Influence of silicate cement restorations on gingiva

The Journal of Prosthetic Dentistry, 1971
Abstract Anterior silicate restorations in 210 patients were examined to determine the effect of this material on gingival health. The following clinical observations were made. 1. Thirty-one per cent of the silicate restorations were found to be detective. 2. Silicate cement is a poor material for restoring contact. 3. The material should

The formation and microstructure of dental silicate cements

Journal of Materials Science, 1972
The chemistry of the cement-forming reaction between phosphoric acid solutions and fluorine-containing aluminosilicate glasses has been studied using a variety of physicochemical methods. These materials are the dental silicate cements and the microstructures of a number of these cements have been examined by optical, electron and scanning electron ...

Chemistry of colloidal silicates and cements

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1983
During the hydration of cement, colloidal particles are formed in the aqueous environment between the aggregate units. Their subsequent behaviour depends on the chemical nature of the particles and the additives present in the system. A review is given of the properties of colloidal particles likely to be present in the cement paste and the manner in ...

Water uptake and loss in silicate cements

Journal of Materials Science, 1982
The water absorption of a dental silicate cement was measured both in de-ionized water and in pH controlled phosphate buffers of several ionic strengths. Uptake is found to be related to ionic strength. Water loss was studied using thermogravimetry. Water loss is seen to be a continuous process from ambient temperatures to in excess of 500° C.

The effect of silicate cement on enamel and dentin

European Journal of Oral Sciences, 1974
abstract— The effects upon enamel and dentin of mixes of two different viscosities of silicate cement were examined by polarized light microscopy and microradiography. The silicate was applied to the cut surfaces of extracted teeth for periods of time ranging from 1 h to 2 weeks.

Stem cell differentiation-induced calcium silicate cement with bacteriostatic activity.

Journal of materials chemistry. B, 2015
Calcium-based bone cements are widely used in dental and orthopaedic surgery. Those based on calcium phosphate (CPCs) or calcium silicate (CSCs) have a number of favourable properties that encourage their clinical use in bone defect repair.

Dental Silicate Cements: V. Electrical Conductivity

Journal of Dental Research, 1968
The variation of the electrical conductivity of dental silicate cements with age is described, and the effects of varying temperature, powder-liquid ratio, and constitution of the liquid are discussed. A correlation with specification solubility is shown for a number of commercial brands.
