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.

Effect of Cold Plasma on the Penetration Depth of AH26 and Beta Resin Sealers in Dentinal Tubules [PDF]

Journal of Dentistry
Statement of the Problem: The creation of a proper seal of the root canal with canal-filling materials, such as gutta-percha and sealer, is one of the essential factors in the success of root canal treatment.

Stereomicroscopic Dye Leakage Measurement of Six Different Root Canal Sealers [PDF]

Journal of Clinical and Diagnostic Research, 2017
Introduction: Hermetic sealing of the root canal is the most desirable outcome of any root canal treatment, but almost always the filling of the root canal is defective, which is a multifactorial outcome.

Effect of eugenol-based endodontic sealer on the adhesion of intraradicular posts cemented after different periods [PDF]

, 2009
OBJECTIVE: This study evaluated in vitro the influence of an eugenol-based sealer (EndoFill) on the retention of stainless steel prefabricated posts cemented with zinc phosphate and resin-based (Panavia F) cements after different periods of root canal ...

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 ...

A novel root canal filling technique using a resin-based sealer without gutta-percha: a summary of two cases

BMC Oral Health
Objectives Root canal filling is a fundamental step in non-surgical root canal treatment (RCT), required to prevent reinfection or new infection within the root canal system. Traditionally root canal filling uses a sealer in combination with gutta-percha

Evaluation of single root canals filled using the lateral compaction, tagger's hybrid, microseal and guttaflow techniques [PDF]

, 2010
The aim of this study was to determine the percentage of voids, gutta-percha and root canal sealer using 4 different filling techniques. Fifty-two extracted maxillary lateral incisors were prepared using the crown-down pressureless technique.

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.

Correlation between Microleakage and Tubules Penetration of an Endodontic Sealer [PDF]

, 2013
Objective: The aim of the study was to verify the existence of a correlation between fluid filtration and tubular penetration of an endodontic sealer.

Clinical utility index for root canal sealers

BMC Oral Health
Abstract Background Effective endodontic treatment requires the use of a root canal sealer with optimal properties to ensure a hermetic seal, prevent reinfection, and promote healing. Despite the availability of various sealers, a standardized evaluation system still needs to be improved ...
