Ettringite Seeds for Strength Enhancement: Novel Synthesis via One‐Step Co‐Precipitation

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Reduced early strength can be a barrier to the adoption of cements blended with high levels of limestone. Chemical admixtures based on nucleation seeding are emerging as a potential solution. Herein, while synthesis of C‐S‐H‐based seeds has been thoroughly investigated in the literature, there are limited synthesis protocols available on other

In Vitro Evaluation of Novel Calcium Silicate‐Based and Resin‐Modified Calcium Silicate Materials: Cytocompatibility and Mineralization Potential on Human Dental Pulp Stem Cells for Pulp Repair

Microscopy Research and Technique, Volume 89, Issue 6, Page 932-947, June 2026.
This study demonstrates that Biodentine XP exhibits superior cytocompatibility, promotes odontogenic differentiation, and enhances mineralization in human dental pulp stem cells, supporting its use in regenerative endodontics. Resin‐modified materials showed lower bioactivity, highlighting the importance of material composition in pulp therapy outcomes.

Zinc polycarboxylate dental cement for the controlled release of an active organic substance: proof of concept

, 2009
The potential of employing zinc polycarboxylate dental cement as a controlled release material has been studied. Benzalkonium chloride was used as the active ingredient, and incorporated at concentrations of 1, 2 and 3% by mass within the cement.

Erosion Process of a Dental Polycarboxylate Cement

Journal of the Ceramic Association, Japan, 1987
Erosion process of the zinc polycarboxylate cement in various acid solutions was investigated by means of determination of Zn and Mg leached from the cement and SEM observation of the surface structure. The amount of species leached from the cement increased with increasing dissociation constant of the acid, that is, with decreasing pH of the solution.
