Stress in Immature Incisor Treated With Regenerative Endodontics or Restored With Bulk‐Fill Resin Composite: A 2D Finite Element Analysis

Australian Endodontic Journal, Volume 51, Issue 3, Page 660-667, December 2025.
ABSTRACT This study investigated the stress distribution on teeth undergoing regenerative endodontic treatment (RET) using two‐dimensional finite element analysis (2D FEA). Five 2D‐FEA models of immature incisors were developed, involving immediately after RET, models after RET varying root length and thickness: 10% increase in root length and root ...

Crack Propagation in Tooth Root: A Comparison Between Pulsator Test and Running Gears

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 12, Page 5181-5194, December 2025.
ABSTRACT Tooth root fatigue fracture is a critical gear failure mode in which the tooth root breaks because of the repetition of bending load. The most widely adopted procedure for evaluating root strength is through pulsator testing. However, this test method does not present gears in meshing conditions. When focusing on the limited‐life region of the

Robust and Efficient FFT‐Based Solvers for Unit‐Cell Problems With Voids and Pores Under Displacement Boundary Conditions

International Journal for Numerical Methods in Engineering, Volume 126, Issue 18, 30 September 2025.
ABSTRACT There is a variety of microstructured materials that involve voids and pores, for example, high‐porosity foams, mechanical metamaterials, or composites involving defects due to damage and cracking, respectively. Computational methods based on the fast Fourier transform (FFT) typically face convergence problems for such microstructures unless ...
