ABSTRACT
An Ameloblastoma is one of the most common odontogenic tumors. The treatment of ameloblastoma has been controversial because of this disease entity as a slow-growing, locally invasive tumor with high rate of recurrence. Recurrence rate of ameloblastoma are reported 15% to 25% after radical treatment and 75% to 90% after conservative treatment. On the other hand, Robinson and Gardner reported that the recurrence rate after conservative treatment of unicystic ameloblastoma was lower than those of multicystic or solid lesion. In this report, what we want to show is to review the articles to find out pros and cons of conservative treatment of ameloblastoma. In addition we would like to discuss which requies conservative treatment or radical treatment are more acceptable through our case report.
