Downregulation of FGF Signaling by Spry4 Overexpression Leads to Shape Impairment, Enamel Irregularities, and Delayed Signaling Center Formation in the Mouse Molar. [PDF]

open access: yes, 2019
FGF signaling plays a critical role in tooth development, and mutations in modulators of this pathway produce a number of striking phenotypes. However, many aspects of the role of the FGF pathway in regulating the morphological features and the mineral ...

Orthodontic management of dentition in patients with periodontally compromised dentition

open access: yesJournal of Indian Society of Periodontology, 2014
An increasing number of adult patients are seeking orthodontic treatment to improve their dental appearance. However, special attention must be given to the periodontal status of the adults as periodontal disease and its sequel, such as pathologic migration of anterior teeth, result in esthetic and functional problems.

Supervariate Gel Transforms into Various Biominerals in Salt Solutions

open access: yesAdvanced Functional Materials, EarlyView.
It is revealed that common calcium‐based biominerals can form from a stable, non‐toxic ‘supervariate’ gel. This tunable gel selectively yields calcite or hydroxyapatite in carbonate/phosphate solutions, while CaCl₂ facilitates the formation of dihydrate calcium pyrophosphate, which converts to hydroxyapatite upon drying. These findings provide insights

Genetic and environmental determinants of dental occlusal variation in South Australian twins

open access: yesAustralasian Orthodontic Journal, 1998
As part of an ongoing study of dentofacial morphology in South Australian twins, several occlusal traits were compared between forty eight monozygous and thirty four dizygous twin pairs, as well as estimating genetic variances for these features ...

Localisation of the unerupted maxillary canine: further observations

open access: yesAustralasian Orthodontic Journal, 1998
This paper discusses the interpretation of radiographs taken to localise impacted maxillary canines. In particular, the sometimes unexpected radiographic appearance of labially impacted canines is explained.

Controlled Release of Human Dental Pulp Stem Cell‐Derived Exosomes from Hydrogels Attenuates Temporomandibular Joint Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
Exosomes can reduce tissue damage in temporomandibular joint osteoarthritis (TMJOA), but rapid clearance limits their efficacy. This study encapsulates exosomes in hyaluronic acid hydrogels for controlled release. In a rat model, hydrogel‐encapsulated exosomes outperform free exosomes in preserving bone integrity and reducing tissue destruction ...

Pulmonary Delivery of siRNA Anti‐TNFα‐loaded Lipid Nanoparticles for Rapid Recovery in Murine Acute Lung Injury

open access: yesAdvanced Healthcare Materials, EarlyView.
In a murine model of acute lung injury, pulmonary administration of lipid nanoparticles carrying TNFα siRNA enables targeted delivery to immune cells. The study emphasises the importance of optimizing LNP distribution and delivery timing to improve therapeutic outcomes and develop emergency therapies for lung hyperinflammation.

Plesippus francescana (Frick) from the late Pliocene, Coso Mountains, California, with a review of the genus Plesippus [PDF]

open access: yes, 1936
Two mammalian types, occurring in a late Pliocene fauna from the Coso Mountains, California, have already been described. Among the more abundant forms in this assemblage are the horses of the genus Plesippus.

A Model for the Analysis of Caries Occurrence in Primary Molar Tooth Surfaces [PDF]

open access: yes, 2012
Recently methods of caries quantification in the primary dentition have moved away from summary ‘whole mouth’ measures at the individual level to methods based on generalised linear modelling (GLM) approaches or survival analysis approaches. However, GLM
