Unit 1 Introduction to Dental Anatomy

surface thats toward the face (general area)

facial

surfaces thats toward the lips (infront of teeth)

labial

surface thats toward the cheeks (sides of mouth)

buccal

surfaces thats toward the tongue (behind teeth)

lingual

towards the midline

mesial

away from the midline

distal

surface facing the next tooth

proximal

surface for chewing

occlusal

surface for cutting edge

incisal

what makes up the dental arch

teeth and alveolar bone

supports mandibular teeth, forms lower face and floor of mouth, articulates w tmj

mandibular functions

supports maxillary teeth, forms hard palate, supports facial structure, contributes to nasal and orbital cavities

maxillary functions

this arch is static ( fixed)

maxillary

this arch is dynamic (moveable)

mandibular arch

this arch has paired bones

maxillary arch

this arch has a single bone

mandibular arch

this arch has a hard palate

maxillary arch

this arch has a lower jaw

mandibular arch

what is quadrant 1

maxillary right

what is quadrant 2

maxillary left

what is quadrant 3

mandibular left

what is quadrant 4

mandibular right

what is occlusion

teeth contacts between the top and bottom

hardest substance in body that protects dentin

enamel

under enamel and is the bulk of the tooth

dentin

soft inner tissue w/ nerves and blood vessels

pulp

crown that is covered by enamel and constant

anatomical crown

crown that is visible and can change

clinical crown

line that surrounds the cervical region and can be subjected in the “crown”

gingiva line

line that is the junction of enamel and cementum, “root”

CEJ

this includes the : gingiva, periodontal ligament, alveolus, and cementum

periodontium

thin bone layer of the root of the tooth

cementum

root furcation of two roots

bifurcation

root furcation of three roots

trifurcation

1 tooth type

homodont

multi-tooth type

heterdont

two sets of teeth

diphyodont

continuous replacement

polyphyodont

20 teeth and no premolars

deciduous

another word for deciduous

primary teeth

ages 6-12

transition

32 teeth

permanent teeth

primary teeth sheds

exfoliation

replaces primary teeth

succedaneous

permanents that dont replace

non succedaneous
