Особенности структурной перестройки компонентов пародонтального комплекса на раннем этапе развития экспериментального бактериально-иммунного пародонтита

Аннотация

The inflammatory process in the periodontium is the most widespread among dental diseases, that is characterized by a recurrent course and significantly reduces the quality of life patients. Existing data about structural and pathomorphological changes in the tissues of the periodontal complex for the of inflammation development does not explain largely the patterns of the destructive phenomena development in this pathology. and therefore require additional research. The purpose of this study was to determine the peculiarities of struc- tural components of periodontal complex and their changes on the 7 th day of the experimental bacterial- immune periodontitis development. In the study of intact animals, it was found that connective tissue of its own plate is represented by collagen fibers, forms high connective tissue papillae and closely adheres to the epithe- lium. The histological study showed that on the 7th day of the experimental bacterial-immune periodontitis de- velopment of typical and spread inflammatory reaction onto all periodontium was observed. However, the se-verity of this reaction was different in the structural components of the periodontium. Fibroblasts were the most often found among cellular elements, less frequently – histiocytes, lymphocytes, single plasmacytes and mono-cytes. It was an increase of the fibroblasts number, that perform the resorptive functionof collagen fibers and reduce number of active osteoblasts. All these pathomorphological changes testified about of the inflammatory process development
