A description of dental microanatomy and implantation geometry in Chamaeleonidae

open access: yesJournal of Anatomy, EarlyView.
A reassessment of the dental histology in adult chamaeleons reveals the presence of periodontal ligament. Alongside alveolar bone and cementum, these tissues together constitute a compacted and remodelled tripartite periodontium. Our findings include the novel observation of plicidentine‐like protuberances of dentine within underlying bone.

The mechanism of eutectic growth in highly anisotropic materials

open access: yesNature Communications, 2016
The origins of non-periodic growth features observed in irregular eutectics have been a source of controversy. Here authors use time-resolved X-ray microtomography during eutectic growth of an alloy to show how competing models can be extended and ...

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.

Effects of Dual Wavelength Photobiomodulation on Osseointegration in Grafted Areas

open access: yesLasers in Surgery and Medicine, Volume 58, Issue 5, Page 429-436, July 2026.
ABSTRACT Objective This study evaluated the effects of dual‐wavelength photobiomodulation (PBMT) (infrared and red laser) on osseointegration and bone structure in areas grafted with deproteinized bovine bone (DBB). Methods Sixty‐four rats were randomly distributed into four groups. The groups were divided according to the irradiation protocol applied:

Performance of the Direct Current Electric Potential Difference (DCEPD) Method for Crack Extension Measurement in Fracture Mechanics Specimens Exhibiting Split Delaminations

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 7, Page 2963-2980, July 2026.
ABSTRACT This work investigates the performance of the direct current electric potential difference (DCEPD) method for measuring crack extension ( ∆a) during fracture toughness tests of ductile steels exhibiting delaminations perpendicular to the main crack plane, known as splits.

Investigating microarchitectural characteristics of woven bone exposed to ionizing radiation: comparative analysis of two segmentation methods and their impact on trabecular measurements in an animal study

open access: yesBioscience Journal
The study aimed to evaluate bone formation in surgical defects exposed to ionizing radiation (IR) and to compare two image segmentation methods: manual and standardized delimitation of the region-of-interest (ROI). Bone defects were created in the tibias
