Abstract
Wet glass ionomer cement is applied to a tooth lesion. Before the cement hardens, wet amalgam is applied on top of the glass ionomer cement. The glass ionomer bonds to the tooth, and the interface of the wet cement and wet amalgam allows strong ionic bonds to form between the glass ionomer cement and the amalgam, to provide an exceptionally strong bond between the amalgam and the tooth.
