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

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

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
