den·tal pa·pil·la

[TA]
a projection of the mesenchymal tissue of the developing jaw into the cup of the enamel organ; its outer layer becomes a layer of specialized columnar cells, the odontoblasts, that form the dentin of the tooth.
Synonym(s): papilla dentis [TA], dentinal papilla

dental papilla

Etymology: L, dens, tooth, papilla, nipple
a small mass of mesenchymal tissue in the enamel organ that differentiates into dentin and dental pulp during tooth development. The innermost layer consists of a cell-free zone of reticular fibers that form the basement membrane.

It is thought to occur during morphodifferentiation stage as a result of outward folding of inner enamel epithelial cells (precursors of ameloblasts) and transient focal hyperplasia of mesenchymal dental papilla (precursors of odontoblasts) or a combination of genetic and environmental factors (multifactorial) (2).
Dens invaginatus is a developmental malformation resulting from an invagination of enamel organ into the dental papilla, beginning at the crown and some- times extending into the root before calcification oc- curs.
5) Lowell and Soloman believe that fused teeth result from some physical action that causes the young tooth germs to come into contact, thus producing necrosis of the intervening tissue, thus allowing the enamel organ and Dental papilla to fuse together.
9) According to Covani et al the CODF was believed to originate from mesenchymal odontogenic tissue such as dental papilla, periodontal ligament, or dental follicle.
Dens Invaginatus (DI) is a dental anomaly which results from invagination of enamel organ into dental papilla, beginning at the crown and sometimes extending into the root before calcification.
Its expression is increased in cap stage in enamel knot, inner enamel epithelium and dental papilla whereas Msx2 expressed in odontoblasts, cuspal formation, root initiation.
