Clinical and radiological behaviour of ameloblastoma of the jaws

ABSTRACT

Ameloblastoma is the most frequent odontogenic benign but locally invasive neoplasm consisting of proliferating odontogenic epithelium with various amounts of surrounding fibrous tissue. The purpose of the study was to evaluate the clinical and radiological features of patients with mandibular and maxillary ameloblastoma at Khyber College of Dentistry Peshawar. The study was carried out on 19 biopsy confirmed cases of ameloblastoma, in Oral and Maxillofacial Surgery unit Khyber College of Dentistry Peshawar for a period of 1 years and two months me, from January 2004 to February 2007 RESULTS The age range of patients with ameloblastoma was from 10 years to 58 years with a mean age of 26 0 years SD +/- 11.6. Most of the patients were affected in their second and third decade of life i.e., 21.1% and 52.7% respectively Male to female ratio was 1.41. The mandible was predominantly involved by the tumour 84% while maxilla was involved in 16% of cases. Posterior mandible [63.2%] and anterior maxilla [10.5%] were the favorite site for the tumour in mandible and maxilla respectively The most common presenting complaint of the patients with ameloblastoma was painless swelling [63%]. Multi-locular radiolucency [57.9%] was the most common radiological pattern of the tumour. Ameloblastoma was common In younger age group where posterior part of the mandible was the most common site of involvement Painless swelling ha', been the most common clinical presentation Multi-locular radiolucency was the common radiological presentation in this study
