Chemistry of glass-ionomer cements: a review

Biomaterials, 1998
Studies of the setting of glass-ionomer cements have been carried out for over twenty years, and there is now a considerable body of information concerning the steps that lead to the conversion of a freshly mixed cement paste into a solid, durable dental restorative. This paper reviews these studies, paying particular attention to more recent work. The

Glass Ionomer Cements: Chemistry of Erosion

Journal of Dental Research, 1976
A three-month study of the chemistry of the water erosion of two forms of ASPA cement has been made. The effect of varying cement consistency and cure time was investigated. The results are discussed in terms of the known chemistry and structure of the cement.

The bonding of glass ionomer cements to caries-affected primary tooth dentin.

Pediatric Dentistry, 2013
PURPOSE The purpose of this study was to evaluate the bonding of glass ionomer cements (GICs) to sound and caries-affected dentin by microtensile bond strength (μTBS) and nanoleakage (NL) tests.

Wear and Microhardness of Glass-Ionomer Cements

Journal of Dental Research, 1987
Pin-and-disc wear and Knoop Hardness measurements were made on three commercial glass-ionomer cements having slightly different compositions. The specific objective was to determine whether these cements have potential for use in posterior teeth, and, if not, what modifications in composition and structure would be appropriate to enhance their ...

Biological evaluation of glass ionomer cements [PDF]

International Endodontic Journal, 1986
Summary. Sixty human premolar and canine teeth were used in this study. Class V cavities were prepared with a turbine handpiece. The experimental material was ASPA, with silicate cement and zinc oxide‐eugenol cements being used as controls. The teeth were extracted approximately 4 days, 30 days or 90 days after insertion of the filling material.

Composition and Characteristics of Glass Ionomer Cements

The Journal of the American Dental Association, 1990
Glass ionomer cement materials are currently available for restoration, cavity lining and basing, luting, and preventive applications. The in vitro performance is a function of composition, manipulation, and placement. In general, the cements may be characterized as strong, stiff, hard materials that are adhesive to calcified tissue, have low toxicity,
