scientists who pioneered in the study of fluorides and their effect on teeth.”
Dr. Stewart’s statement continued: “Today fluoridation has taken its place next to chlorination, pasteurization and immunization as one of the four horsemen of public health as a result of the experimental and epidemiological studies conducted by this group.
”These studies established that the addition of one part of fluoride to a million parts of water would reduce tooth decay with complete safety.
The contributions of these men will be long remembered.”
