FLUORINE AND FLUOROSIS
Sir,
With regard to your remark 'This has led to the suggestion that non-toxic amounts of sodium fluoride. may be added to drinking water for the prevention of dental decay' in the editorial of June number 1944, I wish to draw your attention to the fact that the use of fluorine in dental treatment is in vogue already. A good account was published by Prof. E. H. Lukmsky, Director, Stomatological Clinic, First Moscow State Medical Institute (fluorine cu
Therapeutics and Pharmacy.
CALCIUM FLUORIDE
The therapeutic uses of the fluorides have received comparatively little attention, notwithstanding the fact that it is now generally recognised that a certain amount of fluorine in the form of calcium fluoride is a necessity for the proper strengthening and consistence of the bones and for the normal hardness and good condition of the teeth. According to the Pharmaceutical Journal, however, at least two observers have successfully employed calcium f

A PERFECT antiseptic for surgical purposes has yet to be found. It must be at the same time a strong germicide, non-poisonous, unirritating to the skin or to the tissues, inodorous, non-volatile, not destroyed by oxidation, non-corrosive to steel instruments, non-injurious to sponges, and inexpensive. In " salufer " (silicofluoride of sodium) we hav
FOR some 8 or 9 years past the presence of fluorine in water supplies has been attracting much attention, chiefly as a danger and as the cause of endemic dental fluorosis, or mottled enamel, which has been reported in some 300 communities in 23 states of the Union.
According to Dean,1 this condition was first described by J. M. Eager 2 in a report from Naples under the name " Denti di Chiaie (Chiaie teeth)," so called from Dr. Stephano Chiaie, who first observed the condition in Italy, where
About the month of April 1936 the district health officer, Nellore, Dr. Lakshminarayana, had his attention drawn by the health inspectors of Podili and Darsi ranges of the Nellore district to a disease characterized by a definite train of symptoms and which was very prevalent in the district. The most obvious symptoms of this disease were stiffness and pain in the spinal region and in various joints. Cattle were stated to be similarly affected. In August 1936, the district health offic

THE endemic hypoplasia of the permanent teeth known in this country as mottled enamel was first reported by Eager in 1901. The first investigation in the United States was the extensive one of Black,2 and McKay,3 published in 1916. At present in this country alone there are more than 200 areas where endemic mottled enamel has been confirmed by survey; in addition there are approximately 100 areas where the endemicity has been reported but not confirmed by survey. These approximate 300 a

HUMAN EVIDENCE
NTP based its conclusion in the monograph primarily on human evidence. NTP considered the human evidence to be “relatively robust” and evaluated the association of fluoride exposure and neurodevelopmental and cognitive effects as reported in 82 publications. Although it evalu

It has been generally accepted that a concentration of 1 per cent sodium fluoride is adequate to prevent glycolysis in nonprecipitated blood and that no appreciable glycolysis results if the blood proteins are precipitated within 5 minutes after the blood is drawn (1). Determinations of lactic acid in the blood precipitated within 5 minutes or preserved in 1 per cent sodium fluoride have yielded a range of 8 to 20 mg. per cent for normal subjects under basal conditions.
