Retreatment of a tooth with hypercementosis.
Case in which the tooth was retreated at the request of a colleague, due to treatment falling short of the mesial root apex.
The length was checked by the locator, but a new attempt was made at the patient's request.
This time we tried a more invasive approach with foraminal widening, where we observed the path of the foramen, away from the apparent apical region.
Case conducted by Ana Paula Santos, a student in the endodontics specialization program at Chibebe Cursos in Taubaté.

Summary
Root canal retreatment is traditionally considered an "all or nothing" treatment approach. It is usually recommended that all restorative and filling materials should be removed from all roots, regardless of the presence or absence of periapical pathology. In contrast, surgery to endodontics is not viewed as an "all or nothing" treatment approach, Traditionally, only the diseased root(s) are addressed by apical resection and apical filling.
The use of cone beam computed tomography allows a more accurate assessment of the periapical condition of individual roots. This information has introduced a new, conservative treatment alternative for previously endodontically treated teeth with multiple roots showing post-treatment disease. This new approach is called selective root retreatment. Advanced imaging allows the clinician to make predictable treatment decisions regarding the presence or absence of periapical pathology of individual roots, rather than making assumptions about the tooth as a whole. Selective root retreatment combines the non-surgical retreatment treatment approach with the selectivity of surgical root resection. In this way, retreatment can be limited to a single root or roots clearly showing periapical pathology while leaving the root(s) with no visible or perceived pathotic sign untouched.
