Thirty-nine teeth on eleven patients were treated. Thirteen of the teeth served as controls. The control teeth were treated in the same manner as the experimental teeth except that they were not ionized. Sixteen per cent 4 of the 26 experimental teeth responded with desensitization. Four per cent 1 exhibited immediatecomplete desensitization. Recovery of sensitivity was also noted in 8 2 teeth with immediatecomplete desensitization. No desensitization was observed in 84 22 of the teeth treated. General observations made on the teeth within this category showed that 1 teeth that were more difficult to prepare harder enamel and dentin had higher electrical resistances than those which were easily prepared and 2 patients that spent their childhood in areas having naturally occurring fluorides in the water supply had higher electrical resistances in their teeth than those patients who spent their childhood in areas that lacked natural fluoridation.
