Recent Advances in Remineralization Therapies for Caries Lesions.

Abstract

Remineralization of caries lesions is naturally achieved by salivary ions, and it can be enhanced by external factors or elements such as fluoride. Numerous studies have demonstrated the remineralizing efficacy of fluoride therapies as well as the limitations with some groups of the population. Consequently, developing new remineralization therapies to close this gap in efficacy has been a priority for the last 2 decades. In this review, we summarize and briefly discuss some of the latest advances in remineralization therapies. Most new therapies try to enhance the effect of fluoride by adding other potentially active ingredients to the formulation, such as calcium, phosphate, stannous, xylitol, and arginine. Other remineralization strategies have focused on creating remineralizing scaffolds within the lesions (e.g., self-assembling peptides). While several of the new remineralization strategies have progressed significantly in recent years, for most of them, the evidence is still insufficient to assess their true clinical potential.
