The conditions of this study (treatment of a fairly large number of children; examinations before and after treatment by the same dentist; no knowledge of the treated quadrants at the time of the concluding dental examinations; and applications of the drugs by a competent group of dentists familiar with the technic) indicate that zinc chloride and potassium ferrocyanide are not effective in controlling the incidence of new caries. The claims for the prophylactic effect of the so-called impregnation technic are, therefore, not supported.
