Cone beam computed tomography – the importance of z-axis
Journal of Indian Academy of Oral Medicine and Radiology, 2019 Background: Conventional imaging is the backbone of dentistry. Intraoral and extraoral radiographs are commonly used for diagnosis and clinical management for multiple maxillofacial pathologies.

Cone beam computed tomography in oral implants
National Journal of Maxillofacial Surgery, 2013 Cone beam computed tomography (CBCT) scanners for the oral and maxillofacial region were pioneered in the late 1990s independently by Arai et al. in Japan and Mozzo et al. CBCT has a lower dose of radiation, minimal metal artifacts, reduced costs, easier accessibility, and easier handling than multislice computed tomography (MSCT); however, the latter ...

Advanced Healthcare Materials, EarlyView.Flexible, biocompatible PVDF nanofibers embedded with magnetite nanodiscs enable wireless magnetoelectric neuromodulation. Shape anisotropy of the nanodiscs facilitates magnetostrictive strain transfer under alternating magnetic fields, allowing activation of neurons in vitro and behavioral modulation in vivo, without requiring rigid implants or ...

Beyond Conventional Cooling: Advanced Micro/Nanostructures for Managing Extreme Heat Flux
Advanced Materials, EarlyView.This review examines the design, application, and manufacturing of biomimetic or engineered micro/nanostructures for managing high heat‐flux in multi‐level electronics by enhancing conductive, convective, phase‐changing, and radiative heat transfer mechanisms, highlighting their potential for efficient, targeted thermal management, and future prospects.

Advanced Materials, EarlyView.It is demonstrated that contact resistance is effectively eliminated in two‐probe micropore device metal/protein/metal bioelectronic junctions. These results, using two different protein types in these junctions, show that, as ultrathin (<40 nm) films, proteins are an even more efficient electronic transport medium than previously thought, when the ...

Fundamentals of cone beam computed tomography for a prosthodontist
The Journal of Indian Prosthodontic Society, 2015 Cone beam computed tomography (CBCT, also referred to as C-arm computed tomography [CT], cone beam volume CT, or flat panel CT) is a medical imaging technique of X-ray CT where the X-rays are divergent, forming a cone.[1] CBCT systems have been designed for imaging hard tissues of the maxillofacial region.

Advanced Materials, EarlyView.In this work, nonzero Berry curvature in photonic crystals is induced by breaking unit cell inversion symmetry through spatial shifts rather than geometrical modifications. This enables the design of ultraconfined topological states with subwavelength in‐plane field confinement and out‐of‐plane field isolation.

Features X-ray examinations during endodontic treatment
Эндодонтия Today, 2020 The study of the reliability display of root canals of all groups of teeth was carried out in the laboratory by 158 intraoral radiographs, 36 orthopantomogram, 1434 computer tomography. In clinical studies 127 patients analyzed 374 intraoral periapical x-
