Synergistic Functions Of Gli2 And Gli3 In Tooth Root Morphogenesis.

open access: yesInternational Dental Journal
Aim or purpose: Hedgehog signaling pathway has been implicated as a pivotal transduction center in orchestrating tooth morphogenesis. Gli2 and Gli3, downstream transcriptional factors of Hedgehog signaling, exhibit synergistic functions in directing ...

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

open access: yesThe Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

A Summary of the Research on the Effect of Gear Tooth Root Strengthening on Bending Fatigue Strength based on Residual Stress

open access: yesJixie chuandong, 2019
With the continuous development of engineering technology, bending fatiguestrength has become an important limiting factor for the further development of gears, and bending fatigue failure is more dangerous than tooth surface failure.

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs

open access: yesThe Anatomical Record, EarlyView.
Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...

Mathematical Model for Analysis of Translational Displacements of Tooth Root

open access: yes, 2015
Analytical modeling of stress-strain state of a periodontal ligament in the case of the translational displacement of a tooth root was carried out. The tooth root was assumed as a rigid body.

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

THE DETERMINNATION OF RESIDUAL STRESS OF GEAR TOOTH ROOT BASED ON X-RAY TECHNOLOGY

open access: yesJixie qiangdu, 2017
Transverse residual stress of tooth root has significant influence on bending fatigue strength of gears.But given the geometry of gears,using the method of exposing teeth root to complete determination of transverse residual stress at present,it not only
