A successful periodontal‐orthodontic treatment of an advanced case of dental trauma in a 9‐year‐old patient: A case report with 16‐year follow‐up

Clinical Advances in Periodontics, EarlyView.
Abstract Background Traumatic dental injury (TDI) most often requires complex and interdisciplinary management. Several factors are associated with the success of TDI treatment, including proper treatment planning and periodontal maintenance. Methods The present 16‐year follow‐up report describes the interdisciplinary management of an extrusive ...

Molecular Dynamics Simulations of γ‐Belite(010)–Water Interfaces With High‐Dimensional Neural Network Potentials

Chemistry – A European Journal, EarlyView.
Several γ$\gamma$‐belite(010)–water interfaces have been studied by molecular dynamics simulations using a high‐dimensional neural network potential. The structure and reactivity of interfacial water have been analyzed and two types of surface defects could be identified, which indicate the possible existence of a wide range of surface structures ...

Temperature‐dependent shear behavior and constitutive model of the rock–concrete interface

Deep Underground Science and Engineering, EarlyView.
Shear tests were conducted to investigate the temperature‐dependent shear behavior of the rock–concrete interface, highlighting the interaction between the surrounding rock and the lining during tunnel fires. Under experimental conditions, concrete exhibited greater temperature sensitivity than rock, with the shear fracture surface transitioning from ...

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs

Deep Underground Science and Engineering, EarlyView.
A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Osteogenic Potential of a Three-Phase Strontium- and Silicon-Doped Tricalcium Silicate Cement on Dental Pulp Stem Cells: An In Vitro Study. [PDF]

Clin Exp Dent Res
ABSTRACT Objective This study aimed to evaluate the osteogenic potential of a novel three‐phase cement composed of strontium‐doped hydroxyapatite (Sr‐HA), silicon‐doped hydroxyapatite (Si‐HA), and tricalcium silicate (C3S) on dental pulp stem cells (DPSCs) in vitro.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

A Reproducible SEM Surface Imaging Protocol for Monitoring Microstructural Changes During Gas–Rock Interactions

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Reliable characterization of mineralogical and textural changes in rock samples is essential for understanding fluid–rock interactions, particularly in experimental studies simulating subsurface conditions. This study presents a reproducible protocol for scanning electron microscopy (SEM) analysis of rock surfaces before and after exposure to ...
