Which statement defines dental transposition?

Which statement defines dental transposition?

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

Answer: (D)

Dental transposition means two adjacent teeth end up in each other’s places along the dental arch, so their crowns (and often roots) are exchanged rather than simply rotated or erupted in the wrong timing. It’s the actual swap in positions of neighboring teeth, most commonly seen with the maxillary canine and lateral incisor. This differs from rotation (a tooth twisting around its long axis), mesial displacement (a tooth moving toward the midline but staying in its general position), or an eruption disorder (timing or sequence issues without swapping positions). So the statement that describes a change in the relative positions of two neighboring teeth within the arch captures the essence of transposition. Management depends on the case and may range from orthodontic correction to extraction or surgical repositioning, depending on feasibility and esthetic/functional considerations.
