A tooth may require one of several types of endodontic treatment to avoid extraction. Which type involves the use of endodontic files during its completion?

The correct answer identifies pulpectomy as the type of endodontic treatment that involves the use of endodontic files. In a pulpectomy, the procedure requires the removal of the entire pulp tissue from the tooth, which necessitates the use of specialized instruments known as endodontic files. These files are designed to shape and clean the interior of the root canals, ensuring they are free of infected tissue and debris before filling them with a biocompatible material.

This step is crucial not only to eliminate infection but also to prepare the canals for sealing, thus preserving the tooth and preventing further complications. The successful execution of a pulpectomy directly contributes to pain relief and the long-term health of the tooth.

Understanding the different endodontic treatments is essential for dental professionals, as it informs the approach to preserving teeth that are at risk of extraction due to issues like decay or infection. The other options, such as apicectomy, pulp capping, and pulpotomy, involve different procedures without the complete removal of the pulp using endodontic files in the same manner as a pulpectomy.
