Widely used in the U.S for both dentitions
  • A-T - primary
  • 1-32 - permanent

  • the first digit is the quadrant, second digit: tooth's position in this quadrant (1-8 starting with C. incisor)
Palmer Notation Method
"Military numbering System"- produce easy to view graphic mapping.
  • (A-E starting with C. incisor, with L symbols)

Tooth supported by the bone of the tooth socket, located in the alveolar process
Anterior teeth
Incisors & Canines
Posterior teeth
