Secretion of Predentin
As the odontoblasts (A) continue to differentiate on the periphery of the dental papilla (B), they begin to secrete a product between themselves and overlying cells of the IDE. This product is predentin (C). Predentin is converted to dentin by mineralization. The central region of a bell stage tooth germ is in the center of the field. You should be able to identify: IDE (D), ODE (E), stellate reticulum (F), and stratum intermedium (G).
