Which of the following procedures is appropriate for managing a fracture in the apical third of the root?

Observation and recall is appropriate for managing a fracture in the apical third of the root because in many cases, especially if the tooth is asymptomatic and the fracture does not compromise the overall health of the tooth or surrounding structures, a conservative approach is often the best initial management strategy. This allows for monitoring the tooth over time to see if any symptoms develop or if the fracture leads to complications such as infection.

In cases where the fracture may not affect the vitality of the tooth or where the patient does not exhibit pain or swelling, careful observation can be a prudent choice. Additionally, teeth with apical third fractures may have the potential for healing or may not require immediate intervention.

This approach is preferable over root canal treatment, immediate extraction, or apicoectomy, which are more invasive and may not be justified if the tooth remains stable. Therefore, taking a watchful waiting approach allows dental professionals to assess the situation closely before deciding on a more aggressive treatment.
