Evaluation of tissue response of experimental calcium silicate‐based endodontic sealers: An in vivo study

European Journal of Oral Sciences, EarlyView.
Abstract The aim of this study was to evaluate whether the experimental sealers, composed of tricalcium silicate (CaSi) and CaSi supplemented with calcium hypochlorite (CaSi‐H), stimulate tissue repair. The tissue response of experimental materials was compared with commercially available materials Bio‐C sealer (BC sealer) and BioRoot (BROOT ...

Improving the Radiopacity of Calcium Aluminate Cement Based Blends [PDF]

Materials Research, 2018
The radiopacity of CAC-based compositions containing additives (ZnO, Ag and Bi2O3) was evaluated by optical density measurements, cold crushing strength, apparent porosity, pore size distribution, in vitro apatite-formation ability (bioactivity) and cell

Hydraulic fast‐setting calcium silicate cement for crown cementation

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluated film thickness, diametral tensile strength (DTS), and crown retentive strength of hydraulic fast‐set calcium silicate cement (fast‐set CSC) compared to conventional luting cements. Materials and Methods Fast‐set CSC was compared to zinc phosphate cement and glass ionomer cement.

Characterization and separation resistance of an in-situ 2D nanocarbon/calcium aluminate composite synthesized via a combustion method

Journal of Asian Ceramic Societies, 2021
In-situ 2D nanocarbon/calcium aluminate composite (NCAC) was synthesized via a combustion method designed based on aluminothermic reduction using calcium carbonate (CaCO3) as carbon source. The results demonstrate that compared with the pristine product,

The use of Bioceramics as root-end filling materials in periradicular surgery: a literature review [PDF]

, 2018
Introduction: Periradicular surgery involves the placement of a root-end filling following root-end resection, to provide an apical seal to the root canal system. Historically several materials have been used in order to achieve this seal.

Semidiaphanam Tremuli Narcissuli Ideam Lacteam1: Ehrenfried Walther von Tschirnhaus (1651–1708) and His Determined Search for the Porcelain Principle

Archaeometry, Volume 68, Issue 1, Page 120-131, February 2026.
ABSTRACT With this contribution, an attempt is being made to chart the timeline of the invention of the European hard‐paste porcelain based on historical documents. They were evaluated to trace the development lines from Tschirnhaus's early experiments with burning mirrors and lenses in the 1680s to finding ‘wax porcelain’ around 1694 to the ...
