The enamelin and the ameloblast in function as nucleators, attracting ions to their protein structure to favor the organized deposit of crystals of calcium phosphate salts.
There are many variants of ameloblastomas, but the cell type tends to mimic the ameloblast.
quantitative defect (deficient enamel ma- trix formation) due to disruption of the secre- tory phase during ameloblast function.
Monophasic pattern comprises only of clear cell while ameloblastomatous pattern, (6) resembles the growth pattern of ameloblast with nest of cell showing cystic changes and squamous differentiation and peripheral nuclear pallisading with reverse polarity.
If the ameloblasts are interrupted during either of these stages, enamel will be either anomalously thin or, in some severe cases where the ameloblast cells die, completely absent.
2009) Ctip2/Bcl11b controls ameloblast formation during mammalian odontogenesis.
INTRODUCTION Ameloblastoma is a tumour of odontogenic epithelial origin and is composed of ameloblast like cells1.
Amelogenin interacts with cytokeratin 5 in ameloblast during enamel growth.
Enamel consists of hydroxyapatite crystallites secreted by ameloblast cells, and crystallites can be nonprismatic, as in most reptiles, or arranged into prisms and interprismatic material, as in most mammals (Koenigswald, 1982; Sahni, 1985).
9,10) The undulating course of ameloblast during amelogenesis results in the formation of a specific pattern by so, the course of enamel rods is not the same throughout the thickness of enamel.
When this complex sequence of cytological and physico-chemical events is disrupted by genetic or environmental factors the function of the ameloblast may be disrupted perma- nently or temporarily.
