Glass ionomer cements in orthodontics—An update

American Journal of Orthodontics and Dentofacial Orthopedics, 1988
Because conventional bands continue to be used in clinical orthodontics, it is essential to evaluate new dental cements to establish their suitability as a cementing medium for orthodontic bands. This study was undertaken to determine the failure rate of bands cemented with a glass ionomer cement to premolar and molar teeth. The sample consisted of 100

Depth microhardness of glass ionomer cements

Biomaterials, 1996
The purpose of this study was to observe the effect of different conditions of storage on the surface and in the depth of luting glass ionomer cement by measuring microhardness. The hardness of a glass ionomer cement was measured after storage in wet and dry conditions and in an atmosphere of 80% relative humidity, for times up to 1000 h.

Microleakage of glass ionomer cement composite resin and glass ionomer resin cement.

The Journal of clinical pediatric dentistry, 1998
An in vitro dye leakage study was performed to compare the sealing ability of glass ionomer, composite resin and glass ionomer/resin cement when used as restorative materials for G. V. Black class V cavities. In this research, standard Class V cavities were prepared in sound premolar teeth extracted for orthodontic reasons.

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.

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.

Biocompatibility of glass-ionomer bone cements

Journal of Dentistry, 2006
Glass-ionomer cements (GIC) have been extensively used in dentistry for over 30 years. Due to their excellent biocompatibility in dental applications GIC have been formulated for medical applications. The past decade has seen some impressive advances in the development of medical GICs, however these advances have been matched by serious critical ...

Development of glass-ionomer cement systems

Biomaterials, 1998
In the 1960s the idea of positive physico-chemical adhesion with tooth substance resulted in the invention of polyacrylic acid-based cements, first the zinc polycarboxylate and, subsequently, the glass-ionomer cements. These materials were shown to undergo specific adhesion with hydroxyapatite and proved to have properties satisfactory for a variety of
