Reduction of Micro‐Motion at the Tapered Connection of Hip Endoprostheses with an Adapted Deep Rolling Process of CoCrMo Inner Tapers

Advanced Materials Interfaces, Volume 12, Issue 18, September 22, 2025.
The ball burnishing processes demonstrated a notable reduction of surface roughness, which in turn helps to reduce the formation of wear particles and is reflected in the significantly reduced wear rate. The torsional resistance in the range of micro‐motion (≈2 Nm) can be improved by implementing a ball burnishing process with augmented depth hardness.

Predictive Approaches for 3D‐Printing: Methods and Approaches for Polymeric Materials

WIREs Computational Molecular Science, Volume 15, Issue 5, September/October 2025.
3D printing shows great promise, but suffers from a restricted range of materials. We show how computational methods, from physics‐based to data‐driven methods, can streamline the development of new polymer materials. Developing integrated approaches offers future opportunities in autonomous discovery and design, harnessing 3D printing's full potential.

Assessing the Impact of Vegan Toothpastes on Enamel Color Change and Surface Properties

Journal of Esthetic and Restorative Dentistry, Volume 37, Issue 9, Page 2104-2115, September 2025.
ABSTRACT Objective To evaluate color (ΔE00) and whiteness index (ΔWID) changes, surface hardness loss (SHL), roughness (Ra), mineral content, and morphology of enamel brushed with vegan toothpastes. Methods Enamel blocks (n = 10/group) were stained with black tea (T0) underwent 15.000 (T1) and 30.000 (T2) toothbrushing cycles with: (n = 10): (AS ...

Influence of Thickener and Mineral Supplementation of Bleaching Gels on Enamel Demineralization

Journal of Esthetic and Restorative Dentistry, Volume 37, Issue 9, Page 2144-2153, September 2025.
ABSTRACT Objective This study evaluated the effect of the type of thickener and mineral supplementation of bleaching gels on enamel demineralization. Materials and Methods Enamel specimens were divided into five groups according to the type of thickener: CA‐Carbopol, AE‐Aerosil 200, PO‐Poloxamer 407, GG‐Guar gum, and HEC‐Hydroxyethyl cellulose.
