The Anatomical Record, EarlyView.Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Material properties of periodontal ligaments
Postępy Higieny i Medycyny Doświadczalnej, 2013 The mechanism of orthodontic teeth movement is not entirely explained. The principal reaction on tissues at the cellular and molecular level is initiated by the force applied to the tooth crown and transferred in turn upon the periodontal ligament (PDL).

BMEMat, EarlyView.Extracellular vesicles (EVs) derived from stem cells show promise for applications in regenerative medicine, but their scalability and yield remain challenges. This review explores the approaches for biophysical modulations within cell niches on EV properties, discusses the current clinical application of EVs, and provides an outlook on the existing ...

Possible Involvement of Leptin in Pathogenesis of Periodontal Disease
BiologyPeriodontitis is a chronic inflammatory condition of the periodontal tissues, ultimately leading to their destruction. The periodontal ligament is a key structure that not only secures the teeth within the alveolus but can also act as a source of ...

Non uniformity: structural strategy for optimizing functionality in skeletal ligaments [PDF]
, 2017 Ligaments serve as compliant connectors between hard tissues. In that role, they function under various load regimes and directions. However, the 3D structure of ligaments is still considered uniform.

Exosome as bioactive nanovesicle for diagnostic and therapeutic applications in periodontitis
BMEMat, EarlyView.This review introduces the mechanism that exosomes participate in the pathogenesis of periodontitis and their potential as biomarkers for early diagnosis and summarizes the application of cell‐ or plant‐derived exosomes or engineered exosomes in periodontitis or periodontal regeneration while proposing the perspective of translational application of ...
