Dental transposition is best described as which of the following?

Dental transposition is best described as which of the following?

• A. Rotation of tooth around longitudinal axis
• B. Mesial displacement of a tooth
• C. Eruption disorder
• D. Change of neighboring teeth with its place on the dental arch

Answer: (D)

Dental transposition is about two adjacent teeth exchanging their positions in the dental arch, so each tooth ends up in the other’s usual place. This is a genuine positional swap, not just twisting a tooth around its long axis (rotation) or moving a tooth toward the midline without swapping with a neighbor (mesial displacement). It’s also not about the timing of eruption (eruption disorder). The described idea of neighboring teeth changing places in the arch best captures transposition, such as the canine taking the lateral incisor’s spot.
