Tooth-bone attachment tissue is produced by cells with a mixture of odontoblastic and osteoblastic features in reptiles. [PDF]

J Anat
Tooth attachment in vertebrates ranges from ligament‐based anchorage in mammals to direct fusion in many reptiles. In the veiled chameleon, we identified a transient cell population—termed ankyloblasts—at the tooth‐bone interface. These cells exhibit both odontoblast‐ and osteoblast‐like features.

Molar incisor hypomineralisation: current knowledge and practice

International Dental Journal, EarlyView., 2020
Background Molar incisor hypomineralisation (MIH) is a common developmental dental condition that presents in childhood. Areas of poorly formed enamel affect one or more first permanent molars and can cause opacities on the anterior teeth. MIH presents a variety of challenges for the dental team as well as functional and social impacts for affected ...

Endocytosis and Enamel Formation

Frontiers in Physiology, 2017
Enamel formation requires consecutive stages of development to achieve its characteristic extreme mineral hardness. Mineralization depends on the initial presence then removal of degraded enamel proteins from the matrix via endocytosis.

Intraspecific variation in M1 enamel development in modern humans: implications for human evolution [PDF]

, 2008
The timing and sequence of enamel development, as well as enamel thickness, was documented for individual cusps (protoconid, hypoconid,metaconid, entoconid) in 15 unworn permanent lower first molars (M1s) from a sample of modern human juveniles.

Fluoride Alters Klk4 Expression in Maturation Ameloblasts through Androgen and Progesterone Receptor Signaling

Frontiers in Physiology, 2017
Fluorosed maturation stage enamel is hypomineralized in part due to a delay in the removal of matrix proteins to inhibit final crystal growth. The delay in protein removal is likely related to reduced expression of kallikrein-related peptidase 4 (KLK4 ...

The acid test of fluoride: how pH modulates toxicity. [PDF]

PLoS ONE, 2010
It is not known why the ameloblasts responsible for dental enamel formation are uniquely sensitive to fluoride (F(-)). Herein, we present a novel theory with supporting data to show that the low pH environment of maturating stage ameloblasts enhances ...

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.

Zebrafish teeth as a model for repetitive epithelial morphogenesis: dynamics of E-cadherin expression [PDF]

, 2010
Background: The development of teeth is the result of interactions between competent mesenchyme and epithelium, both of which undergo extensive morphogenesis.

Amelogenesis Imperfecta; Genes, Proteins, and Pathways

Frontiers in Physiology, 2017
Amelogenesis imperfecta (AI) is the name given to a heterogeneous group of conditions characterized by inherited developmental enamel defects. AI enamel is abnormally thin, soft, fragile, pitted and/or badly discolored, with poor function and aesthetics,
