LINDSAY, LILIAN : Library, British Dental Association, London, England (June 3, 1938).


From clinical experience for over a quarter of a century, the author con­cludes that the three enemies to health are overindulgence, idleness, and fatigue, in all of which diet plays a great part. When the body is in perfect health, all reflexes and reactions of the tissues are in a tonic state and do not tolerate any foreign matter. This is a condition of great importance in the mouth because, when there is any deterioration, the self-cleansing apparatus is not in order and carbohydrate foods, sticking and fermenting, cause caries and periodontal disease. The structure of a tooth may help to prevent caries, but it is quite ineffective when sufficient debris lodges; then fermentation ensues, enamel is disintegrated, and the tooth destroyed. The best and most completely calcified tooth is the most readily attacked by fermentation acids on account of its greater inorganic content.
