Radicular Pulp
This is a section through the apical end of a developing root, exhibiting radicular pulp (A). Odontoblasts (B) form the outermost component of the pulp, after differentiating from the mesenchymal cells of the dental papilla. The odontoblast cell bodies are in the pulp chamber but their processes extend up into the overlying layer of dentin (C). Note the strand of epithelial tissue lying between the root and the upper margin of the field (D). This is the epithelial root sheath. Its eventual breakdown will allow cementum to form over the surface of the dentin.
