Nrf2 deficiency causes tooth decolourization due to iron transport disorder in enamel organ [PDF]
, 2004 Rodents have brownish-yellow incisors whose colour represents their iron content. Iron is deposited into the mature enamel by ameloblasts that outline enamel surface of the teeth.

International Journal of Surgery Case Reports, 2014 Ameloblastic fibro-odontoma (AFO) is a quite rare, mixed odontogenic tumour generally seen in the early stages of life. Frequent signs of this tumour are asymptomatic swelling, delayed tooth eruption and mixed radiological appearance within well-defined borders.

Amelogenesis Imperfecta caused by N-Terminal Enamelin Point Mutations in Mice and Men is driven by Endoplasmic Reticulum Stress [PDF]
, 2017 ‘Amelogenesis imperfecta’ (AI) describes a group of inherited diseases of dental enamel that have major clinical impact. Here, we identify the aetiology driving AI in mice carrying a p.S55I mutation in enamelin; one of the most commonly mutated proteins ...

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 ...

Comparison of Two Mouse Ameloblast-like Cell Lines for Enamel-specific Gene Expression
Frontiers in Physiology, 2014 Ameloblasts are ectoderm-derived cells that produce an extracellular enamel matrix that mineralizes to form enamel. The development and use of immortalized cell lines, with a stable phenotype, is an important contribution to biological studies as it ...
