When size matters: The management of apical inflammatory root resorption and how to adequately seal the altered anatomy in just one visit

During this presentation, I will analyze the techniques, materials and tools required for the obturation of wide and irregular apexes, focusing on the mineral trioxide aggregate single-visit approach. This procedure will allow any dentist to solve complex and complicated situations in a single visit.

In most cases in which we encounter a failure of the initial endodontic treatment, the root canal anatomy we are confronted with is altered. Neglecting this structural modification might lead to a series of procedural errors, which in the end will result in another unsuccessful treatment attempt. Periapical lesions cause the destruction of the surrounding hard tissue, leading to an irregular dimension and shape of the apical foramen. This problem might also occur owing to different iatrogenic events during previous treatment attempts. It is important to have the necessary theoretical knowledge and practical skills to properly seal these root canals even if the situation, at times, might seem hopeless.
