Radiographic Impression:
The 33 is impacted in a vertical direction, with the crown thinning and possibly interrupting the lingual cortex. The crown is in contact with the lingual aspect of the 32 and 31 with no external resorption. A lingual surgical approach is suggested to uncover the crown of the 33 and place an orthodontic device.

The following are selected images from the volume illustrating major findings
A large mixed density area is associated with the apex of the canine. It presents with multiple areas of relatively lower density with sclerotic pattern and is consistent with a focal osseous dysplasia, a self-limiting benign entity that does not require any additional assessment.

The primary canine is retained with severe root resorption and the presence of an irregular in shape high density inferior to the root situated within the thickness of the alveolar crest. This is a small compound odontoma.
