**Question:** A 12 year old male patient complains of pain in the upper front teeth region and gives a history of a fall while playing 30 minutes ago. Intra-oral examination reveals intrusion of maxillary right central incisor by 8 mm. What is the most appropriate treatment for this patient?

**Core Concept:**
The presented scenario involves a traumatic dental injury, specifically intrusion of a maxillary right central incisor, which requires a proper management plan to prevent potential complications and restore the tooth to its normal position.

**Why the Correct Answer is Right:**
In this case, the correct answer should focus on addressing the immediate dental injury and preventing further complications. The most appropriate treatment is **D**. Applying a periapical dressing (pulp dressing) is crucial to prevent secondary bacterial invasion, maintain the tooth's vitality, and allow for endodontic intervention if needed in the future.

**Why Each Wrong Option is Incorrect:**
A. Removing the tooth (extraction) is not a suitable option as the patient is young and the tooth is vital. The tooth may need treatment in the future, and extraction would lead to tooth loss and potential orthodontic problems.

B. Applying a periodontal dressing (pocket filling) is not ideal for this case, as it is not designed to prevent secondary bacterial invasion and maintain tooth vitality.

C. Conservative management without a specific treatment method does not address the pressing issue of preventing complications and maintaining tooth vitality.

**Clinical Pearl:**
In traumatic dental injuries, timely and appropriate treatment is essential to prevent complications and ensure long-term tooth survival. This case highlights the importance of considering patient age, tooth vitality, and potential future treatment needs when selecting the most suitable treatment option.

✓ Correct Answer: B. Reposition surgically and stabilize for 4 to 8 weeks by means of a flexible splint with endodontic intervention.
