FDI World Dental Federation notation
For crystallographic notation system, see Hermann–Mauguin notation.
FDI World Dental Federation notation is 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.

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.

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