Evaluating the Efficacy of Bioceramic versus Resin-Based Sealers in Endodontic Treatments: A Comparative Analysis

Journal of Pharmacy and Bioallied Sciences
Background: Root canal therapy relies heavily on the effectiveness of the sealer used to ensure successful treatment outcomes. Bioceramic and resin-based sealers are commonly employed, each offering distinct advantages and drawbacks.

Antimicrobial activity of root canal sealers [PDF]

Stomatoloski glasnik Srbije, 2006
All root canal sealers should have antimicrobial activity so that they could act against any remaining bacteria after root canal obturation. The aim of this study was to evaluate the antimicrobial activity of five root canal sealers: AH26, a resin based paste; Apexit, calcium hydroxide based paste; Endomethasone and Tubliseal, zinc oxide eugenol based ...

Allogeneic Immune Cell Perfusion Inhibits the Growth of Vascularized 3D In Vitro Tumor Models, Induces Vascular Regression and Desmoplasia, but Promotes Tumor Cell Invasion

Advanced Science, EarlyView.
This study presents a vascularized 3D tumor model to investigate immune–stromal–tumor interactions under allogeneic PBMC perfusion. While immune cells induced tumor shrinkage, they also promoted vascular regression, stromal activation, and cancer cell invasion.

Catechol Derivative‐Based Bioadhesives: Molecular Design for Precision Medical Adhesion

Advanced Science, EarlyView.
This study utilizes tree‐inspired side‐chain engineering to graft five catechol derivatives onto PVA, systematically revealing how side‐chain length and substituents regulate adhesion and cohesion properties. Among them, the PVA‐CA patch demonstrates superior tissue adhesion, biocompatibility, and promotes regeneration, establishing a programmable ...

Water uptake and solubility of Acroseal sealer in comparison with Apexit and AH Plus sealers in Hank’s solution [PDF]

, 2011
Introduction. The function of root canal fillings is to seal the root canal system. The important physical property necessary for sealers to achieve this is low solubility.

Tunable Sound Absorption via Evanescent‐Wave Coupling in Asymmetric Bilayer Metasurfaces

Advanced Science, EarlyView.
Tunable sound absorption is realized through a bilayer metasurface system governed by evanescent‐wave coupling. This work demonstrates that such evanescent‐wave coupling provides a controllable scattering channel that destructively interferes with the specular reflection.

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, EarlyView.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.
