The '''dental papilla''' is a condensation of [[ectomesenchymal]] [[cell (biology)|cells]] called [[odontoblast]]s, seen in [[histology|histologic]] sections of a [[tooth development|developing tooth]]. It lies below a cellular aggregation known as the [[enamel organ]]. The dental papilla appears after 8-10 weeks intra uteral life. The dental papilla gives rise to the [[dentin]] and [[Pulp (tooth)|pulp]] of a [[tooth]].
The enamel organ, dental papilla, and [[dental follicle]] together forms one unit, called the ''tooth germ''. This is of importance because all the tissues of a tooth and its supporting structures form from these distinct cellular aggregations.
