Odontoblast Process Branching
This is a ground section. Rather than processing the tissue through fluids to section it with a micro-tome knife, the tooth is simply dried and ground to a very thin disc through which light is passed. Ground sections do not demon-strate well-preserved cellular detail but do have an important role in demonstrating empty spaces in the tissue. In this ground section note the branching ends (A) of the odontoblastic processes (D) seen here in the mantle dentin just under the dentinoenamel junction (B). Terminal branching of odontoblast processes is especially profuse in root dentin.
