Vegetative innervation of the teeth

The question of vegetative innervation of the teeth and periodontal practically not been studied. In this respect otryvochnye information is not able to give us at least an approximate idea about the supply of teeth vegetative fibers. It is known that the transection of the cervical part of the border trunk calls a temporary extension of the vessels of the skin and mucous membranes of the oral cavity. In 1879 Jolli, Laffont showed that the second branch of the trigeminal nerve has vasodilator fiber: irritation of peripheral end cut maxillary nerve leads to the vasodilation and increased temperature in the area of innervation, in particular the mucous membrane of the upper lip, palate and gums on the corresponding side.
Many vegetative fibers, and in the third branch of the trigeminal nerve. To date, however, are not firmly established, where join the vegetative fiber to the trigeminal nerve - before or after the discharge of its branches from gussarova site. Some authors consider that the sympathetic fibers join the nerve after the discharge of its branches from gussarova site. However, it seems, is in respect of only some of the sympathetic fibers. Even less do we know about the parasympathetic innervation of teeth, while the trigeminal nerve is closely connected with the parasympathetic nervous system through five sites ciliary, pterygopalatine, ear, submandibular and sublingual.
