Dental papilla

The dental papilla is a condensation of ectomesenchymal cells seen in histologic sections of a developing tooth. It lies below a cellular aggregation known as the enamel organ. The dental papilla gives rise to the dentin and 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.
