Chapter 2 Tooth Flashcards
(54 cards)
tooth functions
protection, digestion, speech, and apperance
2 main part of tooth
crown and root
cementum
thin layer covers root
dentin hardness like
a bone
pulp chamber found in
the crown
pulp canal
found in root
what is the function of cementum
main part of the tooth that helps attach it to the bone
alveolar bone surrounds
the tooth
alveolar process
hugs the tooth
pdl fibers
periodontal ligaments
connect tooth to the bone
apex
end
apical foramen
opening at the end of tooth in root
- nerves and blood supply pass through to the pulp
sulcus
shallow groove which tooth and gums meet
gingiva
gum
cusp
tip of tooth elevation
anatomical crown
part of crown covered by enamel
clinical crown
crown visible in mouth
enamel definition
-covers anatomical crown
-has some translucency
-hardest tissue of body
-has enamel rods/prisms
dentin definition
-forms main portion of tooth
-hard, dense, elastic in nature
-yellow
-healing reaction by making secondary dentin
-had dentinal tubules
pulp definition
-nourishing, sensory
-blood vessels, lymph vessels, connective tissues, nerve tissues
-pulp chamber: part of pulp that is crown
-pulp canal: part of pulp that is in root
-pulp horns: prolongation of the pulp toward cusp
cementum definition
-covers root
-bonelike
-provides attachment of tooth to alveolar bone
-meets enamel at the cementoenamel junction (CEJ)
cervical line
where crown and root meet
crown is covered with
enamel
root is covered with
cementum
