Abstract
An improved method for securing a thin continuous layer of metallic silver upon a tooth structure, especially the dentin surface of that structure, to seal the surface and, where desired, to provide a highly receptive surface for an amalgam restoration. The method involves first coating the dentin surface with an aqueous solution of a silver salt to form a silver-protein complex, then photoreducing the silver of that complex to produce a black base layer of complexed metallic silver, and thereafter electrolessly plating a continuous silver sealing layer onto the base layer.
