Digital Dental Radiology and Diagnostics—From 2D to 3D

open access: yesAustralian Dental Journal, EarlyView.
ABSTRACT Digital dental radiology has evolved significantly from traditional two‐dimensional (2D) imaging to advanced three‐dimensional (3D) modalities such as cone‐beam computed tomography (CBCT). This progression has overcome many limitations of 2D imaging, including superimposition and distortion, enabling more accurate visualisation of complex ...

Effects of Access Cavity Design on the Shaping Ability and Dentine Thickness Following Canal Preparation Using XP‐Endo Shaper or Reciproc

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This study compared the shaping ability and remaining dentine thickness in mandibular molars prepared with traditional (TradAC) or ultraconservative (UltraAC) access cavities using Reciproc or XP‐endo Shaper instruments. Thirty‐two molars were scanned with micro‐CT before and after preparation to assess canal surface, volume, untouched walls ...

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.
