what cells is the pulp formed from?
central cells of the dental papilla (MESODERM)
why is the pulp said to be functional by association?
because they make everything else work
how is the pulp involved in the formation of dentin?
because the odontoblasts live in th outer layer of the pulp
how does the pulp have a sensory function?
nerve cell bodies are located in the outer layers of the pulp
how does the pulp provide a nutritional function for the dentin?
passes it through the dentinal tubules
how does the pulp have a protective function?
because secondary dentin is formed from the odontoblasts in the outer layer of the pulp
what is the mass of pulp in the middle that follows the shape of the tooth called?
pulp chamber
t/f the pulp chamber follows the shape of the tooth
True
False
true
what is the pulp in the crown area called?
coronal pulp
what are the smaller extensions of coronal pulp into the crown called?
pulp horns
what are pulp horns
small extensions of coronal pulp into the crown
what is the pulp in the root areas?
radicular pulp
where is the radicular pulp located?
root areas
what type of pulp has an opening throught the dentin and cementum, out to the surrounding periodontal ligament
radicular pulp
what is the opening of the pulp into the periodontal ligament called?
apical foramen
where is the apical foramen located?
apex of the tooth
what does the apical foramen allow?
arteries, veins, lymphatics and nerves enter the tooth
what are extra openings from the pulp to the periodontal ligament?
accessory canals
what direction do accessory canals usually run?
permendicular to the root of the tooth
why do accessory canals form?
because HERS ran into a blood vessel while it was forming so it just formed a little canal around the vessel
what part of the pulp makes endo hard?
presence of accessory canals
what type of tissue is the pulp?
connective tissue
what is the pulp mainly full of because it is a connective tissue
fibroblasts
t/f the pulp has white blood cells
True
False
true
t/f the pulp contains elastic fibers and is avascular
both false-contains collagen fibers and an extensive vascular supply
what are calcified masses of dentin inside the pulp chamber
pulp stones
what is inflammation of the pulp called?
pulpitis
what are three causes of pulpitis?
extensive caries
cavity preparation
traumatic injury
what is the most common cause of pulpitis?
extensive caries
the ______ from the inflammation can cause _____ _____
pressure
severe pain
how can the pressure be relieved?
incisions and drainage or fistula
exit through apical foramen
what is a fistula?
channel that forms in the bone or soft tissue to drain infection
what happens if the inflammation exits the apical foramen
creates an abscess
what kind of treatment is done for pulpitis?
root canal therapy
what must be done after a root canal to preserve the tooth?
crown
why don't anterior teeth always need crowns after a root canal?
they don't have as high of occlusal forces
what is the canal filled with during a root canal?
gutta percha
where does gutta percha come from?
gutta percha tree
without the _____ the tooth becomes _____ and is more prone to break
