The recent researches of Smith, Lantz, and Smith (1), Churchill (2), McKay (3), Kehr (4), Ostrem, Nelson, Greenwood and Wilhelm (5), Boissevain (6), Dean (7), Sebrell, Dean, Elvove and Breaux (8) and Boruff and Abbott (9) have contributed greatly to our knowledge of the distribution of fluorine in drinking waters and the effect of such waters in the production of mottled enamel of the teeth. Smith, Lantz, and Smith (1), of the University of Arizona, were the first to show that this tooth defect is due to fluorides in the drinking water; they have analyzed the fluoride concentration of waters in endemic areas and have reported it to be high. Dr. H. T. Dean (7), of the United States Public Health Service, has made a recent survey of the occurrence of mottled enamel in the United States and reports that this condition is known to occur in twenty-two states. It is found in other countries also, notably China, Japan, Africa, Italy, Holland, Argentina, Mexico, and England.
