Primary (Deciduous) Teeth: Labeled with letters A to E, starting with the central incisor and ending with the second molar.

A two-digit system (world dental federation system)
Preferred globally by organizations like WHO
First digit: Quadrant number (1-4, clockwise from right maxilla)
Second digit: Tooth number within that quadrant (1-8 for permanent teeth, 1-5 for primary teeth)
Upper right central incisor = 11 (pronounced "one-one")

Universal Notation System

A specific number is given to each permanent tooth & a letter to each deciduous tooth
Permanent Teeth: Numbered 1-32, starting from the right third molar
Deciduous Teeth: Designated with capital letters (A-T), beginning with the maxillary second molar
Sequence is clockwise through all 4 quadrants
The number or letter is preceded by # (e.g., #11) to indicate Universal system.
