[Interruption of the vegetative innervation of the teeth of dogs and its effect on the organs of chewing (author's transl)].
The results of our investigations, therefore, demonstrate that after a resection of part of N. vagosympathicus peripheral to the ganglion nodosum on the right side two of the test dogs showed changes in the bite and in the position of teeth, a fan-shaped position of the incisors and canines, prognathism of the jaw including protrusion and changes in the parodont with some incisors becoming loose. All test animals showed distinctly marked dystrophic changes and weak signs of regeneration of Truncus vagosympathicus and the branches of N. trigeminus. The changes in the branches of N. trigeminus can be explained by the intrusion of sympathicus cells in the reflex arcs of the cerebral nerves and in their paths in the central nervous system. In this way the sensory nerves are joined to the afferent fibres of the vegetative nervous system, which affect the organic supply through the vasomotor nerves.
