Abstract
Recordings were made on the neural responses evoked by stimulation of dentin with solutions of NaCl, NH4Cl and dextrose. Stimulation of the outer dentin produced no response. From the inner dentin, a smaller number of impulses were recorded with solutions of NaCl than with corresponding concentrations of NH4Cl, but a much larger number than with solutions of dextrose. The discharge evoked by a solution increased in mean frequency and decreased in latency as the thickness of dentin was reduced. The receptors were in the innermost dentin or the pulp, and they were excited by changes in extracellular fluid composition rather than by osmotic effects. The properties of the receptors appear to be different from those involved in pain from dentin in man.This publication has 6 references indexed in Scilit:
