A double blind test for determination of intolerance to fluoridated water (preliminary report).
Abstract
A double blind test for the detection of untoward effects from fluoridated water is described. Preliminary results with 60 patients out of a group of 300 indicate that certain individuals are intolerant to fluoride and reproducibly develop gastrointestinal symptoms, stomatitis, joint pains, polydipsia, headaches, and visual disturbances.
