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.

Mini-implant assisted rapid palatal expansion: New perspectives

open access: yes, 2017
Maxillary endognathy is a fundamental problem of the transverse dimension, which is very common during childhood. The conventional treatment for this dysmorphia is rapid maxillary expansion using a mid-palatal jack screw.

Surgically assisted rapid palatal expansion: is the pterygomaxillary disjunction necessary? A finite element study

open access: yes, 2022
© 2022 Elsevier Inc.Transverse discrepancy is an important factor in determining facial esthetics. It has been shown there is an inverse correlation between the buccal corridor width and the intercanine and intermolar widths.

Loss of Twist1 leads to disruption of ciliary length, endocytic vesicle dynamics, and cell–cell junctions during neural tube formation

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Endocytosis constitutes a fundamental cellular process governing development through coordinated regulation of plasma membrane remodeling and ciliogenesis, processes essential for cell shape changes and tissue development. Although Twist1 null embryos display complete cranial neural tube (NT) closure defects and conditional knockout

Fixed versus Removable Appliance for Palatal Expansion; A 3D Analysis Using the Finite Element Method.

open access: yesFrontiers in Dentistry, 2014
Several appliances have been used for palatal expansion for treatment of posterior cross bite. The purpose of this study was to evaluate the stress induced in the apical and crestal alveolar bone and the pattern of tooth displacement following expansion ...

Success and Failure of MSE II Assisted MARPE: Comparative Evaluation of Two Cases

open access: yesJournal of Indian Orthodontic Society
Mini-implant-assisted rapid palatal expansion (MARPE) offers a less invasive option for management of skeletal maxillary transverse discrepancy in advanced stages of palatal sutural maturation that cannot be optimally addressed by conventional rapid ...

Membrane lipid metabolism as a regulatory frontier in neural crest biology: Roles for sphingolipids, cholesterol, and lipid rafts

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Neural crest cells are multipotent, migratory stem‐like cells essential for vertebrate development that contribute broadly to many tissues including the craniofacial skeleton, peripheral nervous system, and pigment‐producing cells. Their development progresses through phases of induction, specification, delamination, migration, and ...

Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...
