The system is based on the permanent dentition of the pig, which has 11 teeth in each quadrant - three incisors, one canine, four premolars and three molars. The grand total is 44 teeth.

The first digit of the Triadan numbering system refers to the '''quadrant''': right [[Maxilla|maxilla]], left maxilla, left [[Mandible|mandible]], right mandible.
    
The quadrants are '''numbered 1-4''' starting with the right maxilla and ending with the right mandible in a clockwise direction as viewed from the front of the animal.
