Although glass-ionomer cements are generally agreed to show very good adhesion to a variety of substrates encountered in clinical dentistry, laboratory testing of this property has not proved to be straightforward. In the current paper we review the published literature describing the testing of gla

β¦ Synopsis
The literature on the clinical use of glass-ionomer cements is reviewed, and this shows that these materials are successful partly because of the good adhesion they exhibit towards a variety of substrates encountered in dentistry. The reasons for this good adhesion are identified as the good initial wetting of the surfaces met in clinical dentistry, the development of strong chemical bonding w~th the surface over time and the good mechamcal properties of the cements themselves, which make them resistant to cohesive failure. In this review these features are described in detail and related to established mechanisms of adhesion from the wider field of adhesives technology.

As part of a detailed investigation of the setting mechanisms of dental polyelectrolyte cements, the M3+, Ca2+, and Na+ concentrations in the matrix phase of glass ionomer cements were measured as a function of the cements age by use of a selective degradation technique. In the early stages of cemen
