Abstract:
Objective To analyze the morphological matching rate with a digital image recognition system in pre-and post-orthodontic treatments,and to provide forensic dentistry evidence for individual identification.Methods High-resolution digital images of the palatal rugae were taken under particular conditions from each patient in pre-and post-orthodontic treatments.Features of each digital image were extracted using a digital image recognition system and collected in the palatal rugae database.Data of the palatal rugae werematched by MATLAB software system.Results From the matching results,the accuracy rate of individual identification of orthodontic patients was 100%.The accuracy rate in matching palatal rugae patterns in pre-and post-orthodontic treatments was 95.67%.The results were statistically significant with P<0.05.Conclusion Palatal rugae pattern is highly individual-specific.The morphologyofpalatal rugaecould bechangedby theorthodontic treatment,however,these changes may not greatly influence individual identification in forensic dentistry,providing a new potential to individual identification.
