Effects of Early-Life Adversity on Tooth Enamel Formation

Frontiers in Dental Medicine, 2022
In a systemic effort to survive environmental stress, organ systems fluctuate and adapt to overcome external pressures. The evolutionary drive back toward homeostasis makes it difficult to determine if an organism experienced a toxic exposure to stress ...

Sodium-Calcium Exchangers in Rat Ameloblasts

Journal of Pharmacological Sciences, 2010
Although the central role of ameloblasts in synthesis and resorption of enamel matrix proteins during amelogenesis is well documented, the Ca2+-transport/extrusion mechanism remains to be fully elucidated. To clarify Ca2+-transport in rat ameloblasts, we

ADAM10: Possible functions in enamel development

Frontiers in Physiology, 2022
ADAM10 is A Disintegrin And Metalloproteinase (ADAM) family member that is membrane bound with its catalytic domain present on the cell surface. It is a sheddase that cleaves anchored cell surface proteins to shed them from the cell surface.

Modeling ameloblast-matrix interactions using 3D cell culture

Frontiers in Physiology, 2022
The distinct morphology adopted by ameloblasts during amelogenesis is highly stage specific and involved intimately with the development of a hierarchical enamel microstructure.

Ameloblastic fibro-odontoma [PDF]

BMJ Case Reports, 2015
Ameloblastic fibro-odontoma is a slow growing, benign, expansile epithelial odontogenic tumour with odontogenic mesenchyme, accounting for 0.3–1.7% of jaw tumours, signifying its rarity. The WHO defines it as “a neoplasm composed of proliferating odontogenic epithelium in a cellular ectomesenchymal tissue with varying degrees of inductive changes and ...

Estrogen-deficiency Effect on the Composition of Dental Enamel: A Pilot Study

Scientific Dental Journal, 2021
Background: Tooth enamel mineralization is assumed to be a target of endogenous estrogen imbalances. Objective: To evaluate the effect of estrogen deficiency during amelogenesis on the mineral composition of dental enamel.

Ameloblastic fibroma, ameloblastic fibro-odontoma, and odontoma

Oral and Maxillofacial Surgery Clinics of North America, 2004
Ameloblastic fibroma (AF) is a relatively rare true tigators believe that AF and AFO are variations of the mixed tumor in which epithelial and the ectomesenchymal elements are neoplastic. It is characterized by the simultaneous neoplastic proliferation of the mesenchymal and epithelial components without formation of dental hard tissues, namely dentin ...

Towards unraveling the human tooth transcriptome: the dentome. [PDF]

PLoS ONE, 2015
The goal of the study was to characterize the transcriptome profiles of human ameloblasts and odontoblasts, evaluate molecular pathways and advance our knowledge of the human "dentome".

Stem cells for tooth engineering [PDF]

European Cells & Materials, 2008
Tooth development results from sequential and reciprocal interactions between the oral epithelium and the underlying neural crest-derived mesenchyme. The generation of dental structures and/or entire teeth in the laboratory depends upon the manipulation ...

Targeted overexpression of amelotin disrupts the microstructure of dental enamel. [PDF]

PLoS ONE, 2012
We have previously identified amelotin (AMTN) as a novel protein expressed predominantly during the late stages of dental enamel formation, but its role during amelogenesis remains to be determined. In this study we generated transgenic mice that produce
