Answer 2

Answer:

Although it is always considered a benign odontogenic tumor, ameloblastoma is slow growing, locally aggressive, and has a high propensity for local recurrence if not removed completely. Some authors tend to regard it as a potentially malignant tumor [1, 2], but metastasis is rare.
