Electron Microscope Tomography and Single-particle Reconstruction

2.4K
Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Thin-Walled Hollow Shafts

176
In analyzing a thin-walled hollow shaft subjected to torsional loading, a segment with width dx is isolated for examination. Despite its equilibrium state, this segment faces torsional shearing forces at its ends. These forces are quantitatively described by the product of the longitudinal shearing stress on the segment's minor surface and the area of this surface, leading to the concept of shear flow. This shear flow is consistent throughout the structure, indicating a uniform distribution...

Area of Science:

  • Endodontic therapy
  • Dental instrument retrieval

Background:

  • Instrument separation is a common complication during endodontic procedures.
  • Thorough cleaning and shaping can be compromised by separated instruments within the root canal.

Observation:

  • Fractured instrument retrieval success depends on fragment length, canal inclination, and size.
  • Extruded fragments beyond the apex present unique retrieval challenges requiring advanced techniques and equipment.

Findings:

  • This article reviews factors influencing the outcome of extruded instrument retrieval.
  • It also focuses on various instrumental techniques specifically for retrieving files extruded beyond the root apex.

Implications:

  • Understanding these factors and techniques can improve clinical outcomes for complex endodontic cases.
  • Effective retrieval of extruded instruments is vital for preserving the tooth and ensuring successful endodontic treatment.
