Innervation of dentine

The question of innervation dentin caused and continues to the present time be contentious. As you know, many authors (Riegele, 1934; Cocker, Hatton, 1955; Fearnhead, 1957; Hattyasy, 1959, and others) saw the nerves in the main substance of the dentin or dentinal tubules. However, many authors who hold diametrically opposite view and believe that found in the dentin nerve fibers artifacts. Special attention deserves the opinion of L. I. Falin's team, from the laboratory which turned out a lot of valuable works have made a great contribution to the Chapter on innervation dental tissues. According to L. I. Falin's team, nerve receptors are defined only in the pulp and predestine. In calcified dentine he nerve fibers were not observed and their presence there completely denied.
"Makoto nerve fiber - he writes, - says dichotomously two thin branches, each of which gives a number of terminal threads. They all go through a layer of odontoblasts and penetrate into presdentin, where they can be traced to the border of the layer calcified dentin. Thus, it is nerve ending, having the form of a Bush, provides innervation of predestine, although afferent fibers, which it is formed, began to ramify within subtotalling layer of pulp... in Addition to the above nerve endings in predestine there are still other, in respect of which it is difficult without appropriate experiment to say whether they are sensitive or efferent" (L. I. Falin, 1956).
Along with the described receptors in predestine often defined thin single nerve fibrils, which are dentinal tubules. They represent a terminal thread chastikovyh nerve endings located in pedodontists layer, and in principle do not differ from those receptors that have been described L. I. Fainym in 1968
