The prognosis for teeth with apical resorption is classified as?

The prognosis for teeth with apical resorption is considered good if the apex can be effectively sealed. Apical resorption is a condition where the root tip of a tooth gradually loses structure, often due to a variety of factors such as trauma or infection. When a dentist is able to intervene and successfully seal the apex, it can help prevent further resorption and create a more favorable environment for the tooth to heal.

The sealing of the apex, typically achieved through endodontic treatment, helps to eliminate infection and stabilize the tooth's structure, improving the chances of maintaining the tooth in function. Factors that contribute to a positive outcome include the extent of the resorption, the overall health of the tooth, and the success of the sealing procedure.

In contrast, the other options suggest conditions that either imply poor prognosis or depend on variable clinical interventions that may not guarantee success. Focusing on sealing the apex provides a proactive approach to managing apical resorption and underlines why prognosis is optimistic when this critical step is achieved.
