What is the reason for considering the extirpation of an intruded tooth with a closed apex within 7-14 days?

• A. To prevent inflammatory root resorption
• B. To promote faster healing
• C. To prevent tooth discoloration
• D. To facilitate orthodontic movement

Answer: (A)

In the context of managing an intruded tooth with a closed apex, the timing of extirpation, or removal of the pulp tissue, is critical for preventing inflammatory root resorption. When a tooth is intruded, it is displaced into the alveolar bone, causing damage to the periodontal ligaments and surrounding tissues. This trauma can lead to a cascade of inflammatory responses that ultimately compromise the vitality of the tooth and the surrounding structures. If the pulp is not extirpated within the 7-14 day window after the intrusion occurs, the likelihood of inflammatory root resorption increases significantly. This resorption is a result of the body's response to the injury, where inflammatory cytokines and other mediators activate resorptive processes on the tooth roots. By intervening during this critical period, the risk of these complications is minimized, preserving the integrity and potential for the tooth to remain functional. Promoting faster healing, preventing tooth discoloration, and facilitating orthodontic movement are important considerations in dental trauma management, but they are secondary to the primary goal of maintaining the tooth's structure through the prevention of inflammatory root resorption.
