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]

[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 .
In dentistry, a periodontal probe is a dental instrument which is usually long, thin, and blunted at the end.
