Numbering systems for notation of the teeth

Palmer notation
system •Each tooth in a quadrant takes a letter (A
– E for deciduous) or a number (1 – 8 for
permanent) indicating its order when
counting from the midline

FDI numbering system
•Proposed by FDI & adopted by WHO
•Each tooth is allocated a two-digit number;
the left designates the quadrant and the
right designates the tooth order
•Examples
–Mandibular right permanent canine 43
–Maxillary left deciduous lateral incisor 62

Universal numbering system
•Palmer – difficulty in keyboard typing
•ADA adopted the universal system in 1968
•Letters for deciduous teeth
–Consecutive from A to T
–Following a clockwise order from maxillary right second molar to
mandibular right second molar
•Numbers for permanent teeth
–Consecutive from 1 to 32
–Following a clockwise order from maxillary right third molar to
mandibular right third molar
