external definition
A structure that is involved in tooth formation. A bell shape two layer epithelial structure that descends toward the ceratobranchial 5 bone, enclosing the dental mesenchyme. At later times in tooth development the cells at the apex of the bell may be involved in enameloid formation. This structure remains at the base of the erupted tooth and is the source of replacement teeth.[TAO]

terminology notes
Historically, enamel organ has been the term to describe this structure, but it was attempted unsuccessfully in recent years to change the name to dental organ in order to better represent its multiple functions apart from enamel formation
