Dentition
Natural teeth in jawbone
Permanent Teeth
32 permanent teeth
Primary Deciduous Teeth
20 primary deciduous teeth
Incisors, Canines, Premolars, Molars
Types of teeth
Dentition Periods
Primary: 6 months to 6 years, Mixed: 6 years to 12 years, Permanent: 12 years after
Crown
Clinical crown: only the portion visible above gum line
Root
Clinical root: hidden portion of tooth beneath gum line not seen in mouth
Anatomical Crown
Entire part of tooth covered by enamel
Anatomical Root
Permanent part of tooth covered in cementum below CE
Cervical Line
Visible boundary where top crown meets bottom root
Eruption
When teeth emerge from gums
Incisors
8 of 32, cut or incise, straight edge, incisal edge
Canines
4 of 32, cuspid, eye teeth, cusp, pierce or hold food mastication
Premolars
8 of 32, bicuspids, 2 cusps, before molars
Molars
12 of 32, 4 cusp, crushing, grinding
Maxillary
Upper arch of teeth
Mandible
Lower arch of teeth
Human Dentition
Heterodont dentition: different teeth
Diphyodont
2 sets of teeth
Polyphyodont
Many teeth
Nonsuccedaneous
No preceding teeth
Succedaneous
Primary tooth precedes
D.A.Q.T. System
D: dentition (permanent or primary), A: arch (maxillary or mandibular), Q: quadrant (upper right, etc.), T: tooth type (molar, etc.)
Universal Numbering System (UNS)
Permanent: 1-32, start on upper right of patient's mouth 1-16, end on lower right 17-32
International Coding System for Permanent Teeth (INS)
Start numbering with centrals, end with last molar
Tooth Surfaces
Mesial: facing forward, Distal: facing away, Lingual: facing tongue, Labial: facing lips, Buccal: facing cheek, Occlusal: chewing surfaces
Embrasure
Triangular shaped space created by 2 teeth
Contacts
Mesial, distal, proximal space, interproximal space
Division of Teeth
Distal, ingot, patio, apical, middle, cervical, facial third
Root Structure of Teeth
Anatomical root, apex, apical foramen, single root, bifurcated, trifurcated
Multi-rooted Teeth
Terminal root, root trunk, maxillary teeth 3 terminal roots, mandibular teeth 2 terminal roots
