can any restorative procedure affect the pulp?
YES
what are the effects of irritants and restorative procedures on the pulp
- affect pulp thru dentinal tubule (indirect)
- can produce damage thru pulp exposure (direct)
- can generate heat that affects pulp

what encompasses the treatment of diseases and injuries to the pulp and associated periradicular tissues
endodontics
what is the AAE
american association of endodontics
what is located in the center of crown and root and is made of loose connective tissues
dental pulp
what is enclosed in hard walls (dentin)
dental pulp
what has poor collateral circulation and is terminal end circulation
dental pulp
when the dental pulp is removed intact, does it maintain its shape
yes, it is a firm tissue that remains its shape
what holds the connective tissue of the dental pulp? what reinforces this structure?
held together by ground substance; reinforced by collagen fibers
what is the derivative of dental pulp
neural crest cells/ectomesenchyme
proliferation and condensation of neural crest/ectomesenchyme forms what
dental papilla
what is the mature pulp derived from
dental papilla
what is enamel derived from
enamel organ
what is pulp and dentin derived from
dental papilla
what is cementum and PDL derived from
dental sac
what is step 1 of tooth development
papilla -> IEE -> ameloblasts
what is step 2 of tooth development
ameolblasts -> papilla -> odontoblasts -> predentin
what is step 3 of tooth development
predentin -> ameloblasts -> enamel
what is the epithelial diaphragm also called
cervical loop
the epithelial diaphragm is the junction of what
IEE and OEE
the epithelial diaphragm is the future what
CEJ
the proliferation of what forms the root
HERS
what happens when HERS is ruptured
exposes dentin to connective tissue. exposed dentin stimulates cementum deposition
what are epithelial remnants from HERS and remain dormant
Cell Rests of Malasseze
if cell rests of Malasseze are activated by inflammation, what happens
can proliferate providing lining of radicular cysts
