The process of dentin maturation takes place in how many phases |
2
|
|
|
What are the two phases of maturation of dentin |
Primary Secondary |
|
|
Initially the calcium hydroxyapatite crystals form as what? |
Globules or calcospherules in the collagen fibers of the predentin which allows for both expansion and fusion during the primary mineralization phase |
|
|
Later, what happens? |
New areas of mineralization occur as globules in the form partially mineralized predentin during the secondary mineralization stage |
|
|
The first stage what basically happens? |
Globules bleed together |
|
|
The second stage what basically happens? |
is a globular layer of dentin that does not "bleed" or blend together. It's incompletely fused together forming a slightly more distinct pattern than in the first mineralization |
|
|
Globular dentin is considered what? |
Areas where both primary and secondary mineralization has occurred with complete crystalline fusion |
|
|
So where is globular dentin seen? |
where primary and secondary mineralization has occurred |
|
|
How do globular dentin appear |
Lighter rounded areas on a stained section of dentin |
|
|
Interglobular dentin is seen where? |
Only where primary mineralization has occurred and the globules do not fuse together completely |
|
|
Which is less mineralized interglobular or globular dentin? |
Interglobular Dentin |
|
|
Where is interglobular dentin especially evident |
Coronal dentin near the DEJ certain dental anomalies such as in (dentin dysplasia) |
|
|
Interglobular dentin appears how? |
darker arclike areas in a stained section of dentin |
