Universal numbering system. This is a dental practitioner view, so tooth number 1, the rear upper tooth on the patient's right, appears on the left of the chart. The Universal Numbering System, sometimes called the "American System", is a dental notation system commonly used in the United States. [1] [2]
FDI World Dental Federation notation (also "FDI notation" or "ISO 3950 notation") is the world's most commonly used dental notation (tooth numbering system). [ 1 ] [ 2 ] It is designated by the International Organization for Standardization as standard ISO 3950 "Dentistry — Designation system for teeth and areas of the oral cavity".
With the move from written dental notes to electronic records, some difficulty in reproducing the symbols has been encountered. [4] On a standard keyboard 'slash' and 'backslash' may be used as a crude approximation to the symbols with numbers placed before or afterwards; hence 3/ is 3 ⏌ and /5 is ⎾ 5.
The upper teeth are denoted I 1, I 2, C −, Pm 3, Pm 4, M 1, M 2, and M 3. Left or right has to be specified. The lower teeth are I 1, I 2, C −, Pm 3, Pm 4, M 1, M 2, and M 3. The reason the premolars are labeled 3 and 4 is that in earlier primates there were two other premolars between them and the canines. [5]
