Heat treatment of glass ionomer, silicate, zinc phosphate and zinc polycarboxylate cements

European Journal of Oral Sciences, 1982
Abstract – The compressive strength and erosion resistance of glass ionomer, silicate, zinc phosphate or zinc polycarboxylate cements, submitted to heat treatments at 50° or 70°C after mixing, have been assessed. Zinc phosphate cement specimens showed a marked reduction in compressive strength properties and erosion resistance, while minor ...

Effects of a 36% tooth bleaching gel on zinc phosphate cement

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2009
AbstractPurpose: To assess the effect of a 36% hydrogen peroxide bleaching gel on the roughness, microhardness, indentation modulus, and micromorphology of zinc phosphate cement aged 24 h or 1 week, compared to cement not exposed to bleaching gel. Methods: Dynamic indentation was performed for microhardness and indentation modulus. Contact profilometry

A comparison of the in vitro retentive strength of glass-ionomer cement, zinc-phosphate cement, and mineral trioxide aggregate for the retention of prefabricated posts in bovine incisors.

Journal of Endodontics, 2004
The purpose of this study was to compare the retentive strength of zinc-phosphate cement, glass-ionomer cement, and mineral trioxide aggregate (MTA) cement in the retention of prefabricated posts.

A comparison between zinc phosphate and glass ionomer cement in orthodontics

American Journal of Orthodontics and Dentofacial Orthopedics, 1988
In the past orthodontic band cementation has relied heavily on mechanically retentive cements such as zinc phosphate luting agents. The clinical performance of a glass ionomer cement (GIC), a chemically retentive cement, was evaluated against a conventional zinc phosphate cement (ZP).

The flow properties of zinc phosphate cement: An argument for changing the Standard

Australian Dental Journal, 1980
Abstract— The flow properties of a typical zinc phosphate cement used for luting purposes were determined. These properties differed significantly from those of a Standard and a base‐forming mix. An argument is presented for changing the Standard for zinc phosphate cement to recognize the different clinical uses of the material.

Powder enrichment effects on film thickness of zinc phosphate cement

The Journal of Prosthetic Dentistry, 1979
The effects of powder erichment and subambiant mixing temperatures on the film thickness of three zinc phosphate cements were measured by two methods. A decrease in film thickness accompanied reduced mixing temperatures and standard powder-liquid ratios.
