When should a pulpectomy be performed if the root is fully formed on a intruded tooth?

A pulpectomy, which involves the removal of the pulp tissue from the root canal system, is indicated in an intruded tooth once the root is fully formed when there is a concern for possible pulp necrosis. In the case of fully formed roots, the timing of the pulpectomy is crucial in determining the tooth's prognosis.

Performing the pulpectomy within 1-3 weeks after the injury is supported by clinical evidence that this time frame allows for the assessment of pulp vitality and can help mitigate potential complications such as the development of pulp necrosis. Intrusion injuries can result in ceasing the blood supply to the pulp, leading to inflammatory responses or necrosis; thus, intervention within this time frame is beneficial to improve outcomes.

After the initial weeks, the risk of necrosis increases, and waiting too long may lead to irreversible damage to the pulp, necessitating additional treatment and potentially threatening the tooth's survival. Performing the procedure earlier allows for better healing and can preserve the vitality of surrounding structures.

Other options, such as performing the pulpectomy immediately after the trauma, would not allow sufficient time to monitor for natural pulp healing or changes, while delaying for several months risks complications without proactive management. Lastly, monitoring for signs of
