Biocompatibility of glass ionomer cements
Biomaterials, 1993Glass 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 ...

Leaching from glass ionomer cements
Journal of Oral Rehabilitation, 1994SummaryThis 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

Reactive fibre reinforced glass ionomer cements
Biomaterials, 2003The mechanical properties of glass ionomer cements used in restorative dentistry reinforced by chopped glass fibres were investigated. Reactive glass fibres with a composition in the system SiO(2)-Al(2)O(3)-CaF(2)-Na(3)AlF(6) and a thickness of 26 microm were drawn by a bushing process.

Ion processes in glass ionomer cements
Journal of Dentistry, 2006Ion 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.

Opacity of glass-ionomer cements
Acta Odontologica Scandinavica, 1983The 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.

Glass ionomer cements and dental pulp
Dental Traumatology, 1991Abstract Only slight pulp reactions to glass ionomer cements occurred when inserted in Class V cavities of dog teeth. Most inflammatory reactions were due to bacteria at the tooth/filling interface. Special dentin reactions were noted in almost half the teeth, including hematoxyphilic bands in the dentin and a disturbance of the mineralization pattern ...

Finishing and polishing glass-ionomer cements
Acta Odontologica Scandinavica, 1990Four different methods for finishing and polishing the surfaces of two different glass-ionomer cements were studied by measuring the roughness of specimens at different stages of the procedures. Method 1 consisted of the four 3M Sof-Lex XT discs. Method 2 included a round, fine-grit diamond and the Vivadent polisher.

Dowel retention with glass-ionomer cement
The Journal of Prosthetic Dentistry, 1979The retentive capacity of the Whaledent Parapost system utilizing ASPA cement was compared at two lengths, three diameters, and with respect to the effect of both medication and citric acid pretreatment. The greatest single factor influencing retention was embedment depth into dentin.

Glass polyalkenoate (glass-ionomer) cements: a review
Journal of Dentistry, 1986Abstract This paper reviews the history and development of glass polyalkenoate (glass-ionomer) cements from their inception at the Laboratory of the Government Chemist during the 1960s to the present day.
