Formation of Dental Silicate Cement

Nature, 1970
THE setting of dental silicate cement, a material widely used as an anterior tooth filling1, is generally attributed to the formation of silica gel2. Its potentially high strength (< 3,000 kg/cm2) compared with known silica gel cements3 (150–270 kg/cm2) is, however, at variance with this view.

The tableting of dental cement powders

Journal of Dentistry, 1975
Abstract Preproportioned quantities of dental cement powders may be useful in obtaining correct powder: liquid ratios. Some dental cement powders have been investigated with regard to the feasibility of converting them into tablets to achieve this aim.

The properties of four dental cements

Australian Dental Journal, 1975
Abstract— 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 ...

Early erosion of dental cements

European Journal of Oral Sciences, 1984
Abstract –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, 1971
AbstractA 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, 1963
An 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

2022
Dental cements have been used in everyday clinical practice for years. They are used for permanent or temporary cementation of fixed prosthetic restorations, as cavity liners and for temporary or permanent fillings. They should have appropriate properties such as biocompatibility, pulp protection, bacteriostatic action, good rheological, esthetic and ...

Dental Cements: Reactor Response

Advances in Dental Research, 1988
This 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.
