Ameloblastoma is a benign tumour arising from the jaw. It is a locally invasive tumour of epithelial odontogenic origin. It is common in the third and fourth decade. Multicystic type of ameloblastoma is a locally aggressive lesion. Ameloblastoma is a locally aggressive benign tumour of the mandible, which is painless and slow growing. It constitutes 1% of cysts and tumours of the jaw. It has equal gender predilection. Commonly ameloblastomas are found in molar ramus region. When the maxilla is involved, it has the potential to spread insidiously to involve the infra temporal fossa, orbit and skull base; thus a thorough assessment is essential. Ameloblastoma either presents as unilocular or multilocular lesion in radiograph. It has a honey comb appearance. In extensive lesions involving mandible and maxilla we require CT and MRI to establish the diagnosis. Ameloblastoma needs a complete excision and reconstruction. It is also treated by enucleation, curettage and surgical excision. Recurrence rate is approximately 18 to 20 %.
