Membrane preformativa
The preformative membrane is an anatomical structure that occurs during tooth development . As a basement membrane, it forms the interface between the determined mesenchymal connective tissue ( mesodermal dental papilla ) and the ectodermal enamel organ . This basement membrane thickens shortly before the beginning of dentin formation and represents the dentin-enamel boundary during development. Here odontoblasts and amelo- or adamantoblasts lie back to back shortly before the onset of predentin / pre-enamelum formation and then move away, leaving them behind dental hard substances formed in opposite directions from each other.
