What does the term ______ mean in relation to tooth movement?

1. Extrusion

2. Luxation

3. Intrusion

4. Rotation

The correct answer is: Luxation

Luxation refers to a situation where there is a displacement or movement of a tooth from its normal position. In the context of tooth movement, luxation commonly involves trauma, which may cause a tooth to become loose and move either partially or completely out of its socket in the jawbone. This term is particularly relevant for dental professionals when assessing injuries or conditions affecting the stability of a tooth. Understanding luxation is crucial for diagnoses and determining the appropriate course of action in dental treatment, such as repositioning the tooth or managing any associated injuries. It directly pertains to the position and stability of teeth in the oral cavity, thereby impacting overall dental health.
