Transposition

Definition: A developmental anomaly where two adjacent teeth switch positions in the dental arch.

Radiographic Features:

Location: Most commonly involves the permanent canine
Edge: Well-defined
Shape: Normal tooth shape for each involved tooth
Internal structure:
- Radiopaque (enamel and dentin)
- Radiolucent (pulp chamber and root canal)
Other: None specific
Number: Involves two adjacent teeth

Key points:

Most frequent transposition involves canine and first premolar
Can occur in maxilla or mandible, but more common in maxilla
May be complete (crowns and roots) or incomplete (crowns only)
Often associated with other dental anomalies

Clinical significance:

Can cause aesthetic and functional issues
May complicate orthodontic treatment planning
Potential for increased caries risk due to abnormal tooth positioning
Treatment depends on severity and patient age (observation, orthodontic correction, or extraction)

Note: Careful evaluation of the entire dentition is important, as transposition may be associated with other developmental anomalies. Early detection allows for better treatment planning and management.
