Case of the Week: Lateral Dentigerous Cyst (CBCT)

Posted on by Dr. Shawneen Gonzalez

This week I have an interesting case of a lateral dentigerous cyst to share.  A lateral dentigerous cyst is a dentigerous cyst that is coming off the lateral aspect of a tooth.  As with a typical dentigerous cyst, you will be looking for an enlargement of the dental follicle surrounding an impacted tooth.

This case is on the developing permanent mandibular left canine (#22). Check out the images.

Rotated sagittal view from CBCT scan (5mm thickness) showing the radiolucent area is continuous with the follicle around the tooth.

  2. Very nice indeed.
    Was a regular OPG done earlier for a screening?
    Why was the CBCT done for the patient?
    the reason I am asking is – this shows the usefulness of a 3D image in contrat to a 2D image where such things may not be visible at all

    1. I do not know the history but do know the scan was taken to evaluate the canine area. This makes it sound like it was found initially on 2D imaging.
