The main components which form the enamel organ are:

*'''Outer epithelium'''

Line 29: Line 30:

The '''lamina dura''' is seen as a white line radiographically.

+

===Enamel===

+

Enamel has an '''ectodermal''' origin. It is synthesised by [[Ameloblasts|ameloblasts]]. It is very hard, densly calcified and '''acellular''', therefore cannot regenerate.

+

Complicated enamel folding occurs in teeth where the '''[[Enamel Organ#Crown|crowns]]''' are high. Enamel forming secretions pass through processes of apical cytoplasmic extension called '''Thomes' Fibres'''.
