no, but still classified as from non-odontogenic origin
|
|
|
Does globulomaxillary cyst diverge the roots of adjacent teeth?
|
yes, it pushes on them

Is aneuraysmal bone cyst aggressive
|
yes, root resorption, multilocular, divergence of roots and teeth, acts like a tumor doing a lot of damage
|
|
|

Could be a large nodule, but we're talking about the alteration in the DNA of the cell. Functionally results in a change that gives it a hypertrophic growth that rapidly spreads. Tumor has all abnormal cells inside of it.
