Calcium silicate and calcium aluminate cements for dentistry reviewed

Journal of the American Ceramic Society, 2021
Abstract 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 ...

Volume of Voids in Retrograde Filling: Comparison between Calcium Silicate Cement Alone and Combined with a Calcium Silicate–based Sealer

Journal of Endodontics, 2020
INTRODUCTION: The aim of this study was to compare the volume of voids between retrograde filling using calcium silicate cement alone and retrograde filling using a combination of calcium silicate cement with a calcium silicate-based sealer. METHODS:

Nanostructure of Calcium Silicate Hydrates in Cements

Physical Review Letters, 2010
Calcium 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, 2018
A 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.

Physicochemical and Biological Properties of Mg-Doped Calcium Silicate Endodontic Cement

Materials, 2021
Calcium silicate-based cement has been widely used for endodontic repair. However, it has a long setting time and needs to shorten setting time. This study investigated the effects of magnesium (Mg) ion on the setting reaction, mechanical properties, and

Development of calcium silicate/calcium phosphate cement for bone regeneration

Biomedical Materials, 2007
A 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

Calcium Phosphate Silicate and Calcium Silicate Cements Suppressing Osteoclasts Activity Through Cytokine Regulation

Journal of Nanoscience and Nanotechnology, 2018
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, 2007
Although 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 ...

The use of calcium-silicate cements to reduce dentine permeability

Archives of Oral Biology, 2012
To evaluate in vitro the effectiveness of different calcium-silicate (CS) cements specifically designed for dentine permeability reduction.Fifty dentine discs were prepared from caries free human molars extracted for surgical reasons. The treatment consisted in applying two different experimental CS cements on dentine surface.
