Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

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

open access: yesMicroscopy 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.

Evaluating the Air Respiratory Capacity of Awaous (Chonophorus) tajasica (Gobiiformes: Oxudercidae): A Morpho‐Functional Study

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
We demonstrated that Awaous tajasica performs facultative air breathing under experimental conditions of dissolved oxygen limitation, retaining air bubbles in the buccal cavity during gill ventilation. Morpho‐functional evidence indicates the use of atmospheric oxygen as a respiratory support under conditions of low water oxygenation.

Cost‐effectiveness and long‐term outcomes of periodontal regeneration versus dental implants: A retrospective study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Direct comparative data on periodontal regeneration (PR) versus extraction and implant placement remain limited. Tooth‐specific periodontal conditions such as furcation involvement and overall tooth prognosis may dictate success or failure of such treatment.
