THE INFLUENCE OF AEROGENIC FACTORS ON THE DENTAL HEALTH OF MANGANESE LIMESTONE MINING WORKERS
The extraction of manganese limestone is carried out by mining the reserves of manganese limestones of the Ulu-Telyak deposit in two quarries: Severny and Novo-Severny, which are strategically important objects throughout the Russian Federation. The maximum productivity of quarries for manganese limestone is 1000 thousand tons per year. The impact of manganese on somatic health is presented in the literature quite widely, at the same time, the effect of manganese dioxide in the composition of limestone on the dental status of workers is practically not studied. Due to the high toxicity of manganese, it can be assumed that it has a negative effect on the blood supply to all organs and systems, including periodontal and oral mucosa. In the literature available, we failed to find such studies. This became the basis for studying the current problem. Purpose. To study the main indicators of the microcirculatory bed of the periodontium and the oral mucosa in workersunderthe influence of manganese limestone Materials and methods. Study of working conditions by chemical factor, dental examination, study of periodontal microcirculation. Results. Based on the study, it has been shown that the working conditions of workers for such a production factor as fibrogenic aerosols containing manganese dioxide (hazard class 2) are classified as harmful Class 3, hazard degree 1. Depending on the nosological form of the dental disease, workers of the main professions revealed significant disturbances in the microcirculation of the periodontium and oral mucosa,starting from a slight decrease in tissue perfusion with blood and vasomotor activity, ending with the defeat of the predominantly nutritious link in the microcirculation pathways and changes in blood flow in the venular section of the microcirculatory bed. A set of measures has been developed for the prevention of dental pathology, including organizational, technical and treatment and prophylactic measures. Conclusion. The working conditions of limestone workers according to the chemical factor represented by a fibrogenic aerosol containing manganese dioxide correspond to the 3rd class of the 1st degree of hazard. It has been proven that the toxic effect of manganese dioxide (hazard class 2)is one of the most important triggers for the development of microcirculatory changes in the mucosa and periodontium in workers, which requires further research to develop individual methods of prevention, depending on the nosological form of the dental disease and the class of working conditions of the worker.
