Molar incisor hypomineralisation: current knowledge and practice

open access: yesInternational 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

open access: yesFrontiers 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.

Ameloblastic fibroma

open access: yesJournal of Oral and Maxillofacial Pathology, 2012
Ameloblastic fibroma is a rare odontogenic tumor comprising neoplastic epithelial and mesenchymal tissues. This lesion was previously considered to be a benign lesion with very limited recurrence rate and malignant transformation. However, recent reports have suggested that this lesion has the potential for recurrence and malignant transformation.

Ameloblastic fibrodentinosarcoma and ameloblastic fibro-odontosarcoma: A systematic review [PDF]

open access: yesJournal of Stomatology, Oral and Maxillofacial Surgery, 2018
The purpose of the present review was to integrate the available data published on ameloblastic fibrodentinosarcoma (AFDS) and ameloblastic fibro-odontosarcoma (AFOS) into a comprehensive analysis of their clinical/radiologic features. An electronic search was undertaken in July/2017.

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

open access: yesPLoS 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 ...

Overexpression of RCAN1, a Gene on Human Chromosome 21, Alters Cell Redox and Mitochondrial Function in Enamel Cells

open access: yesCells, 2022
The regulator of calcineurin (RCAN1) has been implicated in the pathogenesis of Down syndrome (DS). Individuals with DS show dental abnormalities for unknown reasons, and RCAN1 levels have been found to be elevated in several tissues of DS patients.

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

open access: yesFrontiers 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 ...

Amelogenesis Imperfecta; Genes, Proteins, and Pathways

open access: yesFrontiers 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,

Mitochondrial Function in Enamel Development

open access: yesFrontiers in Physiology, 2020
Enamel is the most calcified tissue in vertebrates. Enamel formation and mineralization is a two-step process that is mediated by ameloblast cells during their secretory and maturation stages.

Enamel Defects Associated With Dentin Sialophosphoprotein Mutation in Mice

open access: yesFrontiers in Physiology, 2021
Dentin sialophosphoprotein (DSPP) is an extracellular matrix protein that is highly expressed in odontoblasts, but only transiently expressed in presecretory ameloblasts during tooth development. We previously generated a knockin mouse model expressing a
