Dental notation

A committee of the American Dental Association (ADA) recommended the use of the Palmer notation method in 1947.

When speaking about a certain tooth such as the permanent maxillary central incisor, the notation is pronounced “one, one”.

[citation needed] Beware of mixing up the teeth in written form such as 11, 12, 13, 14, 15, 16, 17, 18 between the Universal and ISO systems.

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

Palmer notation is a system used by dentists to associate information with a specific tooth.

Then the count begins at the mandibular left third molar, designated number 17, and continues along the bottom teeth to the right side.

For instance, a dentist may give an instruction to "extract the 24 (UL4)" for the upper left first premolar tooth.
