The Hydration of Dental Cements [PDF]
Journal of Dental Research, 1979 A study was made of the hydration of dental cements, water being classified as "non-evaporable" and "evaporable". The ratio of these two types of water was found to vary greatly among different cement types, being lesser in zinc oxide and ionic polymer cements and greater in ion-leachable glass and phosphoric acid cements.

The properties of four dental cements [PDF]
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 ...

Cytotoxicity of four categories of dental cements [PDF]
Dental Materials, 2009 Objectives: Assessment of dental material biocompatibility is gaining increasing importance for both patients and dentists. Dental cements may be in contact with oral soft tissues for prolonged periods of time and play an important role in prosthetic ...

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 ...

Journal of Esthetic and Restorative Dentistry, 2007
Selection of the appropriate dental cement when delivering an indirect restoration is vital to the success of the treatment. This task has become a challenge, considering the different types of luting agents available and the increasing number of different restorative options.

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. This test

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.

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.

Formation of Dental Silicate Cement
Nature, 1970THE 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.
