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 .

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.

Pedodontia EWING C. McBEATH D.D.S.. B.S.. B.M., M.D. Professor of Dentistry Current revolutionary and economic changes have imbued the teaching institution with its new and varied obligations to the student. The prep- aration of entrants into the fields of medicine and dentistry must equip them to anticipate and to recognize public health needs and to meet them by exercise of professional judgment and initia- tive expeditiously and intelligently. This de- mands a more thorough familiarization with and timely construction of the fundamental sciences for facile interpretation and application. I know of no more fitting place in dentistry for the discerning utilization of this basic knowl- edge than in the practice of dentistry for chil- dren. Proper care of the child patient demands a ready availability and appropriate employment of the many and varied details of this broad source of knowledge. e. c. mc beath Oral Pathology o LEWIS R. STOWE D.D.S. Assoc. Prof, of Dentistry SOLOMON N. ROSENSTEIN B.S.. D.D.S. Assistant Prof, of Dentistry LESTER R. CAHN D.D.S. Assoc. Prof, of Dentistry Besides the teaching of the subject, the divi- sion of Oral Pathology has been concerned in the investigation of many problems of clinical importance. The result of oral infection by the herpes simplex virus has been studied for some time now, and a paper on the subject is now in press. An investigation into methods of sterilization of instruments and material has enabled the evalu- ation of a number of such methods which should simplify the choice of procedure for this impor- tant process. A filamentous organism removed from dental stain has been grown in - pure culture as a fun- gus. Bone diseases have been investigated from a clinico-patho- logical standpoint, and the role of epithelium in bone formation is also under considera- tion. LESTER R. C. HN HENRY A. BARTELS B.S..
