Palmer Notation: FDI World Dental Federation Notation

The document summarizes different dental notation systems used internationally to identify individual teeth. The FDI World Dental Federation notation uses a two-digit system where the first number represents the quadrant and the second represents the tooth number from the midline. For permanent teeth, numbers 1-4 represent the upper right, upper left, lower left, and lower right quadrants. For primary teeth, numbers 5-8 are used instead.

FDI World Dental Federation notation

The FDI World Dental Federation notation is widely used by dentists internationally to associate
information to a specific tooth. Developed by the Fédération Dentaire Internationale (FDI), it is also known
as ISO 3950 notation. The FDI system uses a two-digit numbering system in which the first number
represents a tooth's quadrant and the second number represents the number of the tooth from the midline
of the face.

For permanent teeth, the upper right teeth begin with the number, "1".

The upper left teeth begin with the number, "2".

The lower left teeth begin with the number, "3".

The lower right teeth begin with the number, "4".

For primary teeth, the sequence of numbers goes 5, 6, 7, and 8 for the teeth in the upper right, upper left,
lower left, and lower right respectively.

For example: retention of a deciduous molar tooth in the otherwise regular intact lower right jaw, position
5, would be noted as: 41, 42, 43, 44, 85, 46, 47, 48.
