ORTHODONTIA LEUMAN M. WAUGH, D.D.S. Professor of Dentistry HENRY U. BARBER. Jr. D.D.S. Instructor in Dentistry EDWARD G. MURPHY, ARTHUR C. TOTTEN. D.D.S. D.D.S. Instructor in Dentistry Instructor in Dentistry The course in orthodontia consists of lectures, laboratory instruction, and clinical demonstrations. The lectures, which are delivered by Dr. Waugh, cover the fundamentals of orthodontics. No attempt is made to fit the student for the practice of orthodontia as a specialty. The purpose is rather to make clear the many useful services which the dentist can render his patients by early recognition of the factors which will influence existing malocclusion or tend to exaggerate this condition in the future. In the laboratory, the student constructs several types of appliances. The result of these procedures is to impart to the student a knowledge of the mechanical principles by which orthodontists accomplished desired corrections. Uses as well as abuses of the appliances are pointed out by Dr. Barber and his staff. The third part of this interesting course consists of clinical demonstrations. During these weekly sessions the student is permitted to observe the progress of orthodontic treatment on clinic patients. A. S. FRANK E. RIANS, D.D.S. Instructor in Dentistry HARRY GALTON, D.D.S.

ORAL DIAGNOSIS HAROLD J. LEONARD, JOSEPH O. FOURNIER. A.B., D.D.S. D.D.S. Professor of Dentistry Asst. Prof, of Dentistry LEWIS R. STOWE, D.D.S. Asst. Prof, of Dentistry While the term technique is not ordinarily associated with the field of Oral Diagnosis, there is nevertheless a form generally used in the execution of this branch of dentistry. This form has to do mainly with an orderly marshaling of facts learned in numerous departments and applying them to the solution of the problem as it arises. The student is taught the routine of mouth examination, and the identifying signs and symptoms of disease. But that is not enough. He must learn to reach out with mental facility and produce as many logical factors for analysis as the situation may seem to warrant. Thus the chief objectives in Oral Diagnosis instruction are to train the student in methodical thinking, in the ability to make deductions, and in the none too easy art of truly seeing the thing at which he is looking. Given proficiency in all these matters, he should be able to coordinate the theoretical and practical knowledge gained in this and other courses of study in such a way as to serve him best in making intelligent decisions for treatment planning when he is ready to launch forth on his own.

CHAS. F. BODECKER, D.D.S. Professor of Dentistry EDMUND APPLEBAUM, D.D.S. Asst. Prof, of Dentistry WILLIAM LEFKOWITZ, D.D.S. Assistant in Dentistry ORAL ANATOMY Oral Anatomy may be described as the first contact the dental student has with dentistry. Crowded as it is, amidst a lull freshman year of the basic medical sciences, its import as an applied science is not readily appreciated by the student and at the beginning of the course, one hears rather in- sistently the query, whether audibly or inaudibly, what is all this for? Every pure science has its reflected aspect in applied science. All knowledge is made definite use of in varying degrees, and the study of oral anatomy is applied in a very high degree to the profession of Dentistry. It is also true that the teaching of the morphology of the human tooth is not an easy problem. Variation in morphologic contour of human teeth as in all other life phases, is so vast, that copying an individual tooth cannot begm to give the student any real idea of the problem. For that reason, after a careful study of large numbers of teeth, it was found that a common denominator in mor- phological contour could be determined by stripping the variations. It must be emphasized that the common denomin- r ° ! ymme i nCal t0 ° th form does not present an IDEAL FORM but a BASIC FORM, which by slight modifications may be varied or individualized. M. Diamond. ORAL HISTOLOGY A knowledge of oral histology is useful as a practice builder. The preparation of a cavity for a filling is never an agree- able experience; young persons often suffer keenly during such operations. Dong clinical experience has shown that the treatment of a patient is more simple and less disagreeable when he has confidence in the operator than when he lacks it. A knowledge of oral histology imparts to the practitioner the ability to foretell pain, in this manner gaining the confi- dence of the patient. Some other practical applications of Oral Histology can be mentioned. The necessity of knowing the structure of the enamel in cavity preparation; the differ- ences in teeth of young and old persons resulting in their varying sensitivity; the nutritive organs of the dentin and cementum and many other facts concerning the dental tissues. The course gives the operator the necessary conception of the minute structure of the teeth and makes clinical work more interesting. Finally it aids in training dentists who, if they are careful and conscientious, will gain the confidence of their patients. Charles F. Bodecker. MOSES DIAMOND. D.D.S. Assoc.
