Sognnaes, Shaw Believe Dental Diet Could Prevent Future Tooth Decay

Two dental school professors, Dr. Reidar F. Sognnaes. Associate Dean of the School, and Dr. James H. Shaw have been studying tooth structure with radioactive phosphorous, and think dental dietary care is possible.

They injected phosphorous into the blood stream and applied it to the tooth surfaces of monkeys.

Speaking to the Mid-winter meeting of the Chicago Dental Society, the men asserted that their study of the changes in structure might inaugurate further experimentation on the causes of tooth decay. They added that, eventually the research might show what to put in a dental diet.

Dr. Sognnaes won the prize of the Norsk Tanvern in 1948 for distinguished Norsk Tanvern in 1948 for distinguished decay resulting from Northern Europe's World War II food rations.
