“…We observed that bigonial breadth (BgBr) was 72.9±5.6 mm in males and 72.6±5.2 mm in females, however, the difference was not significant. Kallali et al, 10 found 70.9 mm in males and 70.4 mm in females. The mean±SD minimal ramus breadth (M-R-Br) in males was 31.2±1.2 mm and in females was 24.6±0.9 mm.…”

“…We found that the mean Gonial Angle (Go-ang) was 112.6±3.4 mm in males and 122.4±4.2 mm in females. Kalllali et al, 10 found that the Gonial Angle was higher in females (120.4 0 ) as compared to males (114.7 0 ). Elsalam et al, 11 found that the Gonial Angle was 138.3° in males and 140.9° in females.…”

“…The mean±SD minimal ramus breadth (M-R-Br) in males was 31.2±1.2 mm and in females was 24.6±0.9 mm. Kalllali et al, 10 It is evident that estrogen and progesterone hormones play an important role in aggravating bone growth and leads to variation in craniofacial morphology between genders. Hormonal changes produce 5-9% bigger craniofacial aspects in males as compared to females.…”

Context: Gender determination is an important component of personal identification. Aims: Assessment of gender using mandible with Cone Beam Computed Tomography (CBCT). Settings and Design: This cross-sectional prospective study was conducted on dental outpatients in the department of Oral Medicine and Radiology. Methods and Material: 148 dental outpatients were selected and subjected to CBCT. Mandibular landmarks such as gonial angle, alveolar ridge to mental foramen distance, mental foramen to the inferior border of mandible distance, mandibular canal to the most anterior tangent point of buccal and lingual mandibular plate distance, mandibular canal border to the lowest tangent point on the inferior border of the mandible, coronoid height, bigonial breadth, minimal ramus breadth and ramus length were assessed on CBCT scan. Statistical Analysis Used: Data was represented as mean and Standard Deviation (SD). Parameters were compared between males and females using Kruskal-Wallis and Student’s independent T-test. A value below 0.05 represented significant results. Results: All parameters except gonial were significantly higher in males as compared to females angle (P< 0.05). The distance from the lowest point of the mandibular canal to the most posterior tangent point of the Mandibular Lingual Plate (MCLM) and bigonial breadth was higher in males than females but the difference was non-significant (P>0.05). The accuracy of CBCT was found to be 89.7% in males and 88.5% in females. Conclusions: Gender determination by morphometric analysis of the mandible using cone beam computed tomography is an effective method and provides higher accuracy as compared to two-dimensional conventional radiographs.

“…12, 15 Kharoshah et al (2010) conducted a study for analysing the sexual dimorphism in mandible by 3D-CT in 2010 by taking the different mandibular parameters in this study and concluded that BIC-Br, G-angle, and minimal Ramus-L have significant sexual dimorphism with overall accuracy of 83.9%, however, their study showed significant statistical difference with the G-angle, Ramus-L, G-G-L, BIC-Br, and CO-L (P < 0.05) with overall accuracy of 84%. 8,14 Dayal et al (2008) reported the assessment of sex using 120 skulls, using 6 mandibular measurements, and the application of discriminant function analysis and had an average accuracy of 85%. The study concludes that the stepwise feature discriminant analysis could identify the gonial angle and ramus length, gonion-gnathion length and bigonial breadth as final predictors of sex determination with overall predictive accuracy of 83.2% as the best predictor of sex dimorphism.…”

Background : Identification of personal is one of important aspects in forensic odontology, because it is one of the core aspect of forensic science. The one methode of sex determination is measurement of mandibular. The mandibular is a largest and most powerful facial bone in the skull, which is generally resistant to postmortem damage and an important source for personal identification. Previous studies have studied gender and age prediction using CBCT reconstructive images in a different picture.The objective of this study is to determine the sex determination of os.mandibular using CBCT anthropometric measurements.Materials and Methods : This study involved twenty subjects (10 male and 10 female) with age group between 20 and 35 years. CBCT scans were performed on all subjects, and the data obtained is reconstructed for 3D viewing. After getting a 3D CBCT scan, measurements were taken on six parameters.Results : The differential mean of male and female is 1,7 mm (Ramus-L), 2,1 mm (Con-Cor), 6,9 mm (BG-Br), 7,3 mm (BIC-Br), 3,5 mm (BH 1st molar) dan 3,8 mm (BH canine). The collected data were analyzed using SPSS statistical with Independent T-Test and Logistic Regression test and also Discrimant Function. The results showed that of the six parameters, BG-Br and BIC-Br showed 0,0 (P<0,05) statistically significant differences, with the accuracy of the prediction of gender determination on BIC-Br 70% for male and 80% for female and the overall BG-Br yield of 80% to both group. Conclusion : Sex determination using mandibular with 3D imaging methods can be used and helps in sex determination with 80% accuracy.

“…Computed tomography scan is an imaging procedure that produces multiple images according to different tissue structure (Liguori et al, 2015). CT is a useful imaging method which can be used in the process of human identification and has multiple advantages as compared to traditional radiographic methods (Kallalli et al, 2016). Therefore, this study aimed to determine forensic sex using sacrum and coccyx CT on a sample of Libyan population in Benghazi through measuring ASL, PSL, ASCL, PSCL, ASW, CLS, LAS, MDB and MTDB.…”

Background: Sex identification of human skeleton is essential for bioarcheological and forensic studies. Determination of Sex is important to establish personal identity. Sex identification accurately depends on the presence of complete remains. Aim: This study aimed to estimate sex from measurements of sacrum and coccyx by computed tomography (CT) of Libyan population. Subjects and methods: A cross-sectional study was carried out in Radiological
