Análise volumétrica da câmara pulpar e canal radicular por meio de tomografia computadorizada de feixe cônico como uma nova ferramenta forense para predição sexual e estimativa de idade cronológica

Abstract

The present study analyzed the volume of the pulp and root canal of upper and lower canine teeth as a new forensic tool for sexual prediction and estimation of chronologicalage through images obtained by Cone Beam Computed Tomography (CBCT). For this purpose,118 images of CBCT of upper and lower canines on the left side, selected from the Dental Radiology Clinic of the University of Caxias do Sul, were selected. The total sample was divided, respectively, into four age groups (G1- 20 to 30 years divided into 18 females and 20 males); (G2- 31 to 40, 17 female and 16 male); (G3- 41 to 50 years, 10 female and 13 male); (G4 - 51to 60 years, 10 female and 14 male). Such images are of patients of both sexes between the ages of 20 and 60. For this, two dentistry students from the University of Caxias do Sul (UCS), under the supervision of a Professor of Dental Radiology with the aid ofthe ITK-Snap software, performed the separation and segmentation of the root canals of these teeth. Inrelation to statistical analysis, the analysis of variance, the logistic regression test and theintraclass correlation coefficient were applied for the analysis of the results of the present study.
