'FDI World Dental Federation notation' is widely used by dentists internationally to associate information to a specific tooth.
[1]
Developed by the
Fédération Dentaire Internationale (FDI), 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, however, nonetheless correspond to the patient's left and right, respectively.
