Which of the following dental injuries is classified as a traumatic luxation injury that is NOT axial (non-axial)?
Show answer and explanation
Correct answer: C. Lateral luxation
C) Lateral luxation — CORRECT (non-axial injury).
Lateral luxation involves displacement of the tooth in a non-axial direction (labially, lingually, or laterally), usually accompanied by fracture of the alveolar socket wall. It is the prototypical non-axial luxation injury.
A) Avulsion: Complete displacement of the tooth from the socket — axial direction but complete.
B) Intrusion: Forced INWARD (axially) into the socket — an axial injury.
D) Extrusion: Partial displacement OUT of the socket — also axial.
