Sclerotic Dentin
This is a ground section through a tooth with a carious lesion. The carious dentin lies near the center of the field (A) with its free surface exposed. Close to the this dentin, between it and the pulp, is a homogeneous appearing "white" zone called sclerotic or trans- parent dentin (B). Sclerotic dentin contains dentinal tubules that have become completely obliterated by the deposition of peritubular dentin. This reaction by irritated odontoblasts forms a protective wall between themselves and noxious stimuli. Identify the remaining structures indicated on the image.
