Macroscopic, Histological and Ultrastructural Features of the Tongue of the Anatolian Wild Boar (Sus scrofa libycus)

Microscopy Research and Technique, EarlyView.
Integrated macroscopic, histological, and ultrastructural analyses revealed five distinct lingual papillae types (filiform, fungiform, conical, foliate, and vallate) in the Anatolian wild boar (Sus scrofa libycus). Mechanical papillae showed marked structural specialization, while gustatory papillae exhibited region‐specific distribution of taste buds.

Deep learning cone‐beam computed tomography image segmentation for the 3D visualization of mandibular infraosseous periodontal defects

Journal of Periodontology, EarlyView.
Abstract Background The accurate assessment of infraosseous periodontal defects is crucial for effective diagnosis and treatment planning. Cone‐beam computed tomography (CBCT) enables detailed imaging of these defects; however, to leverage their full potential, CBCT images must be reconstructed in 3 dimensions (3D).
