DENTAL DECAY
MEANS FOR PREVENTION AMERICAN EXPERIMENTS CHICAGO. Feb. 13. Dr Robert Kesel, of the University of Illinois Dental College announced that experiments with dibasic ammonium phosphate indicated ammonia as a means of preventing tooth decay. Ammonia apparently prevents the formation of enamel-destroying acids and kills decay-inducing bacteria. Dr Kesel said it would take two years to determine if by incorporating an ammonium compound in tooth pow,der and mouth rinses treatment would be permanently beneficial. He added that he hoped to discover methods of inducing the body to develop its own ammonia in the saliva.
