[Vasomotor innervation of the maxillary canines of the dog].
Maxillary canine pulpar pressure was recorded on anesthetized dogs by means of a small bore cannula threaded into a hole drilled through the lateral surface of the tooth. Vasoconstriction was brought by the electrical stimulation of the cranial cervical ganglion. Vasodilation was induced by stilmulation of the pterygo-palatine ganglion. This vasodilation was inhibited by atropine. Most often, constrictor fibres follow the course of the pterygo-palatine nerve, when dilator fibres follow the infraorbital nerve. However, both sorts of fibres may be found in the infraorbital nerve.
