FDI World Dental Federation notation

FDI World Dental Federation notation is a dental notation widely used by dentists internationally to associate information to a specific tooth.[1]

Developed by the FDI World Dental Federation, World Dental Federation notation is also known as ISO 3950[2] notation.

Orientation of the chart is traditionally "dentist's view", i.e. patient's right corresponds to notation chart left. The designations "left" and "right" on the chart below correspond to the patient's left and right.

Table of codes

X-ray of the teeth and jaw showing the normal permanent teeth. The last two teeth on the patient's left (the dentist's right), 28 and 38 - the maxillary and mandibular third molars (popularly the upper and lower wisdom teeth) are severely impacted.

14 24 maxillary first premolar 2
44 34 mandibular first premolar 1
15 25 maxillary second premolar 1
45 35 mandibular second premolar 1
16 26 54 64 maxillary first molar 3
46 36 84 74 mandibular first molar 2
17 27 55 65 maxillary second molar 3
47 37 85 75 mandibular second molar 2
18 28 maxillary third molar 3
48 38 mandibular third molar 2

How the codes are constructed

Syntax: <quadrant code><tooth code>

Sometimes a dot is inserted between quadrant code and tooth code in order to avoid ambiguity with other numbering systems.

Quadrant codes
1	upper right permanent teeth
2	upper left permanent teeth
3	lower left permanent teeth
4	lower right permanent teeth
5	upper right deciduous teeth
6	upper left deciduous teeth
7	lower left deciduous teeth
8	lower right deciduous teeth

Tooth codes
1	central incisors
2	lateral incisors
3	canines
4	1st premolars (permanent teeth) / 1st molar (deciduous teeth)
5	2nd premolars (permanent teeth) / 2nd molar (deciduous teeth)
6	1st molars (permanent teeth)
7	2nd molars (permanent teeth)
8	3rd molars (permanent teeth)

Examples:

"13" = permanent upper right canine
"32" = permanent lower left lateral incisor
