Q

What is the anatomical system for numbering teeth? What is the Triadan system?

A

Anatomic: Teeth labled based on type of tooth (M=molar, I=incision, C=canine) plus a number to the right or left of the letter as a sub or superscript (side of mouth, mandible vs maxilla)

Triadan: each tooth assigned 3-digit number; right maxilla = quadrant 1 = number start with 1, etc. (for deciduous 5, 6, 7, 8 instead of 1, 2,3,4)
