rarefying osteitis

It's diagnosis becomes important so the treating doctor doesn't confuse it for another periapical disease such as rarefying osteitis or condensing osteitis.

Being that it is the most common fibro-osseous lesion, although relatively rare compared to rarefying osteitis, incorrect diagnosis would lead to many unnecessary root canal treatments.

Rarefying osteitis is a general term for a radiolucent lesion on a radiograph usually diagnosed as a periapical abscess or a periapical cyst.
