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 ...

Calcium silicate and calcium aluminate cements for dentistry reviewed
Journal of the American Ceramic Society, 2021Abstract Calcium silicate cements were identified as excellent materials for dentistry, particularly for dental procedures contacting the dental pulp or root system. Both calcium silicate and calcium aluminate cements cause the biomineralization (precipitation of hydroxyapatite [HA] phenomena and shield dental tissues from the ...

Nanostructure of Calcium Silicate Hydrates in Cements
Physical Review Letters, 2010Calcium silicate hydrate (CSH) is the major volume phase in the matrix of Portland cement concrete. Total x-ray scattering measurements with synchrotron x rays on synthetic CSH(I) shows nanocrystalline ordering with a particle diameter of 3.5(5) nm, similar to a size-broadened 1.1 nm tobermorite crystal structure.

In vivo biocompatibility and biomineralization of calcium silicate cements
European Journal of Oral Sciences, 2018A new mineral trioxide aggregate (MTA) material has been developed with a modified composition that requires investigations to support its clinical use. This study evaluated the biocompatibility and biomineralization of this new MTA material and compared it with that of two other MTA cements over time.

Development of calcium silicate/calcium phosphate cement for bone regeneration
Biomedical Materials, 2007A new type of composite bone cement was prepared and investigated by adding calcium silicate (CS) to calcium phosphate cement (CPC). Low-crystalline CS prepared by heat treatment at low temperature had excellent bioactivity and degradability. Adding CS to CPC did not affect the phase composition and chemical structure of CPC, and had a little effect on

Inorganic cements for biomedical application: calcium phosphate, calcium sulphate and calcium silicate [PDF]
Advances in Applied Ceramics, 2015 Inorganic cements have found utility in tissue replacement since the late nineteenth century, one of the first examples being calcium sulphates in the augmentation of bone defects.

Calcium phosphate silicate bone cement (CPSC) can stimulate osteoblast proliferation and promote osteogenesis, but how CPSC supress osteoclast activity through cytokine regulation is not clear. In the current study, we synthesized CPSC by incorporating monocalcium phosphate (MCP) into calcium silicate cement (CSC), and analyzed the effects of CSC and ...

Composition and density of nanoscale calcium–silicate–hydrate in cement
Nature Materials, 2007Although Portland cement concrete is the world's most widely used manufactured material, basic questions persist regarding its internal structure and water content, and their effect on concrete behaviour. Here, for the first time without recourse to drying methods, we measure the composition and solid density of the principal binding reaction product ...
