Etiology: arise from epithelial or mesenchymal remnants of tooth-forming tissues, such as the remnants of the rest of the enamel organ, dental lamina, Hertwig sheath, the rest of the Malassez, rest of Serres , basal cells or the oral mucosa, or the reduced enamel epithelium
Transmission: NA
Characteristics: painless swelling usually in the posterior mandibular region, buccal and lingual expansion in the area, ameloblastoma may cause root resorption, and mobile teeth as the neoplasm extends
Dental Implications: It can break through the cranial cavity as it expands; when they are discovered in the maxilla, they may result in death due to direct extension into vital structure; lesions become more difficult to manage as they extend through the bone into the soft tissues
Treatment: excision
Prognosis: good when timely treated but ameloblastomas may recur and untreated they may result in death due to the expansion and tissue destruction
