Chapter I discusses fluor in connection with its bioenic properties. It is one of the biogenic elements whose traces we find in most living creatures. The part fluor plays in the prevention of dental caries is well known. The article sets forth the alfinity of fluor with genetic tooth tissue and in this connection it is stressed that fluor does not exerce its action on milk-teeth and teeth ill old age. Many instances are given to illustrate the importance of fluor in the prophylaxis of dental caries through fluorization of drinking water. Chapter II deals with acute and chronic fluor poisoning of men, animals and plants. Clinical observations were confirmed by animal tests. Chapter Ill puts forward the importance of fluor in professional pathology. Changes caused by fluor were first observed in 1932 as osteosclerosis (fluorosis) in workers engaged in the production of criolite. Since then many findings all over the world have confirmed the noxiousness of fluor. Occupational fluorosis appearing in most cases as an affection of bones shows, in the first stage, irregularities in bone formation: the bony trabeculac in the spongy substance arc thickened causing blurred contours in X-ray pictures. In the second stage the thickening of the trabeculae progresses and partly unclear, homogeneous shades can be seen. There appear periosteal layers and growths. The connecting parts of tendons are calcified. The bony substance of hollow bones thickens and the medullary cavities narrow down. In the third stage the bone structure is hardly distinguishably. Eburnation set, in. accompanied by periosteal growths and progressive calcification of the connecting tissues of tendons and ligaments. All these changes are particularly apparent in the pelvis and in the lumbal part of the vertebral column. A good prophylactic measure is a change of working place after five years of work in an exposed position and X-ray examinations every three years. The author mentions the American regulations concerning the maximal concentrations of fluor dust in workshops (0.2-0.3 mg/m3 air), Close collaboration of hygienists. health workers, labour inspectors and technical experts is commendable in order to organize protection from Fluor poisonings. In most countries damages caused by fluor rank among occupational diseases entailing a right to compensation.
