Dental Pulp and Central Pulp Cavity Pulp Chamber

The dental pulp cavity is a connective tissue compartment bounded by the tooth dentin

The central pulp cavity is the space within a tooth that is occupied by dental pulp, a loose connective tissue that is richly vascularized and supplied by abundant nerves. The pulp cavity takes the general shape of the tooth. The blood vessels and nerves enter the pulp cavity at the tip (apex) of the root, at a site called the apical foramen. (The designations apex and apical in this context refer only to the narrowed tip of the root of the tooth rather than to a luminal (apical) surface, as used in describing secretory and absorptive epithelia.)

The blood vessels and nerves extend to the crown of the tooth where they form vascular and neural networks beneath and within the layer of odontoblasts. Some bare nerve fibers also enter the proximal portions of the denti-
