This week I have a case of anatomy that I more commonly see on CBCT images but have occasionally come across on 2D radiographs; the gubernaculum dentis. The gubernaculum dentis is a canal of connective tissue from a developing tooth bud to the overlying mucosa. It presents as a radiolucent band from the developing tooth bud to the crest of the alveolar ridge.

Pantomograph – gubernaculum dentis as a vertical radiolucent band superior to the crown of the developing right mandibular canine.

CBCT coronal view – the gubernaculum dentis as a horizontal radiolucent band from the developing right mandibular molar to the crest of the alveolar ridge.
If you have any questions or comments about the gubernaculum dentis, please leave them below. Thanks and enjoy!
Absolutely fantastic. Only ever saw this on histology slides.
Thanks. I don’t recall seeing this on histology slides. I may have to try and find some now. 😀
