| Abstract: | Applying a complex of modern microangiological techniques, the organization of the blood bed in the incisor and molar pulp has been studied in the white rat mandible. Production of the dental tissue components in the zones of dentinogenesis is ensured by an increased density of the capillary and venular bed of the pulp, a tight connection of the capillaries with predentin. The morphometric data obtained make it possible to prognosticate a high intracapillary pressure and the hydratation degree of the interstitial gel in the incisor pulp, which is close to maximal figures. Differences in angio-architectonics of the incisor pulp and the molar pulp depend on the peculiarities of the histostructure and functional state of the pulp, on the geometry of the dental cavity and the radicular canals. The pulp blood bed possesses a complex apparatus that ensures the blood stream regulation (duplication of the nutrition sources, arteriolar and venular area, various types of anastomoses, precapillary sphincters and others). |
