ResumoThree anatomic techniques were used to study the transmedian innervation of the canine teeth of felines. They were (i) the Fink-Heimer II staining technique for degenerating axons, (ii) the cobalt, cut-axon technique, and (iii) the examination of retrograde chromatolysis in trigeminal ganglion cells following tooth pulp extractions. It was clearly demonstrated, using all three techniques, that canine teeth receive an extensive transmedian innervation, although the ipsilateral innervation exceeds the transmedian innervation. Approximately 199 trigeminal ganglion cells project to an ipsilateral canine tooth, whereas approximately 138 cells project to a contralateral canine tooth. These figures represent 0.5 and 0.3% of the cells in the trigeminal ganglion, respectively.
