Immunohistochemical expression of podoplanin (D2‐40), lymphangiogenesis, and neoangiogenesis in tooth germ, ameloblastomas, and ameloblastic carcinomas

Journal of Oral Pathology & Medicine, 2017
BACKGROUND Ameloblastoma is a benign but locally aggressive odontogenic tumor, while ameloblastic carcinoma is its malignant counterpart. Angiogenesis and lymphangiogenesis in malignancies have been correlated with higher aggressiveness and poor ...

Lungfish‐like antero‐labial tooth addition and amphibian‐like enameloid‐enamel transition in the coronoid of a Devonian stem actinopterygian

Journal of Anatomy, EarlyView.
The tooth patterning logic, which cannot be inferred from surface morphology, is revealed by visualizing buried tooth remnants in 3D. The primary teeth are added labially, initially organized in radial rows, which transition into linear rows where the coronoid becomes slender.

Whole Tooth Regenerative Therapy Using a Bioengineered Tooth Germ [PDF]

Current Oral Health Reports, 2013
Dental disorders, including dental caries and periodontal disease, can cause fundamental problems for oral functions, such as enunciation, mastication and occlusion, as well as general health issues. Tooth regenerative therapies for tissue repair and whole tooth replacement are currently being developed as novel treatment approaches.

Gestational protein restriction alters the RANKL/OPG system in the dental germ of offsprings

Journal of Oral Biology and Craniofacial Research, 2020
Objective: Evaluate the dentinogenesis in the offspring of rats submitted to gestational protein restriction (GPR). Design: The offspring were evaluated at the 21st day of gestation (21 dG). Assessments were made of morphological parameters and the RANKL/

Systemic, Lifestyle and Environmental Modifying Factors in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
A variety of impacting factors in the pathogenesis of periodontitis exist, including systemic, lifestyle, and environmental factors. This review highlights the manifold mechanistic aspects of the link between the pathogenesis of periodontitis, addressing these numerous factors to supplement the long‐standing knowledge of the progression of the disease.

The Influence of Cryopreservation on the Oligosaccharide Expression of Tooth Germ-Sugar Chain Expression of Frozen Tooth Germs-

Journal of Hard Tissue Biology, 2005
To explore the influence of preservation by freezing on tissues of tooth germ, we examined changes in histological architectures and glycoconjugate expression detected by lectins, in tooth germs, with or without freezing, of postnatal 5 day rats. The results acquired were as follows: tissue architectures and cellular morphologies were similar between ...

Dilated Odontoma Arising in the Mandibular Third Molar Germ: Report of a Case of an Unusual Lesion in an Uncommon Site

Diagnostics, 2021
Dilated odontoma is the most severe variant of dens invaginatus. It is extremely uncommon in the posterior mandible. It is thought to originate during the morpho-differentiation stage of dental development.

Stem Cells From Dental Pulp, Periodontal Tissues, and Other Oral Sources: Biological Concepts and Regenerative Potential

Journal of Periodontal Research, EarlyView.
A graphical abstract recapping the different sources of dental, periodontal, and other oral‐derived mesenchymal stromal cells (MSCs) and their regenerative mechanisms and potentials. The review's article findings bridge fundamental biological science with translational advances, highlighting the significance of MSCs in craniofacial regenerative ...

Nitrate Prevents Sjögren's Disease by Modulating T Helper Cells via NF‐κB Pathway Suppression

Oral Diseases, EarlyView.
ABSTRACT Objective Sjögren's disease (SjD) is a chronic autoimmune disease characterized by abnormal T helper (Th) cell distribution in the salivary glands (SGs). Although nitrate can regulate immune responses and preserve SGs function, its preventive effects on SjD remain unexplored.

Heterogeneity of amelogenin mRNA in the bovine tooth germ. [PDF]

Journal of Biological Chemistry, 1987
The amelogenins are a complex mixture of hydrophobic proteins that are the major organic component of developing enamel. To study the molecular mechanisms underlying the heterogeneity of the amelogenins we isolated cDNA clones encoding these proteins. The clones were definitively identified by hybrid-selected translation experiments and by comparison ...
