In a group of 200 pregnant women, attending the Prenatal Clinic, Yale University School of Medicine, age, number of pregnancies, and economic status exercised little or no influence on teeth and gums; undernourished women showed increased caries and periodontal pathology ; and women who ate more green vegetables and less meat seemed to have better teeth during pregnancy.
All necessary dental work was carried out during pregnancy. The patients were instructed in mouth hygiene and in use of a balanced diet, with emphasis on milk and green vegetables.
