This patient had no complaints but needed new crown and prosthetic dentist asked me to evaluate an endodontic status
Tooth was treated endodontically at least twice. The first attempt was done more than 20 years before, tooth underwent treatment with “Red Russian Paste” which caused obliteration in root canals. The started to hurt 12 years after the first treatment and the second attempt to re-endo was done. DB canal and palatal (partially) canals were negotiated and filled with GP.
