A) Lower incisors with persistent symptoms despite reinstrumentation. The canals are densely filled and a slight overfill is inconsequential as the patient will see the surgeon the same day for apical surgery. (B) At the completion of the apical surgery with placement of a mineral trioxide aggregate retrograde seal. (C) Six months later the bony defect is nearly completely healed without the use of any graft.
