The properties of four dental cements
Australian Dental Journal, 1975Abstract— Tests on 4 cements showed no significant difference in the retentive property of zinc phosphate and polycarboxylate cements but significant differences existed between these and two zinc oxide eugenol (modified) materials. Polycarboxylate cement was the only material which fractured partially or wholly within the cement film and the zinc ...

Initial acidity of dental cements
European Journal of Oral Sciences, 1984Abstract – The acidity in aqueous solutions following release of acid components from glass ionomer, silicate, zinc phosphate and zinc polycarboxylate cements has been registered by pH measurements. One brand of each type was studied. Initial setting was accomplished at two different temperatures; 23°C and in the interval from 23°C to about 60°C.

Early erosion of dental cements
European Journal of Oral Sciences, 1984Abstract –The disintegration in water of various unset glass ionomer cements, a polycarboxylate and a zinc phosphate cement was measured gravimetrically after exposure of the cements to a constant water jet. The test gave reproducible results with significant variations between the various types and brands of cements.

Medical and dental applications of cements
Journal of Biomedical Materials Research, 1971AbstractA number of cements based upon polymeric systems are being utilized in both medical and dental fields. The polymethyl methacrylate rapid polymerizing monomerpolymer materials have undergone extensive development as dental materials and are used widely also for rentention of orthopedic prostheses.

Dental cements: a comparison of properties
The Journal of the American Dental Association, 1963An analysis of various types of dental cements from the standpoint of minimiz ing patient discomfort indicates that zinc oxide-eugenol cement is decidedly su perior. Although the solubility of this cement is low and its initial*adaptation to the cavity walls unusually good, its low strength and lack of resistance to abra sion confine its use to ...

Dental Cements: Reactor Response
Advances in Dental Research, 1988This paper is in response to Dr. Dennis Smith's paper, which dealt with the current status of dental cements and recommendations with respect to future research needs. Interest in cements and research in this area have mushroomed with the development of polycarboxylate and glass-ionomer cements.

Porosity of different dental luting cements
Dental Materials, 2007The aim of this in vitro study was to compare open porosity and pore size distribution of different types of luting cements (zinc phosphate and polycarboxylate produced by Harvard Cement, Great Britain, glass-ionomer product GC Fuji I, GC Corporation, Japan, and Panavia F, resin based composite cement, Kurraray Co. Ltd.

High modulus nanopowder reinforced dimethacrylate matrix composites for dental cement applications.
Journal of Biomedical Materials Research. Part A, 2007Results from the study of a novel, high modulus nanopowder filled resin composite are presented. This composite is developed to serve (1) as a high stiffness support to all-ceramic crowns and (2) as a means of joining independently fabricated crown core ...

Development of novel dental cements. II. Cement properties
Clinical Materials, 1992Following earlier work, three novel aluminoborate glasses have been studied as potential cement components. Factors studied include the effect of batch size on composition and manipulative characteristics, and the effect of tartaric acid and conditions of storage on mechanical properties.
