Prosthetic Dentistry The end of the 19th century saw dentistry as a young profession concerned primarily with the tooth and its surrounding tissue as an entity. Prosthetic dentistry was engrossed with the tech- nology of restoring or replacing missing teeth. (Development of materials, instruments, and methods was paramount.) Plaster of paris, vul- canite, wrought metals, and solder were the vehicles for prosthesis. The articulator was in its infancy; investigation of the function of masti- cation and mandibular movement was just begin- ning. With the turn of the century technological approach was modified by the realization that all sciences have much to contribute to dental investigation. The relation between dental and oral infection and svstemic conditions was of in- creasing concern and resulted in marked changes in prosthetic procedures. Asepsis, hygiene, and biologic compatibility became prime considera- tions in prosthetic design. Crown and bridge retention by the dowel crown was replaced by the coronal retainers on vital teeth. The casting process was introduced to dentistry in 1907 by Taggart and resulted in a vast technological change in prosthetic den- tistry. The development of hydrocolloids and alginates as impression materials has led to an accuracy that was unattainable previously. In the removable partial denture field the swaged base, wrought wire clasp, solder assem- bled denture was in wide use at the beginning of this period. Nesbit with his cast removable bridge was the forerunner of a wide acceptance of the one-piece, cast, removable partial denture. Full dentures have been improved through more complete understanding of the anatomy and physiology of supporting and contiguous structures. Wide study of mandibular move- ment, intraoral relations and occlusion resulted in improved artificial tooth forms, elimination of cuspal interference, and conservation of support- ing structures. Vulcanite as a denture base has been replaced by the plastics. The most significant development in dentistry and in prosthetics was the growth of emphasis on treatment planning. The viewpoint has changed from a narrow technological approach to a broader concept where the eradication and prevention of disease and the restoration and maintenance of masticatory function is the objec- tive of the dentist. The repair of the individual dental unit is incidental to a comprehensive treatment including diagnosis, prophylactic, sur- gical, and restorative care of the entire dentition. What lies ahead for dentistry in the second half of the twentieth century cannot be pre- dicted. It rests in the hands of the vounger and future members of the profession whose broader training and greater scientific knowledge will continue to advance dentistry as a branch of the healing arts. The Prosthodontia Staff has great confidence that the members of the Class of 1951 will con- tribute their share to the progress of their pro- fession. We all join in congratulating vou upon the completion of vour undergraduate training and wish you continued success in your future endeavors. Gilbert P. Smith Gilbert P. Smith. D.D.S.

Stomatology The Division of Stomatology, comprising the Sections of Oral Diagnosis, Radiology, and Periodontology, has a number of func- tions. As its name signifies it is primarily concerned with teaching the science of the mouth and its diseases with emphasis upon the relationship to general body economy. The knowledge acquired during earlier years in the basic sciences is reviewed and utilized for the critical study of oral disease. Every attempt is made to correlate instruction current with the newer concepts and the philosophy stressed that continual study after graduation is essential for future progress. Through the Section ot Oral Diagnosis it also serves as an interdivisional consultant group and emergency station. It strives to bring about a closer alliance between divisions thereby strength- ening our teaching efforts. In addition to the scheduled undergraduate teaching, courses of instruction are arranged for all post-graduate students registered in the institution. Lewis R. Stowe LEWIS R. STOWE, D.D.S. Professor of Dentistry Diagnosis and Radiology It is with sincere gratification that we, the members of the Diagnosis and Radiology staff, have followed the gradual develop- ment of student interest and participation in the various courses under our control. Ease of digestion and assimilation of material brought about by proper emphasis on basic fundamentals and oral- systemic disease relationships can, in large measure, lav claim to this credit.
