INFLUENCE OF ADVERSE ENVIRONMENTAL FACTORS ON THE EXAMPLE OF FLUORIDE COMPOUNDS ON THE PROCESSES OF PNEUMATIZATION OF THE FRONTAL SINUSES
The adverse effect of excess fluoride compounds on bone tissue has been known for a long time, however, there were no works devoted to the influence of chronic fluorine intoxication on the processes of pneumatization of airborne bones of the skull in available literary sources. The purpose of this research was to study the dynamics of age-related changes in the size of the frontal sinus and the nature of its pneumatization in an ecologically adverse region under the influence of fluoride compounds on the body. Morphometric examination of the frontal sinus has been performed, according to the radiographs of the skull in the nose-frontal plane of inhabitants of the ecologically adverse zone - the Nadvoitskii village, Segezhsky district, the Republic of Karelia. The control group consisted of inhabitants of Petrozavodsk. The received digital material was divided into age groups without regard to gender and was subjected to statistical processing. The following conclusions are drawn as a result of the research: 1) Fluoride compounds have an adverse effect on the pneumatization of the frontal sinuses; 2) Children as a result of impact to fluoride compounds observed a retard in the growth of the frontal sinuses, their pneumatization ends later, and the size does not reach the control group; 3) The effect of fluoride impact to the development of early osteosclerosis of the airborne bones of the skull in mature and old age, which leads to a reduction in pneumatization compared with the control group.
