Evaluation of potassium oxalate as a cavity liner.

All dental restoratives exhibit some microleakage. Recent studies disclosed that oxalate salts were superior to Copalite varnish in reducing dentinal permeability, but inferior in reducing microleakage. This study compared the effectiveness of a potassium oxalate solution (DDS) with three other cavity liners (Copalite, Cavi-Line, Prisma Universal Bond) and a no-liner control in reducing microleakage under amalgam restorations. Under the conditions of this study, DDS solution was significantly effective in reducing microleakage under amalgam restorations.

A comparison of four simulation and instructional methods for endodontic review.

The effects of four different endodontic self-instructional review formats (slide-tape, latent-image simulation, computer text simulation, and computer-assisted video interactive simulation) on senior clinical endodontic performance are compared. The senior class of 105 students was divided into eight groups of 13-14 academically equivalent students prior to initiating endodontic treatment in the 1985-86 academic year. With the exception of the control group, each participated in a program designed to review principles of endodontic diagnosis and treatment. All clinical endodontic cases were subsequently critiqued by a calibrated panel of two general dentist and one endodontist. Overall, students in the study group made fewer diagnostic errors compared with those in the control group, while the error reduction in clinical treatment was not significantly reduced between the two groups. No significant difference in error reduction was noted between the simulation formats. Student evaluations, as well as comparative developmental expenditures, are discussed.

A comparison of simulation programs for endodontic review.

Computer-Based Instruction (CBI) has been gaining increasing popularity in the health professions and especially in dental education, but its development is seldom problem-free. This paper describes a longitudinal study of endodontic simulations for senior dental students which employ latent image, computer-assisted video interactive (CAVI), and computer text instruction (CTI). Particular attention is devoted to developmental problems, use of time and manpower, and student performance on and reaction to the pilot test. Preliminary results of the pilot testing demonstrate favorable student performance on the computer-based mode, as well as an enthusiastic acceptance of this format. Future directions and goals of the study are included.

A simulation program for reviewing endodontics.

To reduce repetitive endodontic errors by senior dental students, a formal review program was established. It consisted of a slide-tape and a written, latent-image simulation of an endodontic case requiring diagnostic and treatment decisions. Before undertaking any endodontic cases in the senior year, each student had to complete the program successfully. The program significantly reduced diagnostic errors in six categories for posterior teeth and in four of six categories for anterior teeth. Errors were also significantly reduced in eight of 12 treatment categories for posterior teeth and in five of 12 categories for anterior teeth. Students' opinions of the endodontic review program were quite favorable.
