What is an Ellis Class V injury?

Enamel fracture
Fracture involving the cementum
Luxation
Root fracture

The correct answer is: Luxation

A Class V injury is a type of dental injury that involves the luxation or displacement of a tooth. This can occur due to trauma or injury to the mouth and can result in the tooth being pushed inward, outward, or even completely knocked out of its socket. Options A, B, and D all refer to different types of tooth fractures, while option C is the only one that accurately describes a class V injury. It is important to properly identify the type of dental injury in order to provide appropriate treatment and prevent further damage or infection.
