Fibrillar calcium silicate hydrate seeds from hydrated tricalcium silicate lower cement demand [PDF]
Cement and Concrete Research, 2020 Abstract Debates remain on the influencing factor and long-term performance of C-S-H-seeded paste. In this study, phase-pure seeds were prepared from diluted Ca3SiO5 hydration. The seed structures were determined using synchrotron-based X-ray diffraction, X-ray absorption spectroscopy, and transmission electron microscopy.

Ex Vivo Osteogenesis Induced by Calcium Silicate-Based Cement Extracts
Journal of Functional Biomaterials, 2023 Calcium silicate-based cements are used in a variety of clinical conditions affecting the pulp tissue, relying on their inductive effect on tissue mineralization. This work aimed to evaluate the biological response of calcium silicate-based cements with distinct properties—the fast-setting Biodentine™ and TotalFill® BC RRM™ Fast Putty, and the ...

Enhanced bioactivity of glass ionomer cement by incorporating calcium silicates [PDF]
Biomatter, 2016 Glass ionomer cements (GIC) are known as a non-bioactive dental cement. During setting the GIC have an acidic pH, driven by the acrylic acid component. It is a challenge to make GIC alkaline without disturbing its mechanical properties. One strategy was to add slowly reacting systems with an alkaline pH.
