Ameloblastoma (earlier Adamantinoma) is the second most common odontogenic neoplasm after Odontoma. It is the most
common(61.5%) odontogenic neoplasm in India. It is a tumour originating from the odontogenic epithelium without any effect on
the mesenchyme leading to excessive growth and destruction of the underlying bone. Most authorities consider Ameloblastoma to
be of a varied origin, although the stimulus initiating the process is unknown.
