A hybrid zinc–calcium–silicate polyalkenoate bone cement

Biomaterials, 2003
A novel bone cement composed of sintered zinc-calcium-silicate phosphate and hybrid polyalkenoates has been developed. Synthesis and formulation of glass fillers, monomers and polymers as well as formulation of the cement were described. The effects of sintering, polymer content, glass powder/polymer liquid (P/L) ratio and comonomer on compressive ...

Physicochemical Properties of Calcium Silicate Cements for Endodontic Treatment

Journal of Endodontics, 2009
The purpose of this study was to examine the physicochemical properties of novel calcium silicate cements (CSCs) prepared by using a sol-gel method.The compressive strength, morphology, and phase composition of various cements were evaluated after mixing with water, in addition to setting time and pH value.As solid phases, the sol-gel-derived powders ...

Vinylphosphonic acid-modified calcium aluminate and calcium silicate cements

Journal of Materials Science, 1996
Cementitious materials in terms of calcium phosphate cements (CPC) were prepared through the acid-base reaction between vinylphosphonic acid (VPA) and calcium aluminate cement (CAC) reactants or calcium silicate cement (CSC) reactants at 25 °C. Using CAC, two factors were responsible for the development of strength in the cements: one is the formation ...

The change in reactivity of silicate anions during the hydration of calcium silicates and cement

Cement and Concrete Research, 1973
Abstract The change in reactivity of the silicate anion complex of tricalcium silicate, β-dicalcium silicate and portland cement during hydration was studied by measuring the rate constant ( k ) of the silicomolybdic acid formation. The three anhydrous starting materials have identical k values indicating their identical monosilicate anion ...

Effect of a Calcium-silicate-based Restorative Cement on Pulp Repair

Journal of Dental Research, 2012
In cases of pulp injury, capping materials are used to enhance tertiary dentin formation; Ca(OH) 2 and MTA are the current gold standards. The aim of this study was to evaluate the capacity of a new calcium-silicate-based restorative cement to induce pulp healing in a rat pulp injury model ...

Calcium polyphosphate as an additive to zinc-silicate glass ionomer cements

Journal of Biomaterials Applications, 2015
Aluminum-free glass ionomer cements (GICs) are under development for orthopedic applications, but are limited by their insufficient handling properties. Here, the addition of calcium polyphosphate (CPP) was investigated as an additive to an experimental zinc-silicate glass ionomer cement.

Calcium silicate‐based cements: composition, properties, and clinical applications

Journal of Investigative and Clinical Dentistry, 2015
AbstractMineral trioxide aggregate (MTA) is a calcium silicate‐based cement (CSC) commonly used in endodontic procedures involving pulpal regeneration and hard tissue repair, such as pulp capping, pulpotomy, apexogenesis, apexification, perforation repair, and root‐end filling.
