Designing Calcium Silicate Cements with On-Demand Properties for Precision Endodontics

Journal of Dental Research, 2023
Calcium silicate (C3S) cements are available in kits that do not account for patients’ specific needs or clinicians’ preferences regarding setting time, radiopacity, mechanical, and handling properties. Moreover, slight variations in powder components and liquid content affect cement’s properties and bioactivity.

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 ...

Cytotoxicities and genotoxicities of cements based on calcium silicate and of dental formocresol

Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2017
Increasing interest is being paid to the toxicities of dental materials. The purpose of this study was to determine the cytotoxicities and genotoxicities of endodontic compounds to Chinese hamster ovary (CHO-K1) reproductive cells. Cultured CHO-K1 cells were treated with dental formocresol, two types of calcium hydroxide paste, and two types of mineral

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.

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.

Evaluation of the radiopacity of calcium silicate cements containing different radiopacifiers

International Endodontic Journal, 2009
AbstractAim  To identify the suitable ratio of alternative radiopacifiers to impart the necessary radiopacity to calcium silicate cements (CSC) and assess the purity of the radiopacifying agents.Methodology  Alternative radiopacifying materials for incorporation into CSC included barium sulphate, titanium oxide, zinc oxide, gold powder and silver/tin ...

Physicochemical properties of calcium silicate cement based endodontic sealers

Journal of the Mechanical Behavior of Biomedical Materials
To mensure the physicochemical properties of three ceramic cement endodontic sealers AH Plus Bioceramic, Bio-C Sealer and Bio-C Sealer Ion+ with an epoxy resin sealer, AH Plus.These properties were measured: hardening time (HT), dimensional change (DC), solubility (SL), flow (FL) and radiopacity (RD).
