Effect of Different Airborne‐Particle Abrasion Strategies on Dentin Bond Strength: An In Vitro Study

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To assess the influence of dentin airborne‐particle abrasion techniques on the microtensile bond strength, using two adhesive strategies (self‐etch and etch&rinse). Materials and Methods Twenty molars were assigned to two groups (n = 10) according to the bonding system (Clearfil SE Bond or Optibond FL), divided into four parts and ...

Effects of gastric acid on surface roughness, microhardness, fracture strength, and color change of dental ceramics: A systematic review of in vitro studies

Journal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review evaluated the effects of simulated gastric acid (SGA) on surface and mechanical properties of dental ceramics to answer the research question: Does immersion in SGA alter the surface roughness, microhardness, fracture strength, and color of dental ceramics?

European Identity and the Euro in Kosovo

Nations and Nationalism, EarlyView.
ABSTRACT How can nationalist leaders stand for political independence and monetary sovereignty while embracing the use of a supra‐national currency? At first sight, unilateral euroisation—the de facto adoption of the euro instead of a national currency—seems inconsistent with the goals of nationalism and independence.

Laser Metal Deposited Ti4822 Hollow Pipe: Experimental and Computational Modelling Study

Advanced Engineering Materials, Volume 28, Issue 3, 4 February 2026.
Laser metal deposition (LMD) of a crack‐free built Ti4822 alloys is challenging. This article reports outstanding characteristics of a hollow pipe that is built with LMD technology when a predicted, nontransformation substrate temperature of 800 °C is used.
