Fluoride Action Network


This paper presents X-ray manifestations of industrial fluorosis in 100 cases. It is recognized that increasing density, bony structure changes and periosseous hyperplasia with calcification or ossification, especially the process of hyperplastic calcification of the posterior margin of tibia and interosseous membrane of radius and ulna, constitute the main criteria for the diagnosis of this clinical entity. Often all the above-mentioned processes make their appearance in the early stage of the disease but they may be delayed until the later stages. Preliminary analysis of the causes of this manifestation and classification of the stages of this disease with its various types are herein discussed.
