Synchrotron x-ray pair distribution function: A tool to characterize cement gels [PDF]

, 2018
Cement matrices contain large amounts of crystalline phases jointly with amorphous and/or nanocrystalline phases. Consequently, their analyses are very challenging.

Effect of Endodontic Sealers on the Bond Strength of Glass Fibre Posts: A Systematic Review

Australian Endodontic Journal, EarlyView.
ABSTRACT This systematic review evaluated the influence of resin‐based, eugenol‐based and bioceramic endodontic sealers on the bond strength of glass fibre posts cemented with resin cements. Searches were conducted in PubMed, Scopus, Web of Science, Cochrane Library, Google Scholar and Embase, including in vitro studies using human or bovine teeth ...

Pair distribution function studies in cementitious systems [PDF]

, 2017
The analysis of amorphous/nanocrystalline phase(s) within cement matrices that contain high amounts of crystalline phase(s) is very challenging. Synchrotron techniques can be very useful to characterize such complex samples.1 This work is focused on ...

Enterococcus faecalis and Endodontic Treatment Failure: A Qualitative Systematic Review of Its Role and Elimination Strategies

Australian Endodontic Journal, EarlyView.
ABSTRACT The aim of this study was to synthesize evidence on the influence of Enterococcus faecalis on endodontic treatment failure and strategies for its elimination. This study followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines and was registered in PROSPERO (CRD420251022741).

Glass Polyalkenoate Cements Designed for Cranioplasty Applications: An Evaluation of Their Physical and Mechanical Properties

Journal of Functional Biomaterials, 2016
Glass polyalkenoate cements (GPCs) have potential for skeletal cementation. Unfortunately, commercial GPCs all contain, and subsequently release, aluminum ions, which have been implicated in degenerative brain disease. The purpose of this research was to

Efficacy of the Biomaterials 3 wt%-nanostrontium-hydroxyapatite-enhanced Calcium Phosphate Cement (nanoSr-CPC) and nanoSr-CPC-incorporated Simvastatin-loaded Poly(lactic-co-glycolic-acid) Microspheres in Osteogenesis Improvement [PDF]

, 2016
Aims The purpose of this multi-phase explorative in vivo animal/surgical and in vitro multi-test experimental study was to (1) create a 3 wt%-nanostrontium hydroxyapatite-enhanced calcium phosphate cement (Sr-HA/CPC) for increasing bone formation and (2)

Symmetry induced stability in alkali doped calcium-silicate-hydrate

, 2018
CO$_2$ emissions originating from the construction industry have a significant impact on global warming where the production of ordinary Portland cement clinker is responsible for approximately 8\% of all human-made CO$_2$.

Crystalline phases involved in the hydration of calcium silicate-based cements: Semi-quantitative Rietveld X-ray diffraction analysis [PDF]

, 2017
Chemical comparisons of powder and hydrated forms of calcium silicate cements (CSCs) and calculation of alterations in tricalcium silicate (Ca3SiO5) calcium hydroxide (Ca(OH)2) are essential for understanding their hydration processes.

Knowledge and Perceptions of Preformed Metal Crowns and Pulpotomies in Primary Molars Amongst Dental Students in Amsterdam, the Netherlands—A Questionnaire‐Based Cross‐Sectional Study

European Journal of Dental Education, EarlyView.
ABSTRACT Introduction Preformed metal crowns (PMCs) and pulpotomies are established treatments for carious lesions in primary molars. Despite their effectiveness, variability in knowledge and clinical experience amongst dental students has been reported. This study aimed to evaluate the knowledge and perceptions of Dutch dental students at the Academic

Microstructural characterization of CO2-cured calcium silicate cement

Developments in the Built Environment
Calcium silicate cement (CSC) is a non-hydraulic cement that solidifies in moist conditions with CO2 curing. To contribute to the standardization of CSC, the material has been produced locally, and the microstructural characterization of the carbonation products of CSC samples with water-to-cement (W/C) ratios of 0.35, 0.4 and 0.45 at 10% CO2 ...
