The essential step in the treatment of a tooth with apical resorption is sealing of the apex. This procedure, often referred to as apexification or apical barrier formation, is crucial in cases where the root has not fully formed, or where there is a risk of continued tissue breakdown due to the resorption process. Sealing the apex helps to create a barrier that facilitates the healing and regeneration of the periapical tissues, enabling the tooth to maintain its vitality and function.

This choice directly addresses the pathological condition by providing a physical barrier to prevent bacteria from accessing the apex of the tooth, aiding in the healing of the pulp or periapical area. Additionally, it allows for the possibility of further root development.

In contrast to this, immediate extraction of the tooth could be considered in certain severe cases, but is not the standard initial treatment approach when apical resorption is identified, especially if the tooth can be salvaged. Application of systemic antibiotics might be indicated in the presence of a systemic infection; however, antibiotics alone do not address the structural issues caused by apical resorption. Observation without treatment may delay necessary intervention that might help preserve the tooth's integrity and function. Thus, sealing of the apex is the most appropriate and essential step
