This is a common area for furcation canals to exist, 2. Without a history of trauma on this tooth, any root fractures will likely be vertical, especially after an endo, 3. If this is a horizontal root fracture, the fracture line would probably be visible through the entire root structure rather than ending at the canal space. A lesion would develop circumferentially to the fracture line rather than just in the furcation. 4. I agree, there's probably no perf in the P root. The evidence and history, however, is consistent with a strip perforation in the MB root. The lesion is originating in the so-called "Danger Zone" and there was minimal straight-line access to the MB canal system in the initial endo. This leads to the potential of even further thinning of root structure in the wrong spots during further endo treatment or post space preparation. Thanks for the comment!

what is the prognosis for this tooth? extraction and implant? if i were this dentist, i’d refund the money. actually, one of the “picture perfect” endo’s i completed about 6 months ago failed and i cut the guy a check as soon as he went to the specialist for the consultation. it just seems like the right thing to do.
