Which one of the following techniques is most likely to be carried out to save a tooth from extraction when the patient is suffering from irreversible pulpitis?

Tooth preservation in cases of irreversible pulpitis often requires a procedure that effectively removes the affected pulp tissue, as the pulp is no longer able to heal due to irreversible damage. A pulpectomy involves the complete removal of the pulp tissue inside the tooth, followed by cleaning and shaping the root canals and sealing them. This procedure aims to eliminate infection and restore function, ultimately saving the tooth from extraction.

While other procedures might address pulp issues, they do not specifically cater to irreversible pulpitis as effectively as a pulpectomy. For instance, apicectomy is a surgical procedure that involves removing the tip of the tooth's root but is typically used in instances where there is a persistent infection after root canal treatment, not as a first attempt for irreversible pulpitis. Pulp capping is usually indicated for reversible pulpitis, where the pulp is still vital, and is used to protect the pulp tissue, which does not apply here. Pulpotomy may be suitable for cases where part of the pulp is affected but the tooth is not destined for extraction; however, it is primarily employed in children or in situations where the pulp can still potentially heal. Hence, the most appropriate technique for irreversible pulpitis is, indeed, pulpectomy, making it the
