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, 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 ...

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.

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 ...

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

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 ...

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 ...

Novel calcium phosphate coated calcium silicate-based cement: in vitro evaluation

Biomedical Materials, 2020
Calcium silicate-based cements are known for their wide applications in dentistry and orthopedics. The alkaline pH (up to 12) of these cements limits their application in other orthopedic areas. In this study, the effect of dicalcium phosphate dihydrate (DCPD) coating on set cement on pH reduction and biocompatibility improvement was examined.

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.

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.
