ABSTRACT:
A fluoride supplement calculator utilizes two concentrically positioned relatively rotatable disks. A front disk has a plurality of fluoride level apertures which overlie groups of fluoride dosage amounts carried on the second disk. An age scale is also placed on the obverse surface of the second disk. The second disk has a single aperture which is used in conjunction with the reverse surface of the first disk to depict fluoride uptake and enamel formation in teeth of patients of various ages.
