When writing or discussing about teeth, dental practitioners use dental notation, commonly known as the ANSI/ADA/ISO Tooth Numbering System. It is a method of visually recording the presence and positioning of teeth and linking the data to each of them within a dentition.

How Many Dental Notations Are There?

The Palmer notation method, the universal numbering system, and the FDI international dental federation notation (ANSI/ADA/ISO Tooth Numbering System) are the three most often used dental notations.
