Which procedure is an example of endodontic treatment?

Endodontic treatment focuses specifically on the dental pulp and tissues surrounding the roots of a tooth, primarily involving procedures aimed at saving or treating a tooth that has become infected or is otherwise compromised. A root canal is the quintessential example of endodontic treatment; it involves the removal of the infected or damaged pulp from inside the tooth, followed by cleaning, shaping, and sealing the empty space to prevent further infection.

Tooth cleaning and teeth whitening are more concerned with the external appearance of the teeth and their overall health rather than addressing issues related to the pulp or inner structures of the tooth. These procedures do not involve the internal anatomy of a tooth and thus do not fall under the category of endodontics. Similarly, braces installation pertains to orthodontics, which focuses on the alignment of teeth and jaw structures, distinct from the treatment of dental pulp. Therefore, root canal treatment is the only procedure listed that qualifies as an endodontic treatment.
