Several systems exist for explicitly denoting a tooth's location in the dentition.
|
Dentition |
Sets of Teeth |
|---|---|
|
deciduous (child) |
4 sets (left and right, maxillary and mandibular) of 5 teeth = 20 |
|
permanent (adult) |
4 sets of 8 teeth = 32 |
Notation systems:
(1) American (USA)
(2)European
(3) FDI
(4) Zsigmondy-Palmer, Chevron, or Set Square system
Usually diagrams are from the examiner's perspective
(1) The rightmost position is the patient's final left molar.
(2) The leftmost position is the patient's final right molar.
