What does an ameloblastoma arise from?

An ameloblastoma is a benign but locally aggressive tumor that arises primarily from the remnants of odontogenic epithelium. These remnants can include the enamel organ, dental lamina, and other tissues involved in the development of teeth. The tumor is characterized by its origin in the tissues that are typically involved in tooth formation, leading to the proliferation of the odontogenic epithelium, which gives rise to the neoplastic growth.

The relationship between ameloblastomas and odontogenic epithelium remnants is crucial for understanding their development, behavior, and clinical management. Although other tissues, such as bone marrow, dental pulp, and salivary glands, are important components of oral biology, they are not the sources of ameloblastomas. Therefore, focusing on the origin of this tumor leads us to the correct identification of odontogenic epithelium remnants as its source.
