The ameloblastoma is a benign epitherial odontogenic tumor which resembles the appearance of the enamel origin.Although it usually occurs in third and forth decades of life, it may arise at any age.In 80 per cent of cases the ameloblastoma is located in the mandible. In the mandible about 70 per cent are located in the molar region, and 10 per cent in the incisor region.Recently, we experienced a case of large ameloblastoma with the right impacted canine in an 11-year-old.Radiological examination showed molar region of the mandible and tumor area is right first molar region to left second premolar region.The literature on child ameloblastoma were reviewed.Furthermore, both clinical and histopathological differences of several ameloblastoma were also discussed.
