A panoramic radiograph shows a lesion that turns out to be an adenomatoid odontogenic tumor (AOT). What is the origin of this lesion?

The adenomatoid odontogenic tumor is classified as a benign, developmental odontogenic lesion (sometimes described as hamartomatous in nature) arising from odontogenic epithelium — it is not infectious in origin, and despite being called a 'tumor,' it behaves in a benign, well-circumscribed, slow-growing developmental manner rather than as an aggressively malignant neoplasm.
