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.

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.

Glass ionomer cements and dental pulp

Dental Traumatology, 1991
Abstract 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, 1990
Four 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, 1979
The 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 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.

Biological Evaluation on Glass Ionomer Cement

Journal of Dental Research, 1979
Biological properties of a new dental cement of glass ionomer cement were compared with other types of conventional cement. The biological test was carried out by tissue culture method and animal examination. The culture cells showed weaker reaction to the glass ionomer cement than zinc oxide-eugenol or polycarboxylate cement.

Glass ionomer cements

2021
Glass ionomer cements (GICs) are hydrophilic, bioactive restorative materials which develop their structure and harden following an acid-base reaction of the powder and the liquid. The GIC powder is an acid-soluble calcium fluoroaluminosilicate glass and its liquid part is an aqueous solution of organic acids, i.e.

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.
