It originates from pluripotential cephalic neural crest cells which subsequently migrate towards the first pharyngeal arch, there to trigger (in combination with mesodermal cells) the development of many elements of the craniofacial structures [4–6][4][5][6].
Enamel formation is called amelogenesis and occurs in the crown stage (advanced bell stage) of tooth development. "Reciprocal induction" governs the relationship between the formation of dentin and enamel; dentin formation must always occur before enamel formation. Generally, enamel formation occurs in two stages: the secretory and maturation stages. Proteins and an organic matrix form a partially mineralized enamel in the secretory stage; the maturation stage c…
