HOUGHTON HOLLIDAY A.B.. D.D.S. Associate Dean and Professor of Dentistry HA-ROLD J. LEONARD A.B., D.D.S. Professor of Dentistry Radiology Periodontia MILITARY ROENTGENOLOGY It is possible to seek and to find opportunities for constructive operations even during a war. We are indebted to the last war for our present compact, rugged, and dependable x-ray appa- ratus. The necessity for a type of equipment which could be readily transported, easily as- sembled, and kept in operating conditions of field and ship, resulted in the production of x-ray machines vastly superior to any in use before the war. Deplorable as war is, it need not be a total loss if its demands result in the discovery of better means of serving construc- tive ends. HOUGHTON HOLLIDAY It is the function of the Division of Perio- dontology to teach methods by which diseases of the investing and supporting structures may be recognized, the causes of such diseases elimi- nated, and diseased tissues brought back into health. This includes thorough diagnostic train- ing and habit, skillful instrumentation in treat- ing root surfaces, ability to teach patients tech- nics for keeping the teeth clean and the gingivae in vigorous tone, and great mechanical ability in reconstructive and replacement procedures.

HENRY U. BARBER, Jr. D.D.S. Assistant Prof, of Dentistry EDWARD G. MURPHY D.D.S. Assistant Prof, of Dentistry The Division of Orthodontics in its relation- ship vith the undergraduate may be said to have a hvo-fold purpose. Primarily, its object is to teach to the dental student those orthodontic factors which should be included not only in his knowledge but in the exercise of his general practice. Heading these factors is the capability of early recognition in children ' s mouths of tendencies toward mal- occlusion, and thus die prevention of these ab- normalities. This responsibility to his patients lies in the hands of the general practitioner. In order to prepare him, the department provides lectures on foundational factors and theoretics, and seminar sessions of observation of clinical patients under treatment, with emphasis on pre- vention of the existing mal-condition. Secondarily, the object is to acquaint die stu- dent with the basal technics of orthodontics and to let him test his abilitv ' . which might perhaps GEORGE S. CALLOWAY D.D.S. Assoc, Prof, of Dentistry LEUMAN M. WAUGH, D.D.S. Professor of Dentistry Orthodontics arouse his interest and shoW ' his inclinations toward graduate study with a view to specializa- tion. For this, laboratory sessions are provided with technical demonstrations of fabricating simple appliances. These in turn are made by the students, and standard requirements must be fulfilled.

CHARLES F. BODECKER D.D.S. Professor of Dentistry MOSES DIAMOND D.D.S. Assoc. Prof, of Dentistry Oral Histology Oral Anatomy The keynote of research in this Division is to determine whether the dental pulp exerts any physiological effects on the dentin and enamel of the teeth. This subject is an almost virgin field because the calcified dental tissues are con- sidered generally to be non-vital. Ample evi- dence, however, has already shown that a secre- tion of the pulp reaches the dentin and enamel for some time after the eruption of the teeth. Our working hypothesis is that this fluid, the dental lymph, is a major factor in dental caries, a disease which is so prevalent in children and adolescents. CH. RLES F. BODECKER The most important advance in education is the inclusion of research activity in any teaching program. This is an important departure from the purely didactic method of teaching which necessarily must function on the basis that knowl- edge is static. Knowledge is, instead, constantly in a state of flux, and it is disastrous to the pur- poses of education to adhere literally to any text, no matter how recent. Research is a means of . ' teadily adding to our knowledge, and serves as an indispensable medium to teaching. MOSES DI- MOND WILLIA.M LEFKOWITZ D.D.S. Assistant Prof, of Dentistry - ' ? ED.Ml .
