RESUMEN
With the support for curriculum change expressed by the American Dental Education Association's Commission on Change and Innovation in Dental Education (ADEA CCI), the Louisiana State University Health Sciences Center School of Dentistry (LSUSD) initiated a course that vertically integrates the basic sciences and clinical sciences and promotes critical thinking. The resulting Dental Rounds course includes presentations by D3 and D4 students on interesting clinical cases, which the entire student body is required to attend. Following the third year of the program, a formal evaluation was conducted, in which surveys were disseminated to students, recent graduates, and faculty members to collect feedback on the efficacy of the course, its perceived value, and its success as an educational tool. Of the 242 students and graduates who were sent surveys, 181 responded, a 74 percent response rate. Of the eighty full-time faculty members, sixty-one responded, a 76 percent response rate. Most respondents reported that the objectives of the course were being achieved, but they identified case-related discussion as an area for strengthening critical thinking skills. As a result, modifications were planned to include formal participation of D1 and D2 students in the presentations, less frequent sessions to accommodate more complete cases, more emphasis on basic science, more structured mentoring, and a modified question format. Dental Rounds was a necessary integration step in dental education for LSUSD, and it is anticipated that the planned modifications will lead to strengthening of critical thinking skills in both students and faculty.

New carbide burs that are placed on a bur block can be subjected to multiple steam autoclaving cycles prior to their first use. The decision to discard a bur before or during cavity preparation is a subjective one based on operator expectations and experience. This study examined the durability of carbide burs after multiple autoclaving cycles by judging not only their initial sharpness but also their ability to maintain sharpness throughout a cavity preparation. Five experienced operators were given a set of No. 330 carbide burs that had been separated into five blind categories: those not autoclaved at all and those that had been autoclaved one, two, five, or 10 times. Each operator judged the cutting effectiveness of each bur by making an initial plunge cut through the enamel of a freshly extracted tooth. After the initial plunge cut, each operator used the same set of burs to complete an occlusal cavity preparation in molar models fabricated from composite restorative material. Each operator was asked to examine the burs for any visual deterioration and to rate the cutting ability of each bur. The burs were also examined for wear under a scanning electron microscope. Based on the results, this study concluded that up to 10 autoclaving cycles did not significantly affect the perception of either initial sharpness or the bur's effectiveness while completing the preparation.

A small collection of antique dental instruments located in the LSU School of Dentistry Library (LSUSD) provides a glimpse into the world of the 19th century dentist. The instruments in this collection, with handles carved from common and rare early materials such as bone, wood, ivory, ebony, cameo, shell and pearl, provide a striking contrast to all-steel instruments of the 20th century. An understanding of their development and function substantially increases appreciation of these instruments, which can be categorized as instruments for oral surgery, prophylaxis, restoration, and general use. In this article, the authors summarize the historical development of each type of instrument and describe the specific items in the LSUSD Library collection.
