Disasters produce victims that require identification. Comparing antemortem and postmortem dental records provides an important means of identification. Computers have assisted this process. Currently, the principal computer programs are CAPMI4 and WinID2. The present study compared these programs on a sample of 100 simulated victims and 105 simulated postmortem fragments. CAPMI4 provided 48 correct matches and WinID2 provided 71 correct matches. In addition, comparisons were made within WinID2 to determine which of its three dental data sets was the most successful for suggesting correct matches.
