Anatomy - Chapter 8 (Obj 1.2) Flashcards
anatomical crown
is the whole crown of the tooth, whether it has erupted or not
clinical crown
is part of the tooth that can be seen in the mouth
Roots
The root portion or system of a tooth may be single or multiple with bifurcation or trifurcation, that is, the division of the root trunk into two or three roots
Enamel
hard protective tissue that covers the crown of the tooth, hardest tooth tissue, colour varies with thickness, it is thickest at the tip
Dentin
Makes up the bulk of the tooth, in both the crown and the root, “body of the tooth”, softer than enamel, harden then cementum or bone
Cementum
covers root of teeth, light yellow, attaches tooth to bone, softer than dentin & enamel
pulp
soft connective tissue containing nerves & blood tissues, surrounded by dentin
2 parts of pulp - chamber & canal
pulp horn is extension of chamber
Crown
white part of tooth, covered with enamel
CEJ - Cemento-enamel juntion
cementum meets enamel, also called cervical line or cervix
root
part of the tooth covered in cementum, embedded in bone
apex
terminal end of the root
apical foramen
tiny opening in apex of the root for blood vessles and roots to enter
apical
bottom of tooth (bottom of root)
coronal
top of tooth (crown)
radicular
having to do with tooth root, “crotch” of the root, the split
