[The role of fluorides in the prevention of dental caries].
By searching for the cause of mottled enamel--which was known already in Italy of the Roman period--the researchers Churchill, Smith, Lantz and Velu were almost simultaneously led to the recognition that the surplus fluoride in drinking water is the cause of the phenomenon. Thereafter, by Dean and his collaborators it was proved by means of mass caries screenings and chemical analyses of drinking water that if the drinking water contains 1 mg F-ion by litre then there is no mottle on the enamel while the condition of the teeth is substantially by about 50 to 60% better than those of consumers of drinking water poor in fluorine. The safely tolerable dose is 1.5 to 2.0 mg by litre. Obviously this is a populational resume drinking water which is natural or artificially enriched with fluoride. Employment of the fluorides has considerably been extended in the course of research and development. The methods can be grouped in several manners. In the author's opinion the best grouping is: a) collective and b) individual methods. The element F belongs to the group of the + type poisoning elements which, however, does not occur in nature because when getting into nature it immediately combines with ther elements and, therefore, in nature only its various salts are met with. Chronical fluorosis is caused by consuming 5 to 10 mg fluoride through many years. 100 to 200 mg is a lightly poisoning dose with children or adults. A mortal dose is 1200 to 2500 mg.
