In vitro Evaluation of the Remineralizing Potential and Color Change of Modified Fluoride Varnish with Polyvinylpyrrolidone-Coated Silver Nanoparticles on Incipient Enamel Lesions in Primary Teeth.

Researchers compared three treatments for early enamel decay in primary teeth: standard fluoride varnish, silver diamine fluoride, and fluoride varnish combined with silver nanoparticles. The silver nanoparticle-enhanced varnish showed strong remineralizing ability with minimal tooth discoloration, while silver diamine fluoride was most effective but caused visible staining.
