Ameloblastoma: Report of Two Cases and a Brief Literature Review

Ameloblastoma is an uncommon odontogenic neoplasm that accounts for approximately 10% of all tumors originating from gnathic bones. Although its growth is localized, the tumor can also be infiltrative and persistent; however, its behavior is usually benign. The mandible is the most commonly affected...
