Errors in endodontic treatment. They are allowed by everyone and are different. Over time, they become less in practice (the main thing is not more), and sometimes what you considered a success before, you begin to consider a failure. For this reason, the philosophy of professional error is a tactical concept. In this case, perforation when searching for MB2, which is a fairly common variant of furcation perforation. I still understand how such a perforation can be instrumentate like a canal (working length??). But fundamentally I don’t understand how it can be obturated!? It can’t be dried! It’s bleeding. The tooth was treated endodontically. Chronic periapical abscess with sinus tract. (periradicular, furcations) CBCT no. The RG - little less than nothing, everything is superimposed with any angulation. At this moment, the sinus tract has closed. I am watching whether or not there will be a recession to the level of perforation, since crystal perforations are dangerous. Let’s see.
