{{for|crystallographic notation system|Hermann–Mauguin notation}}FDI World Dental Federation notation is a dental notation widely used by dentists internationally to associate information to a specific tooth.[1]Developed by the FDI World Dental Federation, World Dental Federation notation is also known as ISO 3950[2] 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 below correspond to the patient's left and right. Table of codes FDI two-digit notation| Permanent teeth |
|---|
| patient's upper right | patient's upper left |
|---|
| 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | | 48 | 47 | 46 | 45 | 44 | 43 | 42 | 41 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | | patient's lower right | patient's lower left |

How the codes are constructedSyntax: Sometimes a dot is inserted between quadrant code and tooth code in order to avoid ambiguity with other numbering systems. Quadrant codes| 1 | upper right permanent teeth | | 2 | upper left permanent teeth | | 3 | lower left permanent teeth | | 4 | lower right permanent teeth | | 5 | upper right deciduous teeth | | 6 | upper left deciduous teeth | | 7 | lower left deciduous teeth | | 8 | lower right deciduous teeth | Tooth codes| 1 | central incisors | | 2 | lateral incisors | | 3 | canines | | 4 | 1st premolars (permanent teeth) / 1st molar (deciduous teeth) | | 5 | 2nd premolars (permanent teeth) / 2nd molar (deciduous teeth) | | 6 | 1st molars (permanent teeth) | | 7 | 2nd molars (permanent teeth) | | 8 | 3rd molars (permanent teeth) | |
Examples: - "13" = permanent upper right canine
- "32" = permanent lower left lateral incisor
