Biocompatibility of glass ionomer cements

Biomaterials, 1993
Glass ionomer cements (GICs) are widely used in the dental field and are increasingly being considered as materials with potentially good osteogenic properties. This paper details a comprehensive biocompatibility evaluation of a number of GICs. These include conventional, commercially available materials, novel formulations and a new light cured ...

Opacity of glass-ionomer cements

Acta Odontologica Scandinavica, 1983
The translucency of the first generation of glass-ionomer cements to appear on the market was too low to be cosmetically satisfactory. In the present study the opacity of newer editions of glass-ionomer cements was evaluated and compared with that of a well-known composite resin.

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

The Journal of clinical pediatric dentistry, 1997
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.

Evaluation of the ability of glass-ionomer cement to bond to glass-ionomer cement.

Operative dentistry, 1990
This study investigated the cohesive bond strengths of glass-ionomer cement at three setting and etching intervals and compared these bonds to the shear strength of the material itself. Bonded cylinders were created and then sheared using the Instron Universal Testing Machine.

Spheroidization of glass powders for glass ionomer cements

Biomaterials, 2004
Commercial angular glass powders were spheroidized using both the flame spraying and inductively coupled radio frequency plasma spraying techniques. Spherical powders with different particle size distributions were obtained after spheroidization. The effects of spherical glass powders on the mechanical properties of glass ionomer cements (GICs) were ...

Glass ionomer cements: dispensing and strength

Australian Dental Journal, 1985
Abstract— The use of the powder and liquid dispensers provided by the manufacturers to achieve an optimal mix of glass ionomer cement was examined. The dispensers should be regarded only as an approximate guide to the ratio of powder and liquid required.

Leaching from glass ionomer cements

Journal of Oral Rehabilitation, 1994
SummaryThis study compared the electrical conductivities, pH and leached ion (F−, Ca, Al, Si) concentrations in supernatant liquids obtained from four glassionomer cements, a buffered ionomer cement, a polycarboxylate cement and a zinc phosphate cement, at three different levels of settings. The result indicated that the measured parameters are highest

Ion processes in glass ionomer cements

Journal of Dentistry, 2006
Ion processes are involved in many aspects of glass-ionomer cements. The ions released from the glass take part in the formation of the cement matrix. Although this process has been investigated, particularly using model cement systems, no study provides a complete matrix composition.

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 ...
