THE researches of Mrs. Mellanby on the part played by diet in the development of the teeth and jaws in animals have already been referred to in these columns.1 A report on the relationship between diet and the structure of human teeth is in course of preparation. Mrs. Mellanby's work has also led to the conclusion that it is possible to influence the structure, and thereby the resistance to disease, of teeth after eruption. It was obviously desirable that this conclusion should be confirmed by a large-scale clinical trial. A preliminary report of such a trial has now been issued by the Committee upon Dental Disease.2
