FDI World Dental Federation notation

FDI World Dental Federation notation is widely used by dentists internationally to associate information to a specific tooth.

Contents

Developed by the FDI World Dental Federation, 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 below correspond to the patient's left and right.

Table of codes

Codes, names, and usual number of roots: (see chart of teeth at Wikipedia entry: Universal Numbering System)

  • 11 21 51 61 maxillary central incisor 1
  • 41 31 81 71 mandibular central incisor 1
  • 12 22 52 62 maxillary lateral incisor 1
  • 42 32 82 72 mandibular lateral incisor 1
  • 13 23 53 63 maxillary canine 1
  • 43 33 83 73 mandibular canine 1
  • 14 24 maxillary first premolar 2
  • 44 34 mandibular first premolar 1
  • 15 25 maxillary second premolar 1
  • 45 35 mandibular second premolar 1
  • 16 26 54 64 maxillary first molar 3
  • 46 36 84 74 mandibular first molar 2
  • 17 27 55 65 maxillary second molar 3
  • 47 37 85 75 mandibular second molar 2
  • 18 28 maxillary third molar 3
  • 48 38 mandibular third molar 2

    • How the codes are constructed

    Syntax: <quadrant code><tooth code>

    Sometimes a dot is inserted between quadrant code and tooth code in order to avoid ambiguity with other numbering systems.

    Examples:

  • "13" = permanent upper right canine
  • "32" = permanent lower left lateral incisor
