The Dental Diagnostic Simulation (DDS) System provides an alternative to simulation systems which represent diagnostic case studies of relatively limited scope. It may be used to generate simulated case studies in all of the dental specialty areas with case materials progressing through the gamut of the diagnostic process. The generation of a functional diagnostic case study by the DDS System requires relatively little effort on the part of either a case author or the CAI staff. Any case thus generated exhibits two major areas of emphasis: the gathering of information about the "patient" and his or her dental problem, and the student's submission of diagnoses pertinent to the case.
