Tooth Transposition can be described as an interchange in the position of two teeth within the same quadrant of a dental arch.

Canine transposition is reported to be the most common in the human dentition.

The incidence of canine-premolar transposition is reported to be 0.135 - 0.510%.

The reason for canine transposition is unclear, but it seems to be closely related to genetically influenced retained deciduous canines and a history of trauma.
