Sorry to be gone for such a long hiatus. I’ve been working on a side project that has taken much more time than expected. If all goes well I’ll be posting in a few months the outcome of that project. Now onto some anatomy. 🙂
The mental foramen is most commonly seen near the apex of the mandibular second premolar. It may be visible anteriorly to the first premolar and posteriorly to the first molar. It presents as a radiolucent round to ovoid entity. When it is superimposed over the apex of a tooth it is important to look at the periodontal ligament space and lamina dura of the tooth to determine a pathosis of tooth origin versus the mental foramen.
If you have any questions or would like to see other examples, please let me know and I’ll see what I can. Thanks and enjoy!
