Refractory apical periodontitis associated with a calculus-like deposit at the root apex
In this case report, we describe a refractory case in which a calculus-like deposit was found at the apical root surfaces of two adjacent teeth. This case involved a 45-year-old male with a sinus tract at the labial mucosa of the maxillary left central ...

Traumatic impact loading on human maxillary incisor: A Dynamic finite element analysis
Background: The most vulnerable tooth is the maxillary incisor, which sustains 80% of dental injuries. Dynamic Finite element analysis is used to understand the biomechanics of fracture of maxillary incisor under traumatic impact loading.

Polyaspartic acid‐calcium‐lanthanum (PAsp‐Ca‐La) complexes could induce antibacterial remineralization of demineralized dentin and in‐depth occlusion of dentinal tubules (DTs) with lanthanum‐doped hydroxyapatite (La‐HAp) via polyelectrolyte‐cation complexes pre‐precursor (PCCP) process, allowing the release of La3+ in response to acids generated by ...

Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?
Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...

Morphological diversity of saber‐tooth upper canines and its functional implications
Abstract Elongated upper canine teeth, commonly known as saber‐teeth, have evolved three times within the sub‐order Feliformia. The species that wielded them flourished throughout the Cenozoic and have historically been separated into two morphological groups: the dirk‐tooths with longer, flatter canines, and the scimitar‐tooths with shorter, serrated ...
