The behaviour of two commercial light-cured glass-polyalkenoate (“Glass-ionomer”) cements has been studied in terms of changes in strength following storage under various conditions. Unlike conventional glass-polyalkenoates, these materials cure partly by a photochemical polymerization process, in addition to the normal acid-base setting reaction. Results presented in the current paper show that these hybrid materials are able to take up a considerable amount of water when stored in either… 
Resin-modified glass-ionomer cements
The physical chemistry of light-curable glass-ionomers
This paper reviews aspects of the physical chemistry of light-curable glass-ionomer cements. These materials have a tendency to undergo phase separation in solution and, when set, to take up water
Glass ionomer dental cements: update
Modern conventional glass ionomers have improved particle size and particle size distribution, which leads to improvements in mechanical properties, which makes them suitable for more demanding applications, including in the modern clinical techniques of atraumatic restorative treatment and minimal intervention dentistry.
Effect of water on the physical properties of resin-modified glass ionomer cements.
Comparative study of the physical properties of a polyacid-modified composite resin and a resin-modified glass ionomer cement.
The Effects of Maturity and Dehydration Shrinkage on Resin-modified Glass-ionomer Restorations
The results of this study of the maturing polymerized resin-modified cements have potential clinical implications in the handling of these materials; the addition of resin has not significantly reduced the glass ionomer's susceptibility to dehydration problems.

A study of the relationship between setting chemistry and properties of modified glass-poly(alkenoate) cements
A study aimed at increasing the understanding of the setting chemistry and final structure of glass-poly(alkenoate) [‘Glass-Ionomer’] cements has been carried out in which the decomposition of
The properties of a glass polyalkenoate (ionomer) cement incorporating sintered metallic particles.
Effect of varnishes and other surface treatments on water movement across the glass-ionomer cement surface.
A further series of surface treatments has been tested and it has been shown that immediate covering of the immature glass ionomer cement surface with light-activated bonding resin is the most effective method of limiting water movement across the surface.
Changes in compressive strength of glass ionomer restorative materials with respect to time periods of 24 h to 4 months.
It was found that, over the period of 24 h to 4 months, some materials, namely those based on polyacrylic acid, maintained or even showed a slight increase in their strength, whereas others based on copolymers of acrylic acid first increased in strength, but thereafter showed deterioration.

Resin-modified glass-ionomer cements have the advantage of a long working time combined with a rapid set and higher early strength, and they are also easily bonded to resins, but they share with composite resins the disadvantage of containing free monomers and therefore may not be as biocompatible as conventional glass-ionic cements.
Fourier Transform Infrared Spectroscopic Study of the Role of Tartaric Acid in Glass-ionomer Dental Cements
(+) - Tartaric acid is incorporated into glass-ionomer dental cements to control the setting characteristics. FTIR has been used to examine the cements as they set, and has confirmed previous results
Hydrogels in Biomedical Applications
The patient literature relating to contact lenses is reviewed and the development of the composition of hydrogel materials is thereby traced and compared with the range of lens materials currently available.
Medical and Pharmaceutical Applications of Water Soluble Polymers
The use of hydrophilic polymers in medicine and pharmacy cannot be regarded as of recent origin, but it is only in the last 30 years or so that the potential of custom made synthetic products has
Water Sensitive Chemically Cross-Linked Gels
The principal properties and available information on hydrogels prepared by synthetic methods are reviewed. Hydrogels made from natural polymers are not discussed.
