oral environment. The document further explores various remineralizing agents, their mechanisms, and their clinical implications in preventing and treating dental caries.
