A patient feels that his molar is extruded from the socket and is tender to percussion. This can be due to
**Core Concept**
The patient's symptoms suggest a complication of dental extraction, specifically a condition where the tooth has become displaced from the socket and is causing pain upon percussion. This scenario points to a condition requiring prompt attention to prevent further complications.
**Why the Correct Answer is Right**
The correct answer is likely due to a condition known as **tooth luxation** or **tooth extrusion**. This occurs when a tooth is displaced from its socket during or after an extraction, often due to excessive force or trauma. The tooth may become loose or even completely dislodged, leading to pain and tenderness upon percussion. The surrounding bone and periodontal ligament are also affected, contributing to the patient's symptoms.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not directly relate to the patient's symptoms of tooth displacement and tenderness upon percussion. While a dry socket (alveolar osteitis) can cause pain, it typically does not involve tooth displacement.
**Option B:** This option is incorrect because a periodontal abscess would primarily present with localized pain, swelling, and possibly pus discharge, rather than tooth displacement and tenderness upon percussion.
**Option C:** This option is incorrect because a periapical cyst or granuloma would typically present with chronic pain, swelling, and possibly a palpable mass, rather than acute symptoms of tooth displacement and tenderness upon percussion.
**Clinical Pearl / High-Yield Fact**
A key aspect of managing tooth luxation or extrusion is to stabilize the tooth and prevent further displacement, which can be achieved by using a splint or a temporary crown. This can help alleviate pain and prevent long-term damage to the surrounding bone and periodontal ligament.
**Correct Answer: C. Tooth luxation or extrusion**
