Spatial Abilities and Endodontic Access Cavity Preparation: Implications for Dental Education. [PDF]
Eur J Dent EducABSTRACT Introduction Access cavity preparation is a crucial step in root canal treatment but is one of the most complex procedures in the curriculum to learn, with students often reporting spatial orientation difficulties during drilling. The present study aimed to evaluate the influence of spatial abilities on the preparation of endodontic access ...

Journal of Applied Polymer Science, Volume 140, Issue 3, January 15, 2023., 2023 Abstract A strategy of CO2‐assisted extrusion foaming of PMMA‐based materials was established to minimize both foam density and porosities dimension. First a highly CO2‐philic block copolymer (MAM: PMMA‐PBA‐PMMA) was added in PMMA in order to improve CO2 saturation before foaming.

A generic topography reconstruction method based on multi‐detector backscattered electron images
Strain, Volume 58, Issue 5, October 2022., 2022 Abstract Surface topographies can be reconstructed from backscattered electron (BSE) images captured from different detector orientations. This article presents a very general approach to this problem, in the spirit of photometric stereo methods, allowing for arbitrary BSE detector number (at least 3) and shapes.
