This month, I wanted to show some unusual anatomy cases that I have recently treated. Some of the anatomy is difficult to discern from the preoperative images. However, close examination does reveal that the canal anatomy is not typical. I usually try to visualize the root canal space from the top to the apex of the root. In doing so, I am not only anticipating what my final outcome will look like, but to also search for clues that the canals are atypical. Careful intraoperative imaging as well as tactile feel of what the files are doing provide clues to the root anatomy. Thanks again for your trust in our practice. If you have any questions or comments, please let me know.
