Thank you. Hindsight is 20/20, and I should have looked more closely at the radiograph of the tooth I chose for posterior endo and reviewed it with others. There were pulp stones, and I was unable to access any of the canals. So I pretty much knew I failed before I even walked out of the room, because only way to pass was if I got a 5 on my other tooth, which was very unlikely. Operative was on a patient I never worked on before and there was extensive demin, and not ideal teeth. I did not get any pink slips for leaving anything, but I had mod requests denied, and probably other things they disagreed with, which just added up. I was well prepared, well-read, and really tried to go by the standard for a 5, but there is room for subjectivity obviously, and I just wasn't in the same frame of mind as the examiner. So I did anticipate the potential failure of that section, as well. I wish I could have had ideal lesions, but I did what I was able to get. The endo was just a completely unfortunate situation. I didn't really have a lot of teeth to pick from, but I know I managed to select the worst one. I know I had better because I practiced on it. Again, hindsight is 20/20 on looking much more critically at the radiograph (and getting opinion of others).
