Ameloblastomas may also be similar to simple bone cysts in some cases. An important differential sign is the root resorption found in the teeth affected by ameloblastomas, and not, in contrast, in other cysts, such as
Does Ameloblastoma resorb roots?
Radiographs of 122 cases of a series of nonmalignant simple jaw cysts and ameloblastomas were examined and the frequency of resorption of adjacent tooth roots compared. The ameloblastomas proved to have a root resorptive potential far greater than the cystic lesions considered.
What causes root resorption?
In most cases it is due to a physical injury to the tooth, as from an impact, chemical, or burn. The trauma leads to inflammation that in turn results in resorption. Other causes include pulp necrosis, periodontal treatment, orthodontics, or poorly done, non-professional tooth whitening.
