The Staining of Nerve Fibers in Teeth

Abstract

The use of the Romanes and the Ungewitter silver nitrate technics as necessarily modified for the demonstration of nerve fibers in the pulp and the dentin of adult human and matured rat teeth is discussed. In spite of numerous statements to the contrary it was possible to demonstrate that there are nerve fibers in the dentin and that in their course through this hard tissue the fibers present many varicosities and that they may terminate in so-called nerve endings.
