Translucency Changes of Ceramic Veneers After Aging When Cemented on Substrates With Different Saturation: Effect of Ceramic Translucency and Resin Cement Shade

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of ceramic translucency and resin cement shade on the translucency alteration after aging over different substrates. Methods Sixty specimens were divided into 12 groups (n = 5) composed of lithium disilicate (IPS e.max CAD, Ivoclar Vivadent) in three translucencies (HT, MT, LT).

Influence of Illumination Conditions and Cross‐Polarization on DSLR‐Based Clinical Tooth Color Assessment: A Comparison With Spectrophotometric Measurements

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Aim To evaluate the influence of different illumination systems and cross‐polarization on tooth color determination using DSLR photography, and to assess the agreement between photographic methods and spectrophotometric measurements. Materials and Methods Thirty‐one participants (62 maxillary central incisors) were included. Color measurements

A Bayesian approach to spectroscopic depth sectioning for locating dopant atoms

Journal of Microscopy, EarlyView.
Abstract Locating dopants in 3D is of great interest as advanced materials and devices increasingly rely on control at atomic dimensions, and microscopy tools are constantly in development for this purpose. One potential tool is electron energy loss spectroscopy (EELS) depth sectioning, where a core‐loss signal is collected as a function of electron ...

Hyperspectral tomographic diffractive microscopy: Development and applications

Journal of Microscopy, EarlyView.
Abstract Tomographic Diffractive Microscopy (TDM) provides label‐free three‐dimensional imaging of transparent samples with resolution surpassing confocal limits. At IRIMAS, successive instrumental developments since 2009 have enhanced TDM capabilities through transmission, reflection, isotropic, polarisation‐sensitive, and dual‐view configurations ...

The Origins of Ploem's Filter Cube: A Pandora's Box

Journal of Microscopy, EarlyView.
Abstract Ploem's filter cube, central to modern epifluorescence microscopy, integrates three matched optical components: an excitation filter, an emission filter, and a dichroic mirror. Together, these elements enable the separation of excitation and emission light paths, producing high‐contrast fluorescence images.

SynapTrack: An automated tool for synapse quantification

Journal of Microscopy, EarlyView.
Abstract Reliable synapse quantification remains challenging, particularly in high‐throughput fluorescence imaging workflows. Here we present SynapTrack, a fully automated FIJI/ImageJ‐based tool for quantifying synapses in cultured neurons and brain tissue sections with minimal user intervention.
