No, they are transient cells that undergo apoptosis (cell death) once enamel formation is complete, so they are not found in mature teeth.

No, it is a highly technical term used only in specific scientific and medical fields like dentistry and embryology.

They are adjacent cell types working together during tooth development. Odontoblasts form the dentin layer, while ameloblasts form the enamel layer that covers it.
