Flashcards

Palmer Notation

A system using two crossed lines to represent the four quadrants of dental arches, assigning numbers to permanent teeth (1-8) and letters to primary (deciduous) teeth (A-E).

FDI Notation

A two-digit system (1.1, 2.3, etc.) used worldwide to identify teeth by quadrant and position within the quadrant(maxillary and mandible) .

Permanent Teeth (FDI)

Permanent teeth in FDI notation are given a 2-digit number. The first digit represents the quadrant, and the second digit identifies the tooth within that quadrant (1-4 for permanent and 5-8 for primary; 1-8 permanent, 1-5 primary).

Primary Teeth (FDI)

Primary teeth in FDI notation are given a 2-digit number where the first digit represents the quadrant (5-8). The second digit indicates the position within the quadrant (primary teeth: 1 to 5).

Study Notes

Notation Systems for Teeth

Used to identify tooth type and location in dental arches
Quick reference for clinical records

Palmer Notation System

Used in Egypt
Teeth arranged in 2 crossed lines representing 4 quadrants
Permanent Teeth: Numbered 1 to 8, starting with the central incisor and ending with the third molar.
Primary (Deciduous) Teeth: Labeled with letters A to E, starting with the central incisor and ending with the second molar.

FDI Notation System

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.
