Radiopaque jaw lesions

Radiopaque lesions of the jaw

Radiopaque lesion or area found on an x-ray? What is it? I’m going to slowly update with more interesting finds. Be aware most of these are bet guesses and not biopsy confirmed, as most do not warrant that. We have a post for radiolucent lesions on panos as well with much of the same information.

An unknown radiopaque area or lesion is a regular find in dentistry.

So what is the calcification that you found on the pano? Typically you can decide by location what the calcification is, but this is not always the case. I have found the following diagram very helpful.

Is there a calcification found on pano?

Idiopathic osteosclerosis or dense bone island DBI

The cause and classification of these is controversial. Biopsy is not necessary unless large changes occur. 25% growth in 6 months or 50% in one year according to Mariani 2009 Oral Implant.

Idiopathic osteosclerosis around teeth numbers 29 and 30.

Idiopathic osteosclerosis is the working diagnosis of this radiopaque jaw lesion.

This one is a gun shot wound patient (GSW). It’s actually just a pellet from a college incident of boys screwing around.

This one is the back to an ear ring. She is 12 and there is no memory of doing this. It was not visible in pano so never found until and orthodontic scan was done.



Some pano labels and a great blog with lots of labels.
