Abstract
Background: Identification of the skeletal and decomposing human remains is one of the most difficult skills in forensic medicine. The aim of the study were to evaluate the accuracy of digital panoramic system as quick, easy and reproducible supplement tool in sex identification using certain mandibular measurements in predicting sex. Material and method: The sample in the current study consisted of 280 Arabic Iraqi patients from both sexes and with age range from 20-60 years old divided in four groups .For each patient panoramic image was taken and the following measurements were done with the aid of computer program “AutoCAD 2010”. 1. The distance from mental to mandibular foramina.2. Intercondylar distance. 3. The distance between the mandibular foramina in both sides.4.Mesiodistal width of each mandibular canines.5.Intercanines distance. The data were subjected to a discriminant analysis using SPSS version 13 Results: The various parameters measured for males and females when compared are statistically significantly different. All mandibular measurements gave overall predictive accuracy of sex determination by discreminant analysis (76.8%). The stepwise selection method gave overall predictive accuracy of sex determination by discreminant analysis (76.4%) .Age showed no statistical difference among the studied age groups. Conclusion: Panoramic measurements of mandible bone are useful to support sex determination in forensic radiographic odontology.
