ABSTRACT:
Metal bases, metal salts and/or metal oxides are added to an amalgam restoration formula for use in conjunction with a glass ionomer cement to restore a tooth lesion. The additive is comprised of an amount of metal bases, metal salts and/or metal oxides, such as the powder of a polycarboxylate dental cement, sufficient to improve the bond strength between wet glass ionomer cement applied to the tooth lesion and the wet improved amalgam applied to the wet cement. As a result, the retentive quality of such a restoration is improved and therefore may permit a lesion to be filled with amalgam rather than requiring extraction or the application of a prosthesis.
