Dental Anatomy & Morphology
Sciences dealing w the formation of teeth (crown & root) and how to communicate about them
3 Dentitions
Primary
Mixed
Adult
Primary aka
“Baby” “deciduous”
Permanent aka
“secondary” or “adult”
Succedaneous
Permanent teeth that SUCCEED primary predecessors
Incisors, canines, pre-molars
Nonsuccedaneous
Permanent teeth that DO NOT replace primary teeth (molars, NOT pre-molars)
PRIMARY Incisors (8)
D,E,F,G
N,O,P,Q
(cut/bite)
PRIMARY Canines (4)
C, H
M, R
(tear/pierce)
PRIMARY Molars (8)
A,B,I,J
K,L,S,T
(grind)
PERMANENT Incisors (8)

Crown anatomy
Denton covered by enamel
Root anatomy
Denton covered by cementum
Anatomic Crown
Entire crown covered by enamel
Clinical Crown
Visible part of the crown (not covered by gingiva)
Anatomic Root
Part of root covering by cementum
Clinical Root
Visible root (eek!)
Pulp anatomy
Extends crown to root
Covered by dentin
Pulp parts
Pulp cavity Pulp canal(s) - apical foramen Pulp horn(s) - possible
Alveolus
Bone tooth socket
Alveolar Process
Dental arch: maxillary or mandibular
CEJ
CementoEnamel Juntion
Embrasures
Interproximal space between teeth
