A tooth transposition occurs when two teeth exchange their normal positions, most often involving the permanent canine and lateral incisor. Radiographs are useful for recognizing this condition by showing an unusual sequence of teeth. Impacted teeth in the wrong positions can be surgically exposed and prosthetically altered under local anesthesia to improve function.

1. Transposition

2. General information
Tooth may be found occupying an unusual position
in relation to other teeth, in the dental arch, that is
two teeth apparently exchanging their position

3. Clinical features
Permanent canine is most often involved with its
position interchange with lateral incisor
second premolar is infrequently found between
first and second molar
transposition of Central and lateral incisor is rare
transposition does not occur in primary dentition

4. Radiographic features
It can be recognised
on radiograph by an
unusual sequence of
teeth in dental arch

5. Management
These teeth can be
prosthetically altered
to improve function
anaesthetics
