Clinical-radiological aspects of development of dental fluorosis

Abstract

There have been a clinical-roentgenological research of influence of chronicle fluorine intoxication on the change of periodontium structures which in conditions of hyperfluorosis have systemic character and predetermine certain clinical-roentgenological manifestations and development of pathological processes in periodontum. The research has been performed basing on clinical-roentgenological manifestations of fluorosis observed both in population of ecologically adverse regions and. in workers of plants and with the help of comparative analysis of the results received during the study. Analysis of the obtained data of clinical-roentgenological changes of periodontum. at chronic fluorine intoxication showed that in the first (control) group observed manifestations stayed within the limits of age changes in this region. In the second group pathological signs were marked during the second time period. (6—10 years), henceforth clinical picture of affected periodontium structures became aggravated. In workers of chemical production because of more intense accumulation of fluoric compounds in structures of periodontium clinical signs of it affection are displayed in the first and. avalanche-like grow in the second and the third time periods, whereas destructive-dystrophic changes in periodontium have more generalized and. irreversible character. The dynamics of revealed clinical-roentgenological manifestations happening in structures of periodontium shows that with the increase of time of residence on the territory and length of service on the manufacture, destructive-dystrophic processes in those structures become more extended.
