Oral Anatomy, Dentition, Salivation

crown

- a

- the visible part of the tooth above the gumline

neck

- b

- the junction between the crown and the root at the gumline

root

- c

- the part of the tooth embedded in the socket

- number of _________ varies (single, double, multiple)

furcation

- the area where the roots diverge in multi-rooted teeth

- common site for periodontal disease

enamel

- blue arrow

- hardest substance in the body, protects the tooth

enamel

- 1

- hardest substance in the body, protects the tooth

dentin

- red arrow

- forms the bulk of the tooth and provides support

- continues to form throughout life

pulp

- 1

- contains blood vessels, nerves, and connective tissue

- provides nutrients to tooth and allows for sensation

dentin

- 2

- forms the bulk of the tooth and provides support

- continues to form throughout life

cementum

- 2

- covers the root, attaches the tooth to the periodontal ligament

- important for tooth anchorage

pulp

- 3

- contains blood vessels, nerves, and connective tissue

- provides nutrients to tooth and allows for sensation

cementum

- 4

- covers the root, attaches the tooth to the periodontal ligament

- important for tooth anchorage

apical foramen

- 3

- passage for the nerves and blood vessels

periodontal ligament

- 4

- connects the gums to the cementum on root

apical foramen

- 5

- passage for the nerves and blood vessels

periodontal ligament

- 6

- connects the gums to the cementum on root

dental pad

- ruminants

- modified because of no upper incisors

mesial surface

- red

distal surface

- blue

lingual/palatal surface

- green

- towards tongue

labial/buccal surface

- yellow

- towards lips/cheeks
