Root and Canal Morphology of Maxillary Premolars in a Namibian Population: A Retrospective Cone‐Beam Computed Tomography Study

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This study examined population‐specific morphological variations in human premolar roots and canals and their clinical implications. Cone‐beam computed tomography (CBCT) was used with the Ahmed classification system. A retrospective descriptive cross‐sectional study analysed 388 maxillary premolars from CBCT scans of 97 participants obtained ...

Is Cone‐Beam CT Reliable for Apical Foramen Assessment? A Micro‐CT–Referenced Study

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the diagnostic accuracy of two cone‐beam CT (CBCT) dose protocols for identifying the number and trajectory deviation of apical foramina. Forty lower molars were scanned in Micro‐CT. Thereafter, all teeth were inserted into the mandible sockets and a titanium implant and an endodontically treated tooth with a cobalt ...

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

open access: yesActa Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.

Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...
