Background: Recently, rugoscopy has attracted much attention in forensic science. The purpose of the present study was to investigate the sex differences in morphological structure and number of hard palates rugae.
Materials and Methods: In this cross-sectional observational study, 100 female and male students were enrolled based on inclusion criteria. To investigate the number and shape of palate rugae impressions were provided using hydrocolloid materials. Then impressions were sharpened using a graphical pencil and were reconstructed using Image J software. The Data was analysed with the t-test, and Mann-Whitney statistical
tests (α=0.05).
Results: The total number of the right and left straight rugae was significantly higher in males (p = 0.039). The number of circular rugae on the right side and, primary rugae on the left side of males, was significantly higher (p = 0.048). There was also a significant difference between males and females in the total number of circular rugae (p = 0.003). No significant difference was observed between the two sexes in the other variables. Based on audit analysis, this model correctly predicted 66% of females and 34% of males studied. The ability of this function to classify cases in other samples and in the general case was estimated at 64%.
Conclusion: It can be concluded that the number and morphology of palatal rugae can be used for sex estimation in forensic dentistry but additional studies with a larger sample size are needed to make a definitive statement. |
