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
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.

formation during mammalian odontogenesis.
INTRODUCTION Ameloblastoma is a tumour of odontogenic epithelial origin and is composed of ameloblast
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.
14) Their molars' crown morphology is deformed, with additional cusps, and their incisors ameloblast
cytodifferentiation is inhibited as well as enamel matrix deposition.
