Odontogenic ameloblast-associated (ODAM) is inactivated in toothless/enamelless placental mammals and toothed whales

BMC Evolutionary Biology, 2019
The gene for odontogenic ameloblast-associated (ODAM) is a member of the secretory calcium-binding phosphoprotein gene family. ODAM is primarily expressed in dental tissues including the enamel organ and the junctional epithelium, and may also have ...

Fabrication of functional ameloblasts from hiPSCs for dental application

Frontiers in Cell and Developmental Biology, 2023
Tooth formation relies on two types of dental cell populations, namely, the dental epithelium and dental mesenchyme, and the interactions between these cell populations are important during tooth development. Although human-induced pluripotent stem cells

SATB1 establishes ameloblast cell polarity and regulates directional amelogenin secretion for enamel formation

BMC Biology, 2019
Polarity is necessary for epithelial cells to perform distinct functions at their apical and basal surfaces. Oral epithelial cell-derived ameloblasts at secretory stage (SABs) synthesize large amounts of enamel matrix proteins (EMPs), largely amelogenins.

Stress Response Pathways in Ameloblasts: Implications for Amelogenesis and Dental Fluorosis

Cells, 2012
Human enamel development of the permanent teeth takes place during childhood and stresses encountered during this period can have lasting effects on the appearance and structural integrity of the enamel.

The resistance of succedaneous teeth to periapical infection: A series of seven cases

Contemporary Clinical Dentistry, 2021
Pediatric dental procedures are carried out largely to prevent the adverse effects of primary teeth infection on succedaneous teeth (ST). The existing literature on how and when periapical infection (PI) from primary teeth affect ST is conflicted.

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 ...

From Pluripotent Stem Cells to Organoids and Bioprinting: Recent Advances in Dental Epithelium and Ameloblast Models to Study Tooth Biology and Regeneration

Stem Cell Reviews and Reports
Ameloblasts are the specialized dental epithelial cell type responsible for enamel formation. Following completion of enamel development in humans, ameloblasts are lost and biological repair or regeneration of enamel is not possible.

Energy metabolic shift contributes to the phenotype modulation of maturation stage ameloblasts

Frontiers in Physiology, 2022
Maturation stage ameloblasts (M-ABs) are responsible for terminal enamel mineralization in teeth and undergo characteristic cyclic changes in both morphology and function between ruffle-ended ameloblasts (RA) and smooth-ended ameloblasts (SA).

MMP20 Overexpression Disrupts Molar Ameloblast Polarity and Migration

Journal of dentistry research, 2018
Ameloblasts responsible for enamel formation express matrix metalloproteinase 20 (MMP20), an enzyme that cleaves enamel matrix proteins, including amelogenin (AMELX) and ameloblastin (AMBN).
