Correction of metabolic changes in the tissues of oral cavity of rats using a complex of drugs under the conditions of pathological factors
Keywords:intrauterine tissue hypoxia, cariogenic diet, caries-prophylactic effect, plant polyphenols, rats
Hypoxia is a typical pathological process that occurs when tissues are insufficiently supplied with oxygen or when its utilization is impaired. One of the most important pathogenetic factors in the development of tissue hypoxia is the disintegration of the structure of mitochondrial membranes which occurs under the influence of various etiological factors. In children who suffered hypoxia in the antenatal period, the frequency of developmental delays is significantly increased, and the incidence of caries is also shown to increase as compared to healthy children. Based on the above, this work is relevant for modern dentistry. The work is devoted to the study of the state of the maxillofacial system and tissues of the oral cavity of rats under the influence of the complex of drugs under the conditions of intrauterine hypoxia, cariogenic diet, thyroid insufficiency and fluorine deficiency. The subjects of the study were 25 female white rats of the Wistar line of herd breeding from the vivarium of the SE “ISMFS NAMS” kept on a standard vivarium diet. The animals were divided into three groups – intact (7 rats), pathology model (8 rats), pathology model and drug complex (8 rats). Animals were removed from the experiment under thiopental anesthesia (40 mg/kg). Lower jaws and pulp were removed. As a result of the research, it was established that the proposed treatment-prophylactic complex has a pronounced caries-prophylactic and periodontoprotective effect. The caries-preventive effectiveness of the complex was due to its ability to stimulate the mineralizing function of the dental pulp, namely, to increase the activity of alkaline phosphatase of the pulp, as an indicator of the activation of osteoblasts, against the background of a decrease in the activity of acid phosphatase, a marker of osteoclasts.
