Anatomy Monday: Gubernaculum Dentis 2


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.
