This patient presented herself with an irreversible pulpitis on her mandibular second molar. Patient had no medical problem and a normal mouth aperture. This very long tooth is in remote position in the arch, its mesial root canals path are into an “S” form. Canal calcifications on top of completely obliterating the pulp chamber, are making the root canals no longer visible in their apical third. Those considerations have been disclosed to the patient in order to allow her to understand the very high degree of difficulty and risks of the root canal procedure. Once the patient consent obtained, we could carry on with the root canal treatment
