Placement of very sharp pointed instrument into the periodontium to extrude tooth out of the socket, this is called:
## Core Concept
The question pertains to dental procedures, specifically to the method of tooth extraction. The procedure described involves the use of a sharp-pointed instrument to extrude a tooth out of its socket, which is a technique utilized in dental practice.
## Why the Correct Answer is Right
The correct answer, **Luxation**, refers to the process of loosening a tooth within its socket to facilitate extraction. This can indeed involve the use of sharp-pointed instruments (such as elevators) to carefully pry the tooth away from the surrounding bone and periodontal ligament. The goal is to disrupt the periodontal ligament and make the tooth mobile enough to be easily extracted. This technique requires precision to avoid damaging the surrounding bone or tissue.
## Why Each Wrong Option is Incorrect

## Clinical Pearl / High-Yield Fact
A key point to remember is that luxation is a critical step in tooth extraction that requires careful manipulation to avoid complications such as fracture of the tooth or surrounding bone, or damage to the inferior alveolar nerve. The procedure should be performed with caution and under appropriate anesthesia to minimize discomfort and risk.
## Correct Answer: C. Luxation
