This was a case that had a large area of infection. A previous root canal was performed with Thermofil. I decided to retreat this tooth #15. I disassembled the previous endodontic treatment and placed calcium hydroxide for 2 weeks. He return and I had to repair a transportion with MTA (Dentsply) from the previous treatment and an MB2 was located. This is a 1 year recall and the patient is asymptomatic showing very nice healing. The barium which is an opacifier in the CaOh is still present in some areas. Root Canals Work!
