|
______ epithelium induces odontoblast formation
______ and ______ induce enamel formation |
Enamel; Dentin; Odontoblasts
|
|
|
What is involved in the formation of dentin
|
the pulp
|
|
|
what kind of matrix does the pulp synthesize and release?
|
inorganic
|
|
|
What is primary Dentin?
|
Dentin formed prior to the root end completion. Primary Dentinogenesis is a relatively rapid process and is carried out by primary odontoblasts
|
|
|
Secondary Dentin?
|
After root end completion; slower process that continues over life of tooth.
|
|
|
What dentin is formed in response to injury or irritation?
|
tertiary dentin
|
|
|
What dentin is formed in response to MILD irritation and is continuous with secondary dentin
|
Reactive dentin
|
|
|
What makes reactive dentin?
|
primary odontoblasts; like primary and secondary dentin
|
|
|
How is reparative dentin different?
|
more severe injury; atubular and poorly organized; not continuous with 2ndary dentin; formed by cells after primary odontoblast have died
|
|
|
pulp nutrition is through its own circulatory system
|
that is all
|
|
|
odontoblasts respond to caries/injury by laying down dentin....what happens(think dentin) if a pulp exposure occurs?
|
dentin is formed through the induction differentiation and migration of stem cells to the exposure site.
|
|
|
does the pulp ever elicit an immune response?
|
yes, it can identify and process foreign substances
|
|
|
T or F
While the nerves in the pulp can respond to stimuli applied directly to the tissue, the pulp has no proprioreception. |
T
|
|
|
T or F
Pulps can tell both themal changes and pain |
F,
Pulp can only interpret pain usually through fast and sharp |
|
|
__ ________ fibers are the sharp pain. _______ __ fibers are the deep dull ache
|
Ad myelinated;
non myelinated C |
