 Good morning. Happy Friday. Today's Friday flop is actually from one of my cases Monday. I had a few of these come in similar to this on pulp therapy. This tube was necrotic at the time when I did a pulpectomy on it. And we tend to try to save second molars and canines. If we lose a canine, we have to extract the contralol or canine to keep symmetry. And then the second molar can help prevent the 16-molar from coming in and taking space away from the premolar. So in this case, this was a one where we didn't have the 16-molar erupted. I was trying to save it. And it ended up not working out and developing an acute aqueous abscess. And this one, looking back, really, really did the bite wing. It's pretty obvious the error here that I did not reduce enough occlusally and we had an open margin. And I think that is why this case failed. So I'll be looking at the back and trying to make sure that I get my crown seated all the way down. And the next time I do one of these, I hope you have a great Friday. And look forward to sharing the rest of them with you next week.
