Elektrovozoremontnij teeth in dental caries

Studying symmetrical teeth in dental caries, A. P. Panina (1968) examined 3,000 people aged 15 to 60 years. Taking into account the teeth affected by caries and its complications, teeth removed for complications of caries, teeth, covered with a single artificial crowns. Was not considered teeth removed about periodontal disease, teeth, used as a reference under bridges, and wisdom teeth.
The survey showed that the horizontal symmetrical caries considerably prevails over the vertically symmetric. So, for example, horizontal symmetrical Central incisors in women is 51%, and vertically symmetric - 0,3%, in men horizontally-symmetrical is 50%, and vertically symmetric - 1,4 %. The same approximate ratio occurred in the study of other teeth. Received by this author the data left no doubt that vertically symmetrical is purely accidental, caused by multiple lesions of teeth caries, while horizontally-symmetrical - the natural phenomenon, very often observed in most people. Imagine this phenomenon without the participation of the Central nervous system is impossible.
Conducted by A. D. Jafarova (1968) studies teeth in children during the formation of roots showed that elektrovozoremontnij in fissures, decayed, higher than in intact fissures.
Changes pulp with dental caries have been studied by many authors. Exploring morphologic? pulp when caries, E. M. Prikazchikova (1926) found that "with deep caries normal state of the pulp is not observed. Notes often round-cell infiltration. Proliferat consists of a round of lymphoid elements with the presence of plasma cells and a small number of cells. Picture of hyperemia and round-cell infiltration is observed not only according to the lesion under a layer of odontoblasts, but in the deeper lying areas pulp".
However, not only deep, but with an average caries in the pulp in a number of cases, are determined pronounced inflammation.
At surface caries were awarded the same changes, but only less pronounced. "The number of odontoblasts in almost all cases been reduced, layer them vacuolation; much more pronounced destructive changes. Cell shrinks, acquired an irregular shape, extensions of their shortened, appeared kernel with scalloped edges, with chromatin, located on the periphery of the core with a large gubkami. In the cytoplasm of some of the cells were marked with small droplets of fat. Compared with the first group (caries as spots) was significantly less priodatabase. It was noted depletion pulp cellular elements, edema, swelling of the vascular endothelium, the appearance of small perivascular infiltrates, which consisted of lymphoid elements of plasma cells" (I.e. Century Alexandrov, 1965).
Further work in this direction has shown that the decay even in the stage spots in dental tissues occurs a number of changes: in the dentin is determined transparent layer, and in the pulp - crowded conditions, and puckering of odontoblasts and change their tinctorial properties. These changes in odontoblast caused, in the opinion of some authors, toxic products that fall into the dentin in the pathologically increased permeability enamel caries. When surface caries observed decrease series of odontoblasts, redness and swelling of the pulp.
Greater attention should be paid observations S. S. Weill (1949), who showed that with the transition of the pathological process on the dentin and deprivation of the dentinal tubules their enamel cover vessels root pulp are filled with blood and through their walls starts sweating serous fluid. Often there are and minor bleeding. To sweaty fluid added soon and shaped elements, mainly leukocytes. Sometimes there are larger aggregations of cells in the form of small abscesses.
