Abstract: | Aim: To determine the role of damage to the ultrastructural elements of the periodontal nervous system in the pathogenesis of dystrophic periodontal disease. Materials and Methods: The basis of the experimental part of the study was the preparation of ultrathin sections from blocks of gum tissue of white rats, which were prepared using the UMTP-3M device. The study and analysis of biopsy samples was carried out with the help of an electron microscope UEMV-100K. Results: With the help of transmission electron microscopy, it was found that from the first minutes after the injection of hemolysate of isogenic erythrocytes into the rats, aggregates of erythrocytes, clumps of blood plasma, clusters of fibrin monomer masses, bundles of fibrin fibers, platelet and homogeneous were present in the connective tissue of the gums, and in particular in the lumens of hemocapillaries microthrombi, which confirms damage to the ultrastructures of the periodontium, which lead to the development of a pathological process, which is described when simple coagulation dystrophy is reproduced. Conclusions: Coagulative damage to the ultrastructural elements of the periodontal nervous system is one of the important factors in the pathogenesis of dystrophic periodontal damage. Under these conditions, trophic disturbances occur, similar to those that occur when the integrity of the nerve is disturbed – neurotrophic mechanism of dystrophy. |
