BACKGROUND: Ameloblastoma is a neoplasm classified as a benign epithelial 
odontogenic tumor of the jaws, grow slowly and are locally invasive. The aim of 
the present study was to investigate the incidence, treatment, and complication 
of patients with ameloblastoma in East-Indonesia during six years retrospective 
study.
MATERIAL AND METHODS: This retrospective study included 84 patients who were 
diagnosed with ameloblastoma from 2011 to 2016. There were 56 patients with 
treatment data available. Data from each patient, including gender, age, 
histologic type, the size of the tumor, radiologic form, tumor location, type of 
treatment, and complication were reviewed and analyzed retrospectively.
RESULTS: Fourteen patients were diagnosed with unicystic ameloblastoma (25%), 
thirty two patients with multicystic follicular ameloblastoma (57%) and ten 
patients with an unspecified multicystic ameloblastoma (18%). A total of about 
35 patients were treated conservatively (62.5%) and 21 patients were treated 
radically (37.5%). Swelling was present as a pre-operative complication in all 
56 cases (100%). There were no complaints concerning speech.
CONCLUSIONS: The majority findings of the histologic type were multicystic 
ameloblastoma and their location were in the mandible. Most ameloblastoma were 
treated conservatively and reconstructions were made with only titanium plates 
and not bone graft.
