Dental Clinics of North America, 1971
The manifold uses of dental cements-as (a) luting agents, (b) cavity linings and bases, and (c) restorations for teeth—make them perhaps the most important materials in clinical dentistry. The research of the last 10 years has resulted in four main types, classified by matrix-forming species: (1) phosphate, (2) phenolate, (3) polycarboxylate, and (4 ...

The flow properties of dental cements
Journal of Biomedical Materials Research, 1980AbstractThe flow properties of several major types of dental cements were investigated using slow compressive strength and creep techniques. Considerable differences were found in their behavior. Whereas the phosphate‐bonded and glass‐ionomer cements exhibited brittle fracture, the other cements tended to distort to a greater or lesser extent under ...

An Erosion Test for Dental Cements
Journal of Dental Research, 1985A new method for the in vitro measurement of the erosion of dental cements is described which allows repeated, gentle removal of loose surface debris and provides a direct quantitative measurement of material lost. A linear relationship for erosion against time is demonstrated for a glass polyalkenoate material under mildly acidic conditions.

Antimicrobial action of dental cements
The Journal of Prosthetic Dentistry, 1980It was observed that some of the cements tested had bacteriostatic and/or bactericidal action. The cements listed in decreasing order of effectiveness are (1) zinc oxide-eugenol, (2) silicophosphate, (3) zinc phosphate, and (4) silicate. The two newer cements, polycarboxylate and composite resin, exhibited no measurable antimicrobial action.

The tableting of dental cement powders
Journal of Dentistry, 1975Abstract 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, 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 ...

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.

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.
