[The glass ionomer cements as bases or linings].

Abstract

The glass ionomer cements were developed in the early 1970s as filling restorative materials. Today, they have been modified for various clinical applications and the major of them is as base or lining, specially beneath composite resins. This paper is a literature review about the base/lining type of glass ionomers. The composition, the structure and the physicomechanical properties of this type are reported. Also, are presented the possibilities and results of their usage as base/lining in the restorations of amalgam and composite resins.
